BZOJ-1000: A + B Problem

Hi, this is the very first Blog I wrote! Since I am an OIer, this is going to be about programming problems! Let’s begin with a simple one.

Problem Description: Given two numbers A, B, print the output of  A + B ( A,B ≤ ).

Sample Input: 
1 2
Sample Output:
3
Ideas: Emm.., I guess everyone knows how to do it, but it is a good thing to remember when to use long long.  

#include <iostream>
#include <cstring>
#include <string>
#include <vector>
#include <queue>
#include <map>
#include <set>
#include <stdio.h>
#include <fstream>
#include <cmath>
#include <stdlib.h>
#include <iomanip>
#include <algorithm>
using namespace std;
#define FAST_IO ios::sync_with_stdio(false);
typedef pair<int,int> pii;
typedef pair<long long,long long> pll;
typedef pair<double,double> pdd;
const int maxn = 1e6 + 10;


int main(){
    int a,b;
    cin>>a>>b;
    cout<<a + b<<endl;
    return 0;
}
