我的C/C++之路-007課(模仿ATM取款程序)

下面模仿下ATM取款機，有錢真好！！！

輸入密碼正確後可以：取款，存款，退出

[cpp]
#include<stdio.h> 
/*

int strCompare(char *,char *); 
int accountVerify(); 
void accountOperate(); 
 
void simulateOfATM()

//不使用自帶的strcmp，自己寫個玩玩 
int strCompare(char *str1,char *str2) 
{ 
    while(*str1&&*str2&&(*str1==*str2)) 
    //while(*str1!='\0'&&*str2!='\0'&&(*str1==*str2))//這個效率低點，不過容易理解 
    { 
        str1++; 
        str2++; 
    } 
    return *str1-*str2; 
} 
//通行驗證  www.2cto.com
