벡터 삭제하는 몇가지 방법

1. input 값

#include <iostream>
#include <vector>
#include <algorithm>

using namespace std;

int main() {
	// index로 하나삭제 
	vector<int> myvec = { 1,2,3,4,5,6 };
	myvec.erase(myvec.begin() + 1);
	for (int i = 0; i < myvec.size(); i++) {
		cout << myvec[i] << ",";
	}
	cout << endl;

	// index로 범위삭제
	myvec = { 1,2,3,4,5,6 };
	myvec.erase(myvec.begin() + 3, myvec.begin() + 5);
	for (int i = 0; i < myvec.size(); i++) {
		cout << myvec[i] << ",";
	}
	cout << endl;

	// 값으로 삭제
	myvec = { 1,2,3,3,5,6 };
	myvec.erase(remove(myvec.begin(), myvec.end(), 3), myvec.end());
	for (int i = 0; i < myvec.size(); i++) {
		cout << myvec[i] << ",";
	}
	cout << endl;

	return 0;
}

 

2. output값

1,3,4,5,6,
1,2,3,6,
1,2,5,6,
