Question

hdu 2060 这题是不是有问题。求大牛帮忙看看这么写，为什么会WA？

#include<iostream>
using namespace std;

int main()
{
int T,s,max_num,count,i,c;
scanf("%d",&T);
while(T--)
{
c=7;
scanf("%d %d %d",&count,&s,&max_num);
if(count>6)
s+=8*(count-6)+27;
else
s+=(15-count)*count/2;
if(s>=max_num)
printf("YES\n");
else
printf("NO\n");
}
return 0;
}

#include<iostream>
using namespace std;

int main()
{
int T,s,max_num,count,i,c;
scanf("%d",&T);
while(T--)
{
c=7;
scanf("%d %d %d",&count,&s,&max_num);
if(count>6)
s+=8*(count-6)+27;
else
s+=(15-count)*count/2;
if(s>=max_num)
printf("Yes\n"); // Yes, not YES
else
printf("No\n"); // The same
}
return 0;
}

Answer 2

头文件使用#include <stdio.h>
变量i，c多余
