在您的帮助下，我几乎完成了这个银行程序（我之前曾就相同的代码提出过问题）。但我想将这个 C 代码中的银行账户用户的号码和他的余额与一个文本文件相关联。我不知道这是否可能，因为我是编程新手。我在这个网站上看到了其余的相关问题，因此我问了这个。谢谢！
#include<stdio.h>
#include<conio.h>
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", &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", &option);
switch(option)
{
case 1:
printf("Enter the amount you want to deposit\n");
scanf_s("%d", &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", &wicash);
wibal=balance-wicash;
if(wicash<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;

_getch();
