C program to multiply two matrices without function
Code Explanation :
In this example, we are going to multiply two matices that are given by user without function.
In this program, user input matrix row and column and give matrix elements and then after we multiply these two matrices.
Here we have uses
for loop to read and multiply matrix.
This is not the better way to write code. This is simplified using function.
It is better to do this example using function because we use
for loop for many times. That code, We have not to be used in
We are going to represent this code into algorithm and flowchart.
STEP 1 : Start
STEP 2 : Declare array a, b, mul 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 : mul[i][j] = 0
STEP 6.1.2 : Repeat this step until k < c
STEP 18.104.22.168 : mul[i][j] += a[i][k] * b[k][j]
STEP 22.214.171.124 : k++
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 b[i][j] with tab
STEP 7.1.2 : j++
STEP 7.2 : Print "n" for line break
STEP 7.3 : i++
STEP 8 : End
