小O的数字 （C语言代码）

解题思路:

注意事项:

参考代码:

#include<stdio.h>
void Paint(unsigned long  a,int i)
{
    char zeno[5][4]={"***","* *","* *","* *","***"};
    char one[5][4]={"  *","  *","  *","  *","  *"};
    char two[5][4]={"***","  *","***","*  ","***"};
    char three[5][4]={"***","  *","***","  *","***"};
    char four[5][4]={"* *","* *","***","  *","  *"};
    char five[5][4]={"***","*  ","***","  *","***"};
    char six[5][4]={"***","*  ","***","* *","***"};
    char seven[5][4]={"***","  *","  *","  *","  *"};
    char eight[5][4]={"***","* *","***","* *","***"};
    char nine[5][4]={"***","* *","***","  *","***"};
 	switch(a)
	{
		case 0:
				printf("%s",zeno[i]);
		break;
