A$54-$ WAP to find the product of given matrix. in C

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

Final Result :

Result $=$ A $*$ B

$123111$

R$=123$ x $222$

$123333$

R$1=[(1*1)+(2*2)+(3*3)(1*1)+(2*2)+(3*3)(1*1)+(2*2)+(3*3)]$
