password.c

一些linux基本函数的测试集,给像我一样的新手看看

//功能：简单密码检测程序

#include "stdio.h"

int main()
{
	char pass_str[80]; //定义字符数组passstr
	int I=0;
	int j=1;

	//检验密码

	while(j)
	{
		printf("please inter password:\n");
		gets(pass_str); //输入密码
		if(strcmp(pass_str,"password")!=0) //口令错
			printf("error! go on trying...\n");
		else
		{
			printf("OK!password is right!\n");
			break; //输入正确的密码，中止循环
		}
		I++;
		if(I==3)
		{
			printf("break!check your password and make it sure!\n");
			exit(0); //输入三次错误的密码，退出程序 
		}
	}
	
	return 1;
//输入正确密码所进入的程序段
}
