[1938] :  아주 간단한 계산기

#include <iostream>
using namespace std;

int main(void){
    int num1, num2;
    cin >> num1 >> num2;
    cout << num1 + num2 << endl;
    cout << num1 - num2 << endl;
    cout << num1 * num2 << endl;
    cout << num1 / num2 << endl;
    return 0;
}

[2025] : N줄 덧셈

#include <iostream>
using namespace std;

int main(void){
    int N, sum = 0;
    cin >> N;
    for(int i = 0; i < N; i++)
        sum += (i + 1);
    cout << sum;
    return 0;
}

[2027] :  대각선 출력하기

#include <iostream>

using namespace std;

int main(void){
    for(int i = 0; i < 5; i++){
        for(int j = 0; j < 5; j++){
            if(i == j) cout << "#";
            else cout << "+";
        }
        cout << endl;
    }
    return 0;
}

[2029] : 몫과 나머지 출력하기

#include <iostream>
using namespace std;
int main(void){
    int N, num, dv;
    cin >> N;
    int ans[N][2];
    for(int i = 0; i < N; i++){
        cin >> num >> dv;
        ans[i][0] = num / dv;
        ans[i][1] = num % dv;
    }
    for(int j = 0; j < N; j++)
        cout << "#" << j + 1 << " " << ans[j][0] << " " << ans[j][1] << endl;
    return 0;
}

[2043] : 서랍의 비밀번호

#include <iostream>
using namespace std;
int main(void){
    int P, K;
    cin >> P >> K;
    cout << P - K + 1;
    return 0;
}
