这么水的题居然错了好几次...主要几个点1.这个数有可能有小数点2.也是为什么我没AC...字符数组开小了...题目里没给大小我开了10000最后改成100000就AC了...

#include<cstdio>
#include<cstring>

char a1[100000],b[100000];
void quchu(char a[]){//去除末尾0的影响
int len,i;
len=strlen(a);
if(strstr(a,".")){
for(i=len-1;a[i]=='0';i--){
a[i]='\0';
len--;
}
}
if(a[len-1]=='.')
a[len-1]='\0';
}
int main(){

while(scanf("%s%s",a1,b)!=EOF){
quchu(a1);
quchu(b);
if(strcmp(a1,b)) printf("NO\n");
else printf("YES\n");
}
return 0;
}
