#include<bits/stdc++.h>
using namespace std;
int main(){
    long long a,b,x,sum;
    cin>>a>>b;
    x=a-b;
    if(x%100!=0){
        sum=int(x/100)+1;
        cout<<sum;
    }
    else{
        sum=x/100;
        cout<<sum;
    }
}

最后去了int就过了

#include<bits/stdc++.h>
using namespace std;
int main(){
    long long a,b,x,sum;
    cin>>a>>b;
    x=a-b;
    if(x%100!=0){
        sum=x/100+1;
        cout<<sum;
    }
    else{
        sum=x/100;
        cout<<sum;
    }
}

那位DALAO解释一下？第一个有用回答给关
