整理一些常用算法--回文判断

#include <stdio.h>

int main()
{
	int num;
	int tmp;
	int rem = 0;
	int reverse = 0;
	printf("请输入一个正整数\n");
	scanf("%d", &num);
	tmp = num;
	while (tmp != 0) 
	{
		rem = tmp % 10;
		reverse = 10 * reverse + rem;
		tmp /= 10;
	}
	
	if (reverse == num)
	{
		printf("该整数是回文!\n");
	}
	else
	{
		printf("该整数不是回文!\n");
	}
	return 0;
}
