Question 4

What is the output of the following program?

#include <stdio.h>
int funcf (int x);
int funcg (int y);

main()
{
    int x = 5, y = 10, count;
    for (count = 1; count <= 2; ++count)
    {
        y += funcf(x) + funcg(x);
        printf ("%d ", y);
    }
}

funcf(int x)
{
    int y;
    y = funcg(x);
    return (y);
}

funcg(int x)
{
    static int y = 10;
    y += 1;
    return (y+x);
}
A
43 80
B
42 74
C
33 37
D
32 32
Question 4 Explanation: 
In first iteration:
In first case of funcf, which in turn calls funcg, y becomes 11 and it returns 5+11 = 16.
In second call of funcg, y becomes 12 and it returns 5+12 = 17.
So, in main y is incremented by 16+17 = 33 to become 10+33 = 43.
In second iteration:
y will be incremented by 18+19 = 37 to give 43+37 = 80.
Correct Answer: A
