kbhit用C语言
在这里，我们将看到C中的kbhit功能。kbhit基本上是KeyboardHit。此函数位于conio.h头文件中。因此，要使用此文件，我们必须将此头文件包含在我们的代码中。
其功能kbhit()是，当按下某个键时，它返回非零值，否则返回零。
示例
#include <stdio.h>
#include <conio.h>
main() {
char ch;
printf("Enter keys (ESC to exit)\n");
while (1) { //define infinite loop for taking keys
if (kbhit) {
ch = getch(); // Get typed character into ch
if ((int)ch == 27) //when esc button is pressed, then it will comeout from loop
break;
printf("You have entered : %c\n", ch);
}
}
}输出结果
Enter keys (ESC to exit) You have entered : i You have entered : t You have entered : D You have entered : w You have entered : 5 You have entered : / You have entered : * You have entered : + You have entered : You have entered : o You have entered : You have entered : &
注意：这kbhit()不是标准库。因此，我们应该在代码中避免这种情况。
