Invalid operands of types long long int and unresolved overloaded function type to binary operator+

Question

I am writting a simple experimental code in c++. But not able to figure out why is it giving me this error. Below is my code:

#include <bits/stdc++.h>
using namespace std;

int main(){
    long long m = 100006L;
    long long ans = 243343435L;
    long long inv = 123455677L;
    long long x = 0L;
    bool succcess = false;

    for(long long p = 1L; p<10000000;p++){
        if((m*p + ans) % inv == 0 ){
            succcess = true;
            x = ((m*p) + remainder) / inv;
            break;
        }
    }

    return 0;   
}

你没有声明命名一个局部变量remainder ，所以编译器认为你是指标准的remainder()由于包含的是非标准的功能（即可见bits/stdc++.h头，它包括一切和厨房水槽），因此出现奇怪的错误消息（ remainder有几个重载，因此名称本身就是“未解析的函数类型”）。
