小編給大家分享一下C++如何模擬實現鍵盤打字程序，相信大部分人都還不怎么了解，因此分享這篇文章給大家參考一下，希望大家閱讀完這篇文章后大有收獲，下面讓我們一起去了解一下吧！
程序演示：
程序代碼：
#include<graphics.h>
#include<iostream>
#include<conio.h>
#include<time.h>

void showBoard();//畫鍵盤
void showText();//顯示鍵值
void acceptAction();//獲取響應
private:
int randomKey;//隨機值
int Struct;//支撐體
int keySize;//鍵塊大小
int x1, y1;//第一行的第一個鍵塊左上角坐標
