Project 1: C language example code implementing matrix multiplication. It contains three functions. 2D array creation function Generated array output function matrix multiplication function

#include <stdio.h>
#include <stdlib.h>
int **array;

int **create2DArray(int row, int col)
{
    int **array = malloc(row * sizeof(int *));
    for (int i = 0; i < row; i++)
    {
        array[i] = malloc(col * sizeof(int));
    }
    return array;
}

int **get2DArray(int row, int col)
{
    int **array = create2DArray(row, col);

    for (int i = 0; i < row; i++)
    {
        for (int j = 0; j < col; j++)
        {
            array[i][j] = rand() % 10;
        }
    }
    return array;
}
