2324 - 乘法运算

从键盘读入2个100以内的正整数，进行乘法运算并以竖式输出。

例如，输入：<span>89 13&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; </span>又如，输入：<span>16 8</span>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;输出：<span>&nbsp; &nbsp; &nbsp; &nbsp;89 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;</span>输出：<span>&nbsp; &nbsp; &nbsp;16</span>

Input

每个测试文件只包含一组测试数据，每组输入数据为两个100以内的正整数，之间由一个空格分隔。

Output

对于每组输入数据，输出两个整数进行乘法运算的竖式。为了简单起见，只需从上到下输出竖式里面的数即可，具体格式见样例输出。

		if(j!=1)
		    printf("%d\n",count);
		printf("\n");
	return 0;
}

Solution C++

#include<stdio.h>
int main()
{
	int a,b,s,k,res;
	int len = 0; 
	scanf("%d%d",&a,&b);
	char buf[10];
	k = a;
	while(k>0)
		len++,k/=10;
	sprintf(buf,"%%0%dd\n",len);
	k = b;
	printf("%d\n%d\n",a,b);
	while(k>0)
	{
		s=k%10;
		printf(buf,s*a);
		k/=10;
	}
	if(b>=10)
		printf("%d\n",a*b);
	
	//printf("%d",5);
	return 0;
