ABC050 APG4b Addition and Subtraction Easy

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

int main(){
  int a,b,ans=0;
  char x;
  cin >> a >> x >> b;
  if(x=='+'){
    ans = a+b;
  }else if(x=='-'){
    ans = a-b;
  }else{
    cout << "Operator error" << endl;
  }
  
  cout << ans << endl;
}

一般的にEasyなこの問題も私は躓きました（笑）とりあえずAtCoder練習し始めて4日目!!3日坊主は乗り越えた!
