在实际开发中经常会遇到简单调试接口的场景,需要从键盘输入一个字符,响应相应操作,整体逻辑就是 

1.获取键盘输入

2.执行操作

3.再次等待获取键盘输入

虽然上述步骤极其容易但是总归是需要时间去拉一个demo,下面给出demo 用例,便于大家修改测试

#include <iostream>
#include <string>
#include <vector>#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>using namespace std;
void PrintTestList()
{cout << "*--------------------------------------------------*" << endl;cout << "|       _______    ______     ____     _______     |" << endl;cout << "|          |      |          |            |        |" << endl;cout << "|          |      |_____     |____        |        |" << endl;cout << "|          |      |               |       |        |" << endl;cout << "|          |      |______     ____|       |        |" << endl;cout << "|                                                  |" << endl;cout << "|UAV                      control_valve            |" << endl;cout << "|   1 : control_take_off    3:  control            |" << endl;cout << "|   2 : control_turn_off                           |" << endl;cout << "|                                                  |" << endl;cout << "|                                                  |" << endl;cout << "|0:Exit.                         lt                |" << endl;cout << "*--------------------------------------------------*" << endl;}std::string GetInput()
