How can I create a 2D dynamic array using malloc() in C?

Question

I want to create a program that multiply two matrices which dimensions are two variables (i and j). I can't understand how to use malloc() to allocate the right amount of memory and how to use it.
I am developing using Visual Studio 2015.

Answer 1

int **arr = (int **)malloc(row * sizeof(int *));

for (i=0; i<row; i++)
arr[i] = (int *)malloc(column * sizeof(int));
