How to create a void vector

November 7, 2022

I’m new to c++ and I was wondering why this part of my code was not working

void fill 2DVector (vector<int> someVec, int i)
{
    for (auto& row: someVec)
    row.fill(i) ;
}

>Solution :

There are several problems with the code.

First there should be an underscore or some other valid character between fill and 2DVector instead of a space.

Second, row is an int which is a built in type and doesn’t have member functions(like fill).

//-------v--------------------------------------->added underscore. You can add other valid character except space
void fill_2DVector (vector<int> someVec, int i)
{
    for (auto& row: someVec)
        cout << row;  //you can print row which is an it 
}
