Started my adventure with programing fairly recently so please dont be too harsh.
I planed to create a 2D array that is filled with 0 (ultimately I will fil it with various numbers but not important right now). The size of array should be input by user. So I use pointers. I found some of the examples here on StackOverflow, tried using it and the code was buggy - sometimes it worked, sometimes it didnt.
It never works when rows = columns. It also never works when with second iteration of code You switch columns with rows eg:
Run code first time - call rows 3, columns 9, end program.
Run code second time - call rows 9, columns 3 - no execution.
Source I was using:Declaring a pointer to multidimensional array and allocating the array
#include <iostream>
using namespace std;
void dynamicArray(int** array, int columns, int rows)
{
cout << " i am working" << endl;
for (int i=0; i<rows ; ++i)
{
for (int j=0; j <columns ;j++)
{
array [columns][rows] = 0;
cout << array [columns][rows] << " " << flush ;
}
cout << endl;
}
}
int main() {
int columns = 0;
int rows = 0;
cout << " state the number of rows: " << endl;
cin >> rows;
cout << " state the number of columns: " << endl;
cin >> columns;
int **array = new int*[rows];
for(int i = 0; i < rows; ++i)
{
array[i] = new int[columns];
}
dynamicArray(array, columns, rows);
for(int l = 0; l < rows; l++)
delete [] array[l];
delete [] array;
return 0;
}
I quite frankly have no idea how to fix it, hope for your help
BR, Mark
