发布时间:2022-05-05 10:13:27 来源:亿速云 阅读:154 作者:iii 栏目:开发技术

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 <time.h>  -- 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 <windows.h>
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 <stdio.h>
#include <time.h>
#include <stdlib.h>
#include <conio.h>
#include <windows.h>
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;
    gotoxy(x*3,8);
    printf(" **");
    gotoxy(x*3,9);

    gotoxy(x*6,11);
