[C++知识库]c/c++ 简约桌面时钟

偶然注意到，任务栏的时钟是那么丑，就小小的一块，还灰不溜秋的。于是一狠心，自己写了一个时钟，放在桌面上，效果还不错。代码如下：

#include <iostream>
#include <windows.h>
#include <cstdlib>
#include <ctime>
#include <conio.h>
#include "HideCursor.h" 

using namespace std;

int main(){
	HideCursor();
	system ("mode con cols=30 lines=5");
	system ("color e0");
	system ("title clock");
	char ch = '`';
	while (1){
		if (kbhit()){
			ch= getch();
		}
		if (ch == 'f'){
			system ("cls");
			cout<<endl;
			time_t now_time=time(NULL);  
			tm*  t_tm = localtime(&now_time);
			cout <<"   "; 
			printf("%s\n", asctime(t_tm));
			SYSTEMTIME sys; 
			GetLocalTime( &sys );   
			cout <<"      "<< sys.wYear<<"/"<<sys.wMonth<<"/"<<sys.wDay<<" "<<sys.wHour<<":"<<sys.wMinute<<":"<<sys.wSecond;
		}
		if (ch == 'j'){
			system ("cls");
			cout<<endl<<endl;
			SYSTEMTIME sys; 
			GetLocalTime( &sys ); 
			cout <<"         "<< sys.wHour<<" : "<<sys.wMinute<<" : "<< sys.wSecond;
		}
		if (ch == '`'){
			system ("cls");
			cout <<endl<<endl<<"       ";
			cout << "单击f或j键选模式";
			Sleep(1000);
		}
		Sleep (1000);
	}
	return 0;
} 

其中用到一个头文件，可以去我的专栏c++隐藏光标里面复制。
效果如下：

还不错吧~
