Description

ATM is an electronic instrument that serves bank clients to take cash and check their investment accounts without being served by a human teller. Numerous ATM likewise serve to store cash or checks, exchange cash or even purchase mobile phone credit.

Here is the flowchat of the ATM System that we will make.

In an ATM available menus as follows pull cash, balance, transfer

• Withdraw
  If the user will withdraw the amount of money, select Cash Withdraw> Number to withdraw, and will display Details of cash withdrawal whether the user will continue the transaction or not, if "Yes" then the user's balance will decrease as much as the nominal withdrawn, if "No" then will return.

• Transfer
  If the user will transfer the amount of money, select transfer funds> Nominal (Amount) Transfer, then will appear Transfer details and question whether the user will continue the transaction or not, if "Yes" then the user's balance will be reduced as much as nominal transferred, if "No "Then it will come back.

• Balance
  This menu serves to check the remaining balance that is in the user account.

Here is the sourcode:

'#include   
 #include   
 int main(void)  
 {  
 int pilihan;  
 int transaksi,saldo=2000000,setor;  
 printf("------------+ATM Bank ABC+------------\n1.Tarik Tunai\n2.Transfer\n3.Informasi Saldo\n");  
 printf("------------------+++------------------\nMasukan Pilihan Anda : ");  
 scanf ("%d", & pilihan );  
 switch (pilihan)  
 {  
      case 1:  
           printf("\n 1.Withdrawal\n ");  
           printf(" input amount: ");  
           scanf("%d",&transaksi);  
           saldo-=transaksi;  
           printf(" Your Balance Now : %d\n",saldo);  
      break;  
      case 2:  
           printf("\n 2.Transfer\n");  
           printf(" Input Amount : ");  
           scanf("%d",&setor);  
           saldo+=setor;  
           printf(" Your Balance Now : %d\n",saldo);  
      break;  
      case 3:  
           printf("\n 3.Balance\n");  
           printf(" Your Balance Now : %d\n",saldo);  
      break;  
      default:  
           printf("wrong command (Enter 1-3)\n");  
      break;  
 }  
 system("pause");  
 return(0);  
 }  '

Result Work :

Program description:

Notice the sourcode below:

'case 1:  
           printf("\n 1.Withdrawal\n ");  
           printf(" input amount: ");  
           scanf("%d",&transaksi);  
           saldo-=transaksi;  
           printf(" Your Balance Now : %d\n",saldo);  
      break; '

if you select 1 then it will generate the output "input amount" then after the amount in input, your balance and the withdrawal amount will be reduced, and then generate the balance output now. And it will look like the following:

" case 2:  
           printf("\n 2.Transfer\n");  
           printf(" Input Amount : ");  
           scanf("%d",&setor);  
           saldo+=setor;  
           printf(" Your Balance Now : %d\n",saldo);  
      break;  "

if you select 2 then it will generate output "input amount" then after amount in input, your balance and transfer amount will be subtracted, and then generate balance output now.

Examples like the following:

"
case 3:  
           printf("\n 3.Balance\n");  
           printf(" Your Balance Now : %d\n",saldo);  
      break;  
"

if you select 3 then it will automatically generate your balance output now.

For example seprti following :

"
   default:  
           printf("wrong command (Enter 1-3)\n");  
      break;  
"

if the input is not 1,2,3 it will come out like this.
