hard to believe, but true!.txt

以前ACM在哈工程HRBEU做的一些简单题目

#include <iostream.h>
#include <stdlib.h>
#include <string.h>

int main()
{
	char s[50],t;
	long sum,x,y;
	int i,j;
	while(cin>>s)
	{
		j=strlen(s);
		for(i=j-1;i>=j/2;i--)
		{t=s[i];s[i]=s[j-i-1];s[j-i-1]=t;}
        sum=atol(s);
		i=0;
        while(s[i]!='=')i++;
		i++;
		y=atol(s+i);
		while(s[i]!='+')i++;
		i++;
		x=atol(s+i);
		if(x+y==sum)cout<<"True"<<endl;
		else cout<<"False"<<endl;
		if(x==0&&y==0&&sum==0)break;
	}
	return 0;
}
