Question

Consider the following C program:

#include <stdio.h>

int jumble (int x, int y)

{

x = 2* x + y;

return x;

}

int main ( )

{

int x = 2, y = 5;

y = jumble (y, x);

x = jumble (y, x);

printf("%d\n", x);

}

The value printed by the program is _________.

Answer 1

main()	jumble(int x, int y)
y = jumble(5, 2) ∴ y = 12	x = 5 and y = 2 x = 2 × 5 + 2 = 12 return 12
x = jumble(12, 2) ∴ x = 26 printf ("%d\n", x); // output 26	x = 12 and y = 2 x = 2 × 12 + 2 = 26 return 26
