我想在这个程序中实现:将用户信息数据:如用户名,密码,账户金额引入txt文本,并在下一次实现功能时
,从txt中读取相关用户名,密码,金额。挂失数据暂不考虑,请避免用户名,密码,余额,不对应。txt文件名为data.txt

#include<stdio.h>
#include<string.h>
#include<stdlib.h>
int AccountCheck();   //用户名验证
int ReportLossVerification(int);   //挂失验证
int Code(int);     //密码函数
float Total=0;          //// 定义全局变量T,记录用户一天取款数的总和
void Withdrawal ();      //取款函数
void SaveMoney ();     //存款函数
void Inquire();      //查询函数
void SellingHousehodes();   //销户函数
void CreateNewAccount();       //开户函数
void Transfer();  //转账函数
void Loss();      //挂失函数
void Exit();      //退出函数
void CheckAllInfro();      //查询所有用户信息






char UserName[100][30];               //用户名
char CodeStr[100][30];               //密码
char LossName[100][30];                //挂失用户名


float RemainAmount[100];                 //存款余额
int UserNumber=0;                 //用户数
