Given the following program fragment, write out the output of the printf statement:

#include

int function1(int *x, int *y);

void main(void)

{

int x = 7, y = 20, z; z = function1(&y, &x);

printf (x = %i, y = %i, z = %i, x,y,z);

}

int function1(int *x, int *y)

{ int tmp;

*y = *x + 10; tmp = *y + 40;

return tmp; }
