What is the output for f(-1, 4)?

Question

void f (int x, int y) {

while (x < y) {

printf("%d ", y - x);

x = x + 1;

y = y - 1;

}

}

Answer 1

f(-1,4) --> x = -1 and y = 4

enters while loop as -1 < 4

OUTPUTS 5

x=0

y = 3

while loop: 0 < 3

outputs 3

x=1

y=2

while loop : 1<3

outputs 1

x=2

y = 1

while loop test condition fails

THe output is 5 3 1

Here is the complete code:

#include <stdio.h>

void f (int x, int y)

{

while (x < y)

{

printf("%d ", y - x);

x = x + 1;

y = y - 1;

}

}

int main()

{

f(-1,4);

}
