### Subject:C Programming

TutorMe
Question:

What output does this C function produce when called? int doStuff() { int x; int y; int* z; x = 5; y = 9; z = &x; (*x) = y; z = 7; return x; }

The answer is 9. While x originally equalled 5, it was assigned the value of y, which is 9. Modifying z which pointed to x does not change the value of x.
