So this program is not outputting the proper value for numDeposit or numCheck, it outputs a value of zero for both of these. I think the prime area of interest is the main function and the bottom function but I can't see what I did wrong.

#include <stdlib.h>

void check(double amount, double *balance, double *service, int *numCheck, double *amtCheck);
