Question

I am new to C++, and am continuously told to use std::vector instead of new[].

I am trying to achieve this functionality, in where I know the size of the vector and want to assign to it randomly (not sequentially).

However, when running this, my program terminates with no error output, so I am stumped.

vector<string> v1;
v1.resize(2);
v1.insert(v1.begin() + 1, "world");
v1.insert(v1.begin() + 0, "world");

cout << v1.at(1) << endl;

Answer 1

Don’t give up, it’s easier than that

vector<string> v1(2);
v1[1] = "world";
v1[0] = "world";

cout << v1[1] << endl;

vector::insert is for when you want to add items to your vector, Not when you want to replace ones that are already there, vector::insert changes the size of the vector in other words.
