16年只有两道题。

1.给定一个数n,将这个数的各位顺序颠倒，成为逆序数m。

例如1234的逆序数是4321.

如果m是n的k倍（k为整数），那么输出n*k=m

例如输入1089

输出1089*9=9801

如果m不是n的整数倍，那么输出n和m的逆序数

例如输入1234

输出1234 4321

例如输入23200

输出23200 00232

已知输入开头不包括多余的零

using namespace std;
int max(int x,int y){

}


int main(int argc, char* argv[])
{
	int n1,n2;
	int tmp;
	char str1[100]={0};
	char str2[100]={0};
	scanf("%d",&n1);
	//cout<<n1<<endl;

	itoa(n1,str1,10);
	//cout<<str1<<endl;
	reverse(str1,str1+strlen(str1));
	//cout<<str1<<endl;
	n2=atoi(str1);
	//cout<<n2<<endl;
	if(n2%n1==0){
		printf("%d*%d=%s",n1,n2/n1,str1);
	}else{
		printf("%d %s",n1,str1);

	}

	return 0;
}

2.给一个c语言的enum定义语句，输出enum中规定的各项及其对应的数值。

输入 enum BOOL{true,false};

输出

true 0

false 1

输入 enum date{JAN=1,FEB,MAR,APR,MAY,JUN,JULY,AUG,SEP,OCT,NOV,DEC,MON=1,TUE,WED,THU,FRI,SAT,SUN,found=1949};

输出

JAN 1

FEB 2

MAR 3

APR 4

MAY 5

JUN 6

JULY 7

AUG 8

SEP 9

OCT 10

NOV 11

DEC 12

MON 1

TUE 2

WED 3

THU 4

FRI 5

SAT 6

SUN 7

found=1949
