数字时钟c语言代码

制作一个电子时钟C语言版平常我们常见的电子时钟，能够显示当下的时分秒信息，并且能够随时变化递增，记录着时间的流逝。

今天，我要用c语言来制作这样一款电子时钟，看时间这把杀猪刀如何“一刀一刀”溜掉。

我会一步一步引导大家了解制作过程。

首先，我们可以想到，需要获取系统的时间函数，并且显示在cmd控制台中。

time.h是c/c++日期和时间头文件，用于获取系统日期和时间等要求。

首先给出提取显示当前时间的1.0版本电子时钟。

#include<stdio.h>#include<time.h>#include<string.h>int main(){char str[50];//定义字符串用于存储时间time_t t;struct tm *nt;//tm是time.h中定义的一个结构体t=time(NULL);nt=localtime(&t);//获取当前时间strftime(str,50,"%Y-% m-%d %H:%M:%S ",nt);//strftime是根据当前计算机区域设置格式化本地时间日期printf("现在时刻：%s\n",str);//打印现在时刻getch();return 0;｝运行的结果如下：可以看出，的确做到了显示当前时间，但是很明显这不是电子时钟，电子时钟要不断运行变换时间，而不是让时间凝滞。

那么，我们怎么实现真正的电子时钟呢？我们一起思考：如果要实现时间变化，需要不断重新获取当前时间，并且将之前的显示清除掉，然后再打印显示当前时间，这样循环往复。

所以，需要增加一个while(1)死循环，同时要增加一个清屏函数，清除原来的显示。

清屏函数常用的就是system("cls")。

下面是改进后的2.0版代码。

#include<stdio.h>#include<time.h>#include<string.h>int main(){char str[50];time_t t;struct tm *nt;while(1){system("cls");//清屏函数t=time(NULL);nt=localtime(&t);strftime(str,50,"%Y-%m-%d %H:%M:%S “，nt);printf("现在时刻：%s\n",str);}getch();return 0;}然后运行程序，就可以实现电子时钟了，时间不断刷新，秒数递增，时间随之递增。
