matrix multiplication: code is only printing matrices but no multiplication product

Code:

#include<stdio.h>
#include<stdlib.h>


int mallocMatrix (int ***matrix, int A, int B) {
    int i;
    *matrix=(int**)malloc(sizeof(int*)*B);
        for(i=0;i<B;i++)
            (*matrix)[i]=(int*)malloc(sizeof(int)*A);
};

void getMatrix (int ***matrix, int A, int B) {
    int i, j;
    for(i=0;i<B;i++)
    {
        for(j=0;j<A;j++)
            {
                 printf("Matrix[%d][%d]: ",i+1,j+1);
                 scanf("%d", &(*matrix)[i][j]);
            }
        }
};

void putMatrix (int ***matrix, int A, int B) {
    int i, j;
    printf ("\n");
    for(i=0;i<B;i++)
    {
        for(j=0;j<A;j++)
        {
            printf ("%d ", (*matrix)[i][j]);
        }
    printf ("\n");
    }
};

int main(){
    int **matrix;
    int **matrix_2;
    int **matrix_3;
    int n, m, p, d, temp;

    printf ("[1st matrix] number of columns:");
    scanf ("%d", &n);
    printf ("[1st matrix] number of rows:");
    scanf ("%d", &m);

        mallocMatrix (&matrix, n, m);
        getMatrix (&matrix, n, m);

    printf ("[2nd matrix] number of columns:");
    scanf ("%d", &p);
    printf ("[2nd matrix] number of rows:");
    scanf ("%d", &d);

        if (n==d)
        {
            mallocMatrix (&matrix_2, p, d);
            getMatrix (&matrix_2, p, d);
        }
        else
        {
            printf ("Number of columns in 1st matrix must equal number of rows in the 2nd matrix");
            return -1;
        }

    putMatrix (&matrix, n, m);
    putMatrix (&matrix_2, p, d);

    mallocMatrix (&matrix_3, m, p);

    /* matrix multiplication */

    int i, j, k;
    for(i = 0; i < m; i++)
    {
        for(j = 0; j < p; j++)
        {
            for(k = 0; k < m; k++)
            {
                matrix_3[i][j] = (matrix_3[i][j] + (matrix[i][k] * matrix_2[k][j]));
            }
        }
