C语言怎么实现基于控制台的电子时钟

这篇文章主要介绍"C语言怎么实现基于控制台的电子时钟"，在日常操作中，相信很多人在C语言怎么实现基于控制台的电子时钟问题上存在疑惑，小编查阅了各式资料，整理出简单好用的操作方法，希望对大家解答"C语言怎么实现基于控制台的电子时钟"的疑惑有所帮助！接下来，请跟着小编一起来学习吧！

使用到下面这些技术:

首先必须先导入库

/***************** 实时数字时钟(和计算机系统时间关联) **************#include   -- 必须的时间函数头文件time_t -- 时间类型（time.h 定义）struct tm -- 时间结构，time.h 定义如下：（依需求选用）int tm_sec;int tm_min;int tm_hour;int tm_mday;int tm_mon;int tm_year;int tm_wday;int tm_yday;int tm_isdst;time(&rawtime); -- 获取时间，以秒计，从1970年1月一日起算，存于rawtime                -- 获取到当前的秒数,参数为0则函数返回值即为结果localtime(&rawtime); -- 转为当地时间，tm 时间结构system("cls");--命令行清屏

获取坐标的代码如下

#include void gotoxy(int x,int y)    //光标定位函数，需要包含windos.h头文件{    COORD coord;    coord.X=x;    coord.Y=y;    SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE),coord);}

源代码:

#include #include #include #include #include void gotoxy(int x,int y)   //光标定位函数，需要包含windos.h头文件{    COORD coord;    coord.X=x;    coord.Y=y;    SetConsoleCursorPosition(GetStdHandle(STD_OUTPUT_HANDLE),coord);}void dians(){    int x=8;
