Hi All,
I need help figuring out how I can call the various functions in this program from main. I've figured out as much of the code I could, but now I'm stumped. Any help would be appreciated.
#include <stdio.h>
float deposits[50] = {0};
float withdrawals[50] = {0};
char first_name[20] = {0};
int num_withdrawals, num_deposits, x;
float start_bal;
float current_balance = 0;
float total_deposits = 0;
float total_withdrawals = 0;
float balance;
float get_startingbalance(void);
float getCntOfWithdrawls();
float getCntOfDeposits();
float getEachDeposit();
float getEachWithdrawl();
float checkBalance();
float calcAndDisplayBalance();
float displayBankRecord();
int main (void)
