使用銀行程序的文本文件在C

Question

我已經差不多完成了這個銀行程序在你的幫助下（我之前曾問過關於同一個代碼的問題）。但我想鏈接銀行賬戶用戶的號碼和他的餘額C代碼與文本文件。我不知道這是否可能，因爲我是編程新手。我在這個網站上看到了其他相關的問題，因此我問了這個問題。謝謝！

#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; 
    default: 
     printf("Invalid Input\n"); 
     break; 
    } 
} 
_getch(); 
} 

Answer 1

有一個結構

struct BankAccount 
{ 
    int AccountNo; 
    int Balance 
} Accounts[NUM_OF_ACCOUNTS] 

讀/寫文件中使用結構格式

當然

你能做到這一點！

只是熟悉處理與文件打交道的C.你自己這裏有一個很好的教程 http://www.tutorialspoint.com/ansi_c/c_working_with_files.htm
