How to add a certain amount of elements in a vector without using a loop C++

I'm trying to add 100 elements in a vector located inside a class, but I can't use a for loop because the vector is defined outside of a function. Is there any way for me to add the values without having to manually list them?

class Player
{
    vector<bool> able; // set 10 values to 0
    vector<bool> tertiary; // set 100 values to 0
    
    void other_funcs()
    {
        //stuff
    }
}

Values of bool should really be trueor false although 0 will convert to false.

If you want to set your members as indicated in your code you can do that this way:

class Player
{
    std::vector<bool> able = std::vector<bool>(10, false);
    std::vector<bool> tertiary = std::vector<bool>(100, false);

    void other_funcs()
    {
    }
};

The statement std::vector<bool>(10, false) constructs a vector with 10 elements all set to false.

Use std::fill:

std::fill(able.begin(), able.begin() + 10, 0);

Make sure your vector has enough space to do so:

std::vector<bool> able(10);
