控制生成的数字为0和1两个数

st\[i\].ch = rand()%(49-47)+48;

gotoxy函数确定ch在屏幕中出现的位置，set\_color函数修改ch的颜色,最后输出设置好的ch

gotoxy(st\[i\].x,st\[i\].y);  
set\_color(0x2);  
putchar(st\[i\].ch);

#include<stdio.h>
    #include<time.h>
    #include<windows.h>
    typedef struct
    {
    	int x,y;
    	char ch;
    }STU;
    STU st[100];
    //出现位置   
    
    void gotoxy(int x, int y)  
    {  
        HANDLE hout;  
        COORD pos;  
        pos.X = x;  
        pos.Y = y;  
    	
        hout = GetStdHandle(STD_OUTPUT_HANDLE);  
        SetConsoleCursorPosition(hout, pos);  
    }  
    
    /*隐藏光标*/  
    void show_cursor(int hide)  
    {  
        CONSOLE_CURSOR_INFO cciCursor;  
        HANDLE hout;  
    	
        hout = GetStdHandle(STD_OUTPUT_HANDLE);  
        if(GetConsoleCursorInfo(hout, &cciCursor))  
        {  
            cciCursor.bVisible = hide;  
            SetConsoleCursorInfo(hout, &cciCursor);  
        }  
    }  
    
    /*设置颜色*/  
    void set_color(int color)  
    {  
    	
        SetConsoleTextAttribute(GetStdHandle(STD_OUTPUT_HANDLE), color);  
    }  
    
    
    main()
    {
    	int i,j;
    	show_cursor(0);
    	srand(time(NULL));
    	//初始化结构体
