监听键盘，按下a时输出b和c，按下ESC终止程序。
#include <stdioh>
#include <conioh>
#include <stdlibh>
int main()
{
char ch;
while(!kbhit())
{
ch = getch();
switch(ch)
{
case 'a':
printf("bc");
break;
case 27:
exit(0);
}
}
return 0;
}
这个程序应该满足你的要求吧。
#include <stdioh>
#include <conioh>
int main(void)
{
while (1)
{
if (!kbhit())
printf("1");
else
{
char c = getch();
if (c == 'a')
{
putchar('2');
getch();
}
}
}
return 0;
}
命令行输入是不响应很多组合键的
所以要想读取快捷键，那么就要从系统层面读取
而不是用库函数
在Windows下可以用key hook
在linux下可以读取input event
#include<iostream>/GetKeyState（）函数是windowsh中的函数,当括号内的键被按下时，其值小于0，/
#include<windowsh>/并且只要在只要键处于被按下的状态，其值都会小于0，当键被松开时，其值大于0/
using namespace std;
int main()
{
while(1){
if((GetKeyState(VK_CONTROL)<0)&&(GetKeyState('A')<0)){
cout<<"CONTROL+A";
while(GetKeyState(VK_CONTROL)<0&&GetKeyState('A')<0) ;//只要键被按下，就会有一定的持续时间。
}
}
}
//自己耗费1天半的呕心沥血之作，希望对你有用！
cCharTemp=getchar();主要是接受scanf("%c",&cCharPut);这里按的回车，执行程序时，你输入a，然后回车，实际上缓冲区接受的是两个字符，第一个是'a'第二个是‘\n'，scanf("%c",&cCharPut);只把a从缓冲区中取走，但是'\n'还在缓冲区。如果没有getchar这个语句，那么下面的语句scanf("%c",&cCharPut);就会直接读取缓冲区中的'\n‘而不会等到你再去输入字符。而getchar是取走缓冲区中一个字符，把回车给取走，缓冲区空了，你才能再次输入
以上就是关于c语言怎样实现键盘 *** 作全部的内容，包括:c语言怎样实现键盘 *** 作、c语言编贪吃蛇，用什么编译环境，怎么显示贪吃蛇和水果，怎么键盘响应我菜鸟都不算，求指教。、最好用c语言编程，按键位a的时候，键位b和c响应，就是如同是按“1”的时候，输出的是“2”和“3”。等相关内容解答，如果想了解更多相关内容，可以关注我们，你们的支持是我们更新的动力！
