Matrix multiplication in c language: c program to multiply matrices (two dimensional array), this program multiplies two matrices which will be entered by the user. Firstly user will enter the order of a matrix. If the entered orders of two matrix is such that they can't be multiplied then an error message is displayed on the screen. You have already studied the logic to multiply them in Mathematics. Matrices are frequently used while doing programming and are used to represent graph data structure, in solving system of linear equations and many more

Algorithm: Multiplication of two matrix

Rule: Multiplication of two matrix is only possible if first matrix has size m X n and other matrix has size n x r. Where m, n and r are any positive integer.

Multiplication of two matrices is defined as

Where 1 ≤ i ≤ m and 1 ≤ j ≤ n

For example: Suppose two matrix A and B of size of 2 x 2 and 2 x 3 respectively
