ATM Project I started the ATM project when i first started programming. It is a simple emulator of the ATM Machine. This is an example of bad programming. MAIN.CPP #include <stdio.h> #include <conio.h> #include "sysfunc.h" #include "atmfunc.h"
#define KEY1 49 #define KEY2 50 #define KEY3 51 #define KEY4 52 #define KEY5 53
int main() { int mainsel; int pin[5];
cls();
printf("Enter Pin Number\n"); pin[1] = getch(); pin[2] = getch(); pin[3] = getch(); pin[4] = getch();
if(pin[1] == KEY1 && pin[2] == KEY3 && pin[3] == KEY5 && pin[4] == KEY2) {
} else { goto end; }
cls();
start:
printf("Enter Selection\n");
printf("1\tDisplay Balance\n"); printf("2\tDeposit Funds\n"); printf("3\tTransfer Funds\n"); printf("4\tWithdraw Funds\n"); printf("5\tExit\n\n");
mainsel = getch();
if(mainsel == KEY1) { db(); }
if(mainsel == KEY2) { df(); }
if(mainsel == KEY3) { tf(); }
if(mainsel == KEY4) { wf(); }
if(mainsel == KEY5) { goto end; }
goto start;
end: cls(); } ATMFUNC.CPP #include <stdio.h> #include "sysfunc.h"
int balance = 254; int allow = 200;
int db() { cls();
printf("\nCurrent Account Balance: %d\n\n\n",balance);
return 0; }
int df() { int add;
cls();
printf("Enter Ammount to Add to Account\n"); scanf("%d", &add);
balance = balance + add; cls();
printf("\n\nNew Account Balance: %d\n\n\n", balance);
return 0; }
int tf() { cls();
printf("Sorry, Service Unavailable at the Moment\n\n\n");
return 0; }
int wf() { int with;
cls();
printf("Enter Ammount to Withdraw\n"); scanf("%d", &with);
cls();
if( with > 201 ) { printf("Sorry, Can only take out $200\n\n"); }
if( with > balance ) { printf("Sorry, balance is to low\n\n"); }
if( with > allow ) { printf("Sorry, Daily Allowance is only $200. Please come back tomarow\n\n"); }
if(with < 201 && with < balance && with <= allow) { balance = balance - with;
printf("New Account Balance: %d\n\n",balance);
allow = allow - with;
}
return 0; } ATMFUNC.H //ATM Functions SYSFUNC.CPP #include <stdlib.h> void cls() { system("cls"); }
void EXIT() { system("exit"); }
