Code Explanation :

In this example you'll learn to use two-dimensional arrays to add two matrices during C programming.

The user is asked to enter in this program for the number of rows r and the columns c. The user is then asked to enter the elements of the two matrices (order r*c).

We then inserted the corresponding two-matrix elements and stored them in another matrix (two-dimensional array). The result is eventually written onto the board.

We are going to represent this code into algorithm and flowchart.


STEP 1 : Start

STEP 2 : Declare  array  a[10][10],  b[10][10],  sum[10][10]  with r, c,
        i, j and k

STEP 3 : Read r and c

STEP 4 : Repeat this step until i < r
        STEP 4.1 : Repeat this step until j < c
                STEP 4.1.1 : Read for a[i][j]
                STEP 4.1.2 : j++
        STEP 4.2 : i++

STEP 5 : Repeat this step until i < r
        STEP 5.1 : Repeat this step until j < c
                STEP 5.1.1 : Read for b[i][j]
                STEP 5.1.2 : j++
        STEP 5.2 : i++
STEP 6 : Repeat this step until i < r
        STEP 6.1 : Repeat this step until j < c
                STEP 6.1.1 : sum[i][j] = a[i][k] + b[k][j]
                STEP 6.1.2 : j++
        STEP 6.2 : i++

STEP 7 : Repeat this step until i < r
        STEP 7.1 : Repeat this step until j < c
                STEP 7.1.1 : Print sum[i][j] with tab
                STEP 7.1.2 : j++
        STEP 7.2 : Print "n" for line break
        STEP 7.3 : i++

STEP 8 : End
