title: Use a text file for bank program in C
body: <p>i have almost completed this bank program with your help(i had asked a question on the same code earlier).But i want to link the bank account user's number and his balance in this C code with a text file. I don't know whether it is possible or not as i am new to programming. I saw the rest of the related questions on this site and thus i asked this one. Thank you!</p>
  
  <pre><code>#include&lt;stdio.h&gt;
  #include&lt;conio.h&gt;
  int main(void)
  {
  int deposit,withdraw,kbalance;
  int option;
  int decash,wicash;
  int balance;
  int wibal;
  
  printf("Wel0ome to skybank\n");
  printf("Enter your current Balance\n");
  scanf_s("%d", &amp;balance);
  printf("Press 1 to deposit cash\n");
  printf("Press 2 to Withdraw Cash\n");
  printf("Press 3 to Know Your Balance\n");
  printf("Press 4 to Quit\n");
  while((option=getchar())!=4){
  scanf_s("%d", &amp;option);
  switch(option)
     {
      case 1:
          printf("Enter the amount you want to deposit\n");
          scanf_s("%d", &amp;decash);
          printf("Thank You\n");
          printf("%d have been deposited in your account\n", decash);
          balance=balance+decash;
          printf("Your balance is Rs.%d\n",balance);
          break;
      case 2:
          printf("Enter the amount you want to withdraw\n");
          scanf_s("%d", &amp;wicash);
          wibal=balance-wicash;
          if(wicash&lt;balance){
              printf("Thank You\n");
              printf("%d have been withdrawed from your account\n", wicash);
              printf("Your balance is Rs.%d\n", wibal);}
          else{
              printf("Sorry. You have insufficient balance to conduct         this transaction!\n");}
          balance=balance-wicash;
          break;
      case 3:
          printf("Your balance is Rs.%d\n", balance);
          break;
      case 4:
          exit();
          break;
      default:
          printf("Invalid Input\n");
          break;
      }
  }
  _getch();
  }
