先讲一下这个画板是这样用的

1-7是颜色

8停止运行

9是保存

0是调出上一次的存档

先放个头文件

#include <bits/stdc++.h>
#include <conio.h>
#include <windows.h>
using namespace std;

我那乱七八糟的变量名可能要花很久才能看懂......

int a[2000],b[2000][2000],x,y,z,i=0,w,s;

接着定义函数

我也不知道咋讲,看代码吧

void ColorChoose(int color)   //颜色选择函数

{
    switch(color)

    {

           case 1:               //天蓝色(我的喵颜色)

            SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_GREEN|FOREGROUND_BLUE);
			cout<<"█";
            break;

        case 2:               //绿色

            SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_GREEN);    
			cout<<"█";
            break;

        case 3:               //黄色

            SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_RED|FOREGROUND_GREEN);
			cout<<"█";
            break;

        case 4:               //红色

            SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_RED);
			cout<<"█";
            break;

        case 5:               //紫色

            SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_RED|FOREGROUND_BLUE);
			cout<<"█";
            break;

        case 6:               //白色

            SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_RED|FOREGROUND_BLUE|FOREGROUND_GREEN);
			cout<<"█";
            break;

        case 7:               //深蓝色

            SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_BLUE);
            cout<<"█";
            break;

    }

}

接着就是主函数了

int ch;
while (z!=1){
    if (_kbhit()){//如果有按键按下，则_kbhit()函数返回真
        ch = _getch();//使用_getch()函数获取按下的键值
    }
}

ch是用来识别你按下的键的

接着下面就是完整的代码啦

#include<bits/stdc++.h>
#include <conio.h>
#include <windows.h>
using namespace std;
int a[2000],b[2000][2000],z,i=0,w,s;
void ColorChoose(int color)   //颜色选择函数

{
    switch(color)

    {

           case 1:               //天蓝色(我的喵颜色)

            SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_GREEN|FOREGROUND_BLUE);
			cout<<"█";
            break;

        case 2:               //绿色

            SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_GREEN);    
			cout<<"█";
            break;

        case 3:               //黄色

            SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_RED|FOREGROUND_GREEN);
			cout<<"█";
            break;

        case 4:               //红色

            SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_RED);
			cout<<"█";
            break;

        case 5:               //紫色

            SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_RED|FOREGROUND_BLUE);
			cout<<"█";
            break;

        case 6:               //白色

            SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_RED|FOREGROUND_BLUE|FOREGROUND_GREEN);
			cout<<"█";
            break;

        case 7:               //深蓝色

            SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE),FOREGROUND_INTENSITY|FOREGROUND_BLUE);
            cout<<"█";
            break;

    }

}

int main(){
	int ch;
    while (z!=1){
        if (_kbhit()){//如果有按键按下，则_kbhit()函数返回真
            ch = _getch();//使用_getch()函数获取按下的键值
            if(ch==49){ ColorChoose(1);
            a[i]=49;
            i++;
			}else if(ch==50){ ColorChoose(2);
			a[i]=50;
			i++;

			}else if(ch==57){
			ofstream fout("D:/画板输出.txt");
			fout<<i<<" ";
			s=i;
			i=0;
			while(i<s){
				if(a[i]==0) i++;
				fout<<a[i]<<" ";
				i++;
		}
			fout.close();
			}else if(ch==48){
			ifstream fin("D:/画板输出.txt");
			fin>>i;
			s=i;
			i=0;
			while(i<s){
				fin>>a[i];
				i++;
			}
			i=0;
			while(i<s){
			if(a[i]==0) i++;
			if(a[i]==49){ ColorChoose(1);
			}else if(a[i]==50){ ColorChoose(2);

			}
    }
}
	return 0;
}

不喜勿喷

不知道你们有没有学C++呢？
