Question No: 3 ( Marks: 2 )
Give the general syntax of class template.
Answer:
template
class myclass { ---} ;
Question No: 4 ( Marks: 2 )
What is a truth Table?
Answer:
There are some areas where the decision structures become very complicated. Sometimes, we find it difficult to evaluate a complicated logical expression. Sometimes the logic becomes extremely complicated so that even writing it as a simple syntax statement in any language. It becomes complicated to determine what will be evaluated in what way. We know the concept of truth table. The truth tables are very important. These are still a tool available for analyzing logical expressions. We will read logic design in future, which is actually to do with chips and gates. How we put these things together.
Question No: 5 ( Marks: 2 )
What will be the output of following code, if user input a number 123?
int input ;
cin >> oct >> input;
cout hex input ;
Answer:
53
Rational: it will take 123 as octal and print it in hex form which is 53.
Question No: 6 ( Marks: 2 )
What is principle of friendship in the context of functions and classes?
Answer:
Class can declare a friend function and someone from outside the class cannot declare itself friend of a class.
A friend function can access the private variables of class just like a member function
Question No: 7 ( Marks: 2 )
How many arguments a Unary Operator take? Can we make a binary operator as unary operator?
Answer:
Unary operator takes only one argument like i++ or i— (Post increment or post decrement operators for integers) or ++i,--i (Pre increment or pre decrement operators for integers) ,we can not make Unary operator as binary or binary as Unary operator.
Question No: 8 ( Marks: 2 )

Which arithmetic operators cannot have a floating point operand?

Answer:
Modulus operator:
This operator can only be used with integer operands ONLY

Question No: 9 ( Marks: 2 )

What are manipulators? Give one example.

Answer:
The manipulators are like something that can be inserted into stream, effecting a change in the behavior. For example, if we have a floating point number, say pi (ะป), and have written it as float pi = 3.1415926 ; Now there is need of printing the value of pi up to two decimal places i.e. 3.14. This is a formatting functionality. For this, we have a manipulator that tells about width and number of decimal points of a number being printed.

{ for (int b = 0;b<3;b++)
{ matrix[a][b]= inivalue;
cout/p>
}

Question No: 11 ( Marks: 2 )

What is the difference between switch statement and if statement.
Answer:
The “If” statement is used to select among two alternatives. It uses a Boolean expression to decide which alternative should be executed. The switch statement is used to select among multiple alternatives. It uses an int expression to determine which alternative should be executed.

Question No: 31 ( Marks: 5 )

What steps we must follow to design good program?

Answer 1:

Hence to design a program properly, we must:
Analyze a problem statement, typically expressed as a word problem.
Express its essence, abstractly and with examples.
Formulate statements and comments in a precise language.
Evaluate and revise the activities in light of checks and tests and
Pay attention to detail.

Answer 2:

Details: we must check very details of any program. It is very important aspect of any program. We must pay complete attention to calculation.
We must give attention to logic and its flow should be smooth.

Reusable: We must write program in such a way that we can reuse them in other program. Like we define function in such a way that in future if we need any similar kind of function is requires in that case we can easily modify or reuse it.

Comments: we write the details of important steps in the form of comments. We should use comments in such a way if any body else wanted to reuse or debug or codes he can easily understand it.

Code readability: We should use Tab and spaces so codes are easily readable.

User interface: we make interface user friendly. Use polite prompts for user while take input.

Question No: 36 ( Marks: 5 )

What are the advantages and disadvantages of using templates?

Answer:
Many things can be possible without using templates but it does offer several clear advantages not offered by any other techniques:

Advantages:
Templates are easier to write than writing several versions of your similar code for different types. You create only one generic version of your class or function instead of manually creating specializations.
Templates are type-safe. This is because the types that templates act upon are known at compile time, so the compiler can perform type checking before errors occur.
Templates can be easier to understand, since they can provide a straightforward way of abstracting type information.
It helps in utilizing compiler optimizations to the extreme. Then of course there is room for misuse of the templates. On one hand they provide an excellent mechanism to create specific type-safe classes from a generic definition with little overhead.

Disadvantages:
On the other hand, if misused
Templates can make code difficult to read and follow depending upon coding style.
They can present seriously confusing syntactical problems esp. when the code is large and spread over several header and source files.
Then, there are times, when templates can "excellently" produce nearly meaningless compiler errors thus requiring extra care to enforce syntactical and other design constraints. A common mistake is the angle bracket problem.

Question No: 37 ( Marks: 5 )

Suppose a program has a math class having only one data member number.
Write the declaration and definition of operator function to overload + operator for the statements of main function.
math obj1, obj2;
obj2= 10 + obj1 ;

Answer:
#include
math
{
mth operator + (obj1,int x)
{

number temp;
temp=obj1.number+x;
return temp.number;
}
}

Question No: 38 ( Marks: 5 )

Write a program which defines three variables of type double which store three different values including decimal points, using setprecision manipulators to print all these values with different number of digits after the decimal number.

Answer:

#include
#include
main () {
double a = 12.12345;
double b = 13.123456;
double c = 14.1234567;
cout setprecision (5) a endl;
cout setprecision (2) a endl;
cout setprecision (3) a endl;
}

Question No: 39 ( Marks: 5 )

Let we have a class,
class String
{
private:
char buf[25];
};
Write code for assignment (=) operator function which assign one String object to other object. Your code should also avoid self assignment

Answer:
void String::operator = ( const String &other )
{ int length ;
length = other.length();
delete buf;
buf = new char [length + 1];
strcpy( buf, other.buf ); }

Question No: 40 ( Marks: 5 )

Read the given below code and explain what task is being performed by this function
Matrix :: Matrix ( int row , int col )
{
numRows = row ;
numCols = col ;
elements = new ( double * ) [ numRows ] ;
for ( int i = 0 ; i < numRows ; i ++ )
{
elements [ i ] = new double [ numCols ] ;
for ( int j = 0 ; j < numCols ; j ++ )
elements [ i ] [ j ] = 0.0 ;
}
}
Hint : This function belong to a matrix class, having
Number of Rows = numRows
Number of Columns = numCols

Answer:
In the above mentioned code, first of all programmer call the constructor who have two parameters for the number of rows & columns in the matrix. Then this constructor also dynamically allocates the memory for the elements of the matrix & also initializes the value of the all elements of matrix with 0.0

1. After analyzing the findings of the research conducted, you need to identify the ‘key factor’ which compelled KFC’s higher management to launch Big Filler Burger?

Solution:
As a new product launch is always risky. You can never be certain if your product will be a success or a failure. There are, however, ways to predict with reasonable accuracy, whether or not a product will succeed. This can be done by determining the key success factors for a new product. According to Dr. William R. Boulton,
“key success factor fall into five categories: customer requirements, competitive factors that must be met, regulations/industry standards, requirements to implement competitive strategy, and technical requirements to build a competitive position. Determining the precise key success factors for your specific product is simple when using these categories. Following a few easy steps will show you how to determine your key success factors.”
1- customer requirement:
The KFC’s higher management write down a list of customer requirements. These are the things that you know your potential customers want in a product. This can be gathered via market research. An example as it is discribed that the size of the burger is now attracting customers,. Therefore, it is considered a key success factor.
2- Competitive factors:
Write a list of competitive factors that must be met. For example, if you are marketing a new sports drink and all other sports drinks contain caffeine, putting caffeine in your product is a competitive factor that you must meet. Not meeting this factor means that you will likely be unable to compete, so this factor is a key success factor.
3- Regulations/industry standards:
Write a list of regulations/industry standards in your specific business. A food product, for instance, needs to pass certain health requirements. Not meeting these requirements makes it likely that you will be shut down by regulators. Therefore, these requirements are considered key success factors.
4- Resource requirements:

2. How competitors of KFC help in making an idea of Big Filler? Was it market intelligence or market research which helped KFC to take this decision?

Solution:
It was Market research that KFC help in making an idea of Big Filler as KFC was facing severe competition from its competitor regarding size of the burger e.g. BIG MAC Burger by McDonald, Foot Long Burger by Subway etc. The crux of the task was to design a campaign where KFC could stand out among competitors by offering something unique and out of the box. Therefore KFC’s product development team came up with a new idea of introducing “KFC Big Filler Burger”
KFC conducted a research that what the competitors are doing in this regards. Research findings show that Big Mac by Mac Donald and Big Foot by Subway, have received a tremendous response from the market; especially from those customers who are focusing on the size of the product. For that KFC has developed a new product with the name of Big Filler burger. After the launch of this product, they again conducted a research and tried to explore the response of the customer regarding some particular attributes of the product.
