Visual Studio Code c++ code compiles, but there is no console output

Question

My C++ code compiles and runs, but no output is printed to the console. If I run this exact code on an online c++ compiler it works as expected. This problem occurred when I started adding everything related to arrays (the functions and so on) so the problem might be there as It was working fine before that. Also, I'm using GNU GCC Compiler for VSC and extra parameters when launching the exe. --rand to generate random numbers in the array. I've been trying to find the answer now for this for hours, and can't figure it out.

#include<iomanip>
#include<limits>

int getNumber()
{
    int x;
    while(!(std::cin >> x)){
        std::cin.clear();
        std::cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
        std::cout << "Wrong Input. Try Again: ";
    }
    return x;
}

void outputArray(int rows,int columns,float array[]) 
{
    int i,j;
    for (i = 0; i < rows; i++){
        for (j = 0; j < columns; j++) 
        {
            std::cout << (i+1) <<" "<< array[i*columns+j] << std::endl;
        }
    }
}

                array[i] = max * ((float)rand()/(float)RAND_MAX) * 2 - max;
