C++) 재미로 해본 로또 번호 출력하기 (Feat. Insertion sort && Vector)

- 길몽을 꾸었길래 공부할 겸 만들기 

#include <iostream>

#include <vector>

#include <cstdlib>

#include <ctime>

using namespace std;

int main()

{

    srand((unsigned)(time(NULL)));

    vector<int> v1;

    for (int i = 0; i < 6; i++)

    {

        int a = rand() % 45 + 1;

        v1.push_back(a);

    }

    // Insertion sort

    for (int i = 1; i < v1.size(); i++)

    {

        int key = v1[i];

        int j = i - 1;

        while (j >= 0 && v1[j] > key)

        {

            v1[j + 1] = v1[j];

            j -= 1;

        }

        v1[j + 1] = key;

    }

    // Printing the sorted vector

    cout << "Sorted vector in ascending order: ";

    for (int i = 0; i < v1.size(); i++)

    {

        cout << v1[i] << " ";

    }

    cout << endl;

    return 0;

}
