你在学习c++中想要的

大多数情况和大多数学校都是让你学习C,然后你需要在控制台操作
那么怎么来改变这个控制台呢?

改变控制台相关参数

由于大多数人使用windows操作系统,我们在代码中需要包括windows.h头文件,直接调用现有的函数来进行操作

获取屏幕鼠标的位置

#include<stdio.h>
#include<windows.h>
int main()
{
    POINT p;
    POINT p1;
    GetCursorPos(&p);
    printf("%ld %ld\n",p.x,p.y);
    while(1)
    {
		p1=p;
        GetCursorPos(&p);
        
        if(p.x!=p1.x || p.y!=p1.y ){
        	printf("%ld %ld\n",p.x,p.y);
		}
        
        //Sleep(1000);
    }
    return 0;
}

让你的黑窗口弹出一个提示框

#include <Windows.h>
#include <tchar.h> //支持通用字符集的一些操作头文件,使用双字节或者大字符集时可以不包含它

int _tmain() {

	MessageBox(NULL, _T("可以更改提示图标和按钮哦~~~"), _T("这是标题哈"), MB_OK |MB_ICONERROR );
	return 0;
}

注1: 你看到这种_T(“一段文件”),tchar.h是为了让代码的移植性更好,以便于自动适应不同的字符集

比如

获取和修改控制台的标题

#include <windows.h>
#include <tchar.h>
#include <conio.h>
#include <strsafe.h>

int main(void)
{
    
    char s1[255];
    char s2[255] = "这是另外一个标题嘞";
    GetConsoleTitle(s1, 255);
    printf("获取控制台标题:%s\n", s1);

    SetConsoleTitle(s2);

    GetConsoleTitle(s1, 255);
    printf("获取控制台标题:%s\n", s1);
    return 0;
}

很简单的两个api(都不想写下去了,太简单了 ( ̄_ ̄|||))

其他的比如

在控制台中获取鼠标

#include <windows.h>  
#include <stdio.h>  

int main(void)
{



	// 获取标准输入输出设备句柄  
	HANDLE hOut = GetStdHandle(STD_OUTPUT_HANDLE);
	HANDLE hIn = GetStdHandle(STD_INPUT_HANDLE);

	CONSOLE_SCREEN_BUFFER_INFO bInfo;
	INPUT_RECORD	mouseRec;
	DWORD			res;
	COORD			crPos, crHome = { 0, 0 };

	printf("[Cursor Position] X: %2lu  Y: %2lu\n", 0, 0);	// 初始状态

	while (1)
	{
		ReadConsoleInput(hIn, &mouseRec, 1, &res);

		if (mouseRec.EventType == MOUSE_EVENT)
		{
			if (mouseRec.Event.MouseEvent.dwButtonState == FROM_LEFT_1ST_BUTTON_PRESSED)
			{
				if (mouseRec.Event.MouseEvent.dwEventFlags == DOUBLE_CLICK)
				{
					break;	// 左键双击 退出循环
				}
			}

			crPos = mouseRec.Event.MouseEvent.dwMousePosition;
			GetConsoleScreenBufferInfo(hOut, &bInfo);
			SetConsoleCursorPosition(hOut, crHome);
			printf("[Cursor Position] X: %2lu  Y: %2lu", crPos.X, crPos.Y);
			SetConsoleCursorPosition(hOut, bInfo.dwCursorPosition);

			switch (mouseRec.Event.MouseEvent.dwButtonState)
			{
			case FROM_LEFT_1ST_BUTTON_PRESSED:			// 左键 输出A
				FillConsoleOutputCharacter(hOut, 'A', 1, crPos, &res);
				break;		// 如果使用printf输出,则之前需要先设置光标的位置

			case RIGHTMOST_BUTTON_PRESSED:				// 右键 输出a
				FillConsoleOutputCharacter(hOut, 'a', 1, crPos, &res);
				break;

			default:
				break;
			}
		}
	}

	CloseHandle(hOut);  // 关闭标准输出设备句柄  
	CloseHandle(hIn);   // 关闭标准输入设备句柄  
	return 0;
}

注1:这个代码csdn很多人都有,放在这里是为了怕找不到
注2:不写基础的了,写的有点累,很多都是以后用不到,或者找一下就会的

设置_获取光标信息

#include <Windows.h>
#include <tchar.h> //支持通用字符集的一些操作头文件,使用双字节或者大字符集时可以不包含它
#include <stdio.h>

int _tmain() {


	HANDLE hOut = GetStdHandle(STD_OUTPUT_HANDLE);

	CONSOLE_CURSOR_INFO ifo = {60,true};
	SetConsoleCursorInfo(hOut, &ifo);

	system("pause");
	GetConsoleCursorInfo(hOut, &ifo);
	printf("%d,%d", ifo.dwSize,ifo.bVisible);

	return 0;
}

检测控制台的鼠标按键信息

    hStdin = GetStdHandle(STD_INPUT_HANDLE);
    if (hStdin == INVALID_HANDLE_VALUE)
        ErrorExit("GetStdHandle");

    // Save the current input mode, to be restored on exit.

    if (!GetConsoleMode(hStdin, &fdwSaveOldMode))
        ErrorExit("GetConsoleMode");

    // Enable the window and mouse input events.

    fdwMode = ENABLE_WINDOW_INPUT | ENABLE_MOUSE_INPUT;
    if (!SetConsoleMode(hStdin, fdwMode))
        ErrorExit("SetConsoleMode");

    // Loop to read and handle the next 100 input events.

    while (counter++ <= 100)
    {
        // Wait for the events.

        if (!ReadConsoleInput(
            hStdin,      // input buffer handle
            irInBuf,     // buffer to read into
            128,         // size of read buffer
