这是主函数:

#include<stdio.h>
#include"f.cpp"
int main()
{
    int i;
    char str[10];
    printf("请输入密码:\n");
    gets(str);
    i=f(str,"password!");
    if(i) printf("\n恭喜，密码正确！");
    else printf("\n抱歉，密码错误！");
}

****************************下面是f.cpp文件内容********************

int f(char str[],char pw[])
{
    int i;
    while(str[i]==pw[i] && str[i]!='\0' && pw[i]!='\0')
        i++;
    return !(str[i]-pw[i])
