Max Marks: 70 Time: 3 Hrs

Q1)
a) Differentiate between ordinary function and member functions in C++. Explain
with an example. (2)
b) Write the related library function name based upon the given information in
C++. (1)
i) Terminate the program. This function is available in process.h file.
ii) To join a string at the end of another string. This function is available in
string.h file.
c) Rewrite the following program after removing the syntactical errors (if any).
Underline
each correction. (Assuming all desired header file(s) are already included) (2)
typedef char[50] STRING;
Void main( )
{
city STRING
gets(city);
cout << city[0] << ‘::’ << city[2];
cout << city << endl;
}
d) Find the output of the following program:
(2)
# include <iostream.h>
struct score
{
int year;
float topper;
};
void change(score * s, int x = 20)
{
s−>topper = (s−>topper + 25) – x;
s−>year++;
}
void main()
{
Score arr[ ] = {{2007, 100}, {2008,95}};
score * point = arr;
change (point, 50);
cout << arr[0].year << ’#’ << arr[0].topper << endl;
change(++point);
cout << point−>year << ’#’ << point−>topper << endl;
}
e ) Study the following program and select the possible output(s) from the option (i)
to
(iv) following. Also write the maximum and minimum values that can be assigned
to
the variable value. (2)
# include <iostream.h>
# include <stdlib.h>
void main( )
{
randomize( );
int value;
value = random(2) + 2;
char yourself[ ] = {“ONE”, “TWO”, “SIX”, “TEN”};
for (int y = 0; y < value; y++)
cout << yourself[y];
cout << “END” << endl;
}
