A simplified version of the matrix multiplication for 2x2
matrices can be represented as: The answer to this
question should be a C program structured as a helper
(user-defined) function only (do not write the preprocessor
directives not the main program). Your function named
mult performs the 2x2 matrix multiplication and displays on
the screen the resulting matrix in conventional matrix
format (2 rows / 2 columns). All variables are integers. You
must use 2-D arrays only for this question and name them
mat1, mat2 and mat3. No other variables are permitted
(except i and j as loop control variables if needed). Do not
use dynamically allocated variables. Your function needs
to work only with 2x2 matrices. Penalties will be applied for
Solution
multi.c
#include <stdio.h>
void mult (int mt1[][2], int mat2[][2], int mat3[][2]);
int main()
{
int mat1[2][2], mat2[2][2], mat3[2][2],i,j;
/* Storing elements of first matrix. */
printf(\"\ Enter elements of matrix 1:\ \");
for(i=0; i<2; i++)
