如何从 Vector 中删除某个部分？

Question

#include <iostream>
#include <string>
#include <vector>

using namespace std;

vector <string> items = {"Sword\n", "Shield\n", "Brass Helmet\n", "Iron Breastplate\n"};

void inventory(){

     for (int i = 0; i < items.size(); i++){
          cout<<items[i];
     }
}

int main(){
    inventory();
    return 0;
}

I'm familiar with the commands vector.pop_back() which deletes the last in the vector, and vector.clear() which deletes the entire vector.

How would I go about deleting items[0] or deleting the portion items[0] - items[3]?

As the guys told you, you can use the erase function. You can use it to erase a specific element from the vector or delete a portion of it.

items.erase(items.begin());
items.erase(items.begin(), items.begin() + 3);
