哪里错了 该怎么修改？

Question

#include<stdio.h>
int main(){
    int a,b;
    scanf("%d %d",&a,&b);
    int s=1000;double t=0;
    int d=5*a-6*b;
    if(d<=0) printf("It is sad.");
    else{
        a=a-b;
    while(s){
        if(s/a<=5){
            t+=1.0*s/a;
            s=0; 
        }else{
            t+=6;
            s-=d;    
        } 
     printf("%.2lf",t);
    }return 0;
    }
    
}

输出的结果确是这样的

Answer 1

printf语句放到return 0前面，不要放在while循环中
