What else would I have to change if I changed the while statement to “while (menu == 5) ;”

#include <stdio.h>

void printHelp () {

printf (“\n”);

printf (“a: a(x) = x*x\n”);

printf (“b: b(x) = x*x*x\n”);

printf (“c: c(x) = x^2 + 2*x + 7\n”);

printf (“s: shrink(x) = x/2\n”);

printf (“q: quit\n”);

}

void a(float x) {

float v = x*x;

printf (” a(%.2f) = %.2f^2 = %.2f\n”, x, x, v);

} // end function a

void b(float x) {

float v = x*x*x;

printf (” b(%.2f) = %.2f^3 = %.2f\n”, x, x, v);

} // end function b

void c(float x) {

float v = x*x + 2*x + 7;

printf (” c(%.2f) = %.2f^2 + 2*%.2f + 7 = %.2f\n”,

x, x, x, v);

} // end function c

void shrink(float x) {

float v = x/2;

printf (“shrink(%.2f) = %.2f / 2 = %.2f\n”,x,x,v);

}

int menu () {

char selection;

float x;

printHelp ();

scanf (“%s”, &selection);

if (selection == ‘q’) return 1;

scanf (“%f”, &x);

if (selection == ‘a’) a(x);

if (selection == ‘b’) b(x);

if (selection == ‘c’) c(x);

if (selection == ‘s’) shrink(x);

return 0;

} // end function menu

int main() {

while (menu() == 0);

printf (“… bye …\n”);

return 0;

}
