C PROGRAM need same output

1 - WAP to find the product of given matrix.

Description:

Read no.of rows and columns for 2 arrays from user and allocate the memory dynamically using malloc or calloc (Assume Matrix A and Matrix B).

Read the Matrix A and B from user.

Find the product for matrix A with matrix B amd store the result in Matrix R.

Let say Name of the matrix is A and no. Of rows = columns = 3.

Matrix A

1	2	3
1	2	3
1	2	3

Matrix B

1	1	1
2	2	2
3	3	3

Final Result :

Result = A * B

1 2 3 1 1 1

R= 1 2 3 x 2 2 2

1 2 3 3 3 3

R1 = [(1 * 1) + (2 * 2) + (3 * 3) (1 * 1) + (2 * 2) + (3 * 3) (1 * 1) + (2* 2) + (3 * 3)]

Result matrix is

14	14	14
14	14	14
14	14	14

Pr-requisites:

2D Arrays / Pointers.

DMA.

Objective:

To understand the concept of

DMA

Double Pointers / 2D array.

Inputs:

No.of rows, Columns and row * column values for the matrix A and matrix B.

Sample output: Test case1: Enter number of rows : 3 Enter number of columns : 3 Enter values for 3 x 3 matrix : 1 2 3 1 2 3 1 2 3 Enter number of rows : 3 Enter number of columns : 3 Enter values for 3 x 3 matrix : 1 1 1 2 2 2 3 3 3 Product of two matrix : 14 14 14 14 14 14 14 14 14

Test case 2: Enter number of rows : 3 Enter number of columns : 3 Enter values for 3 x 3 matrix : 1 2 3 1 2 3 1 2 3 Enter number of rows : 2 Enter number of columns : 3 Matrix multiplication is not possible
