{
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. Marks [3]

Q 9: Write the procedure of data insertion in middle of the files by merge method, as practiced in older systems?

Q 10: Do you agree that in good programming practice the main() function is smaller than the class implemented. If your answer is No then argue and if Yes then support your answer briefly. Marks [5]

};
Write the operator function of stream extraction operator(>>) for this class. Marks [5]
Q 12: What is meant by user interface and class interface in c++? And what role a class interface can play in user interface. Marks [5]
Question 1:
Identify each of the following as system software and application software.
LINUX, DISK CLEANUP, WORD PROCESSOR, WINDOWS, STUDENT INFORMATION (mark 5)
Q2:
Write the explanation of this program. See program from book pg no534. (mark5)
Q3: Write a program which defines three variables of type double which store three different values including decimal points, using set precision manipulators to print all these values with different numbers of digits after the decimal number.(5)

2.What is difference between Unary and binary operators and how they can be overloaded?
3.how many types of templates?
4.What will be the output of following function if we call this function by passing int 5?
template T reciprocal(T x) {return (1/x); }
5. Identify the errors in the following member operator function and also correct them.
math * operator(math m);
math * operator (math m)
{
math temp;
temp.number= number * number;
return number;
Answer:
The errors are in the arguments of the member operation function and also in the body of operator member function.
Correct function should be
math *operator(math *m);
math *operator (math *m)
{
math temp;
temp = m;
temp.number= number * number;
return temp.number;
Q: define buffer?explain its usage? 5 MARKS
Q: why binary search algorithm is efficient than linear search algorithm? 5 marks

Q: perator function ka syntex(3 marks)

Q:
post increment and pre increment k syntex btana thay(2 marks)

Q:what is language translator?(2 marks)

Q:
write somethiing something about testing in designing program? 3 MARKS

Q:Read the given below code and explain what task is being performed by this function 5 MARKS

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

Which one (copy constructor or assignment operator) will be
called in each of the following code segment?
1) Matrix m1 (m2);
2) Matrix m1, m2;
m1 = m2;
3) Matrix m1 = m2;
1.what is diffrent between pointer and variable?
Pointers
Pointer is a special type of variable that contains a memory address.
Variables are locations in memory for storing data.

2.What is difference between Unary and binary operators and how they can be overloaded?
Unary operators are the ones that require only one operator to work. Unary operators are applied to the left of the operand. For example, ^, &, ~ and !.
Binary operators require two operands on both sides of the operator. +, -, *, /, %, =, < and > are examples of binary operators.

3.how many types of templates?
There are two different types of templates in C++ language i.e.’ function templates and class templates.

4.What will be the output of following function if we call this function by passing int 5?
template T reciprocal(T x) {return (1/x); }

1/5

5. Identify the errors in the following member operator function and also correct them.
math * operator(math m);
math * operator (math m)
{
math temp;
temp.number= number * number;
return number;

Answer:
The errors are in the arguments of the member operation function and also in the body of operator member function.
Correct function should be
math *operator(math *m);
math *operator (math *m)
{
math temp;
temp = m;
temp.number= number * number;
return temp.number;
