while(c=='y'|| c=='Y')        scanf("%d",&year);
这个死循环

这贴是我发的，有请高手们帮我看一下是不是对的，刚才发帖时妄说了

char c='y';
    while(c=='y'|| c=='Y')
        scanf("%d",&year);
//这三句存在问题，死循环。
char c='y';
    while(c=='y'|| c=='Y')
       {
             scanf("%d",&year);
/你是不是少写了一个花括弧

#include<stdio.h>
void main()
{
    int year,x;//n这个变量，没有调用吧
    char c='y';
    while(c=='y'|| c=='Y')

        scanf("%d",&year);
        if(year>0)
