C++ Equivalent to VB Arrays

Since it is becoming increasingly common to use std::vector instead of arrays in C++, we give examples of both conversions below. (VB to C++ Converter converts to std::vector by default).

Unsized Array

VB C++
Dim myArray() As Integer = Nothing //as a vector:
std::vector<int> myArray;

//as an array:
int *myArray = nullptr;

Sized Array

VB C++
Dim myArray(1) As Integer //as a vector:
std::vector<int> myArray(2);

//as an array:
int *myArray = new int[2];

Access Array Element

VB C++
x = myArray(0) x = myArray[0];

Jagged Array

VB C++
Dim myArray(1)() As Integer //as a vector:
std::vector<std::vector<int>> myArray(2);

//as an array:
int **myArray = new int*[2];

Rectangular Array

VB C++
Dim myArray(1, 2) As Integer //as a vector:
std::vector<std::vector<int>> myArray = RectangularVectors::ReturnRectangularIntVector(2, 3);

    {
        std::vector<std::vector<int>> newVector(size1);
        for (int vector1 = 0; vector1 < size1; vector1++)
        {
            newVector[vector1] = std::vector<int>(size2);
        }

        return newVector;
    }
};

//as an array:
int **myArray = new int*[2][3];
