关于键盘若干个键不能识别的问题
我用getch（）函数读取键盘，但是发现CTRL和shift和win键和Caps Lock和 Num Look等不能识别。请问如何识别这些键呢？
程序代码：#include <stdio.h>
#include <conio.h>
void main(void)
{
int ch, scan;
do {
ch = getch(); /* 1st getch() gets ASCII code */
printf("Character is %d\n", ch);
if (ch == 0x00 || ch == 0XE0) { /* if extended key */
scan = getch(); /* 2nd getch() gets "scan code" */
printf("\tExtended character: scan is %d\n", scan);
}
} while (ch != 27); /* exit loop on ESC */
}
