Matrix multiplication using C

 

Hey guys once again welcome to the Decoders blog, I hope you all are doing well and today I'm present with another logic but this time with something different it is a C logic which will help us to get the multiplication of given two matrices using arrays in C 

Here's the code which you can go through...........

//Matrix multiplication

#include<stdio.h>

int main()

{

    int a[3][3],b[3][3],c[3][3];

    int i,j,k;

    printf("Enter the value of the matrix a:\n");

    //Storing the values for the matrix [A]

    for(i=0;i<3;i++)

    {

        for(j=0;j<3;j++)

        {

            scanf("%d",&a[i][j]);

        }

    }

    printf("Enter the value of the matrix a:\n");

    //Storing the values for the matrix [B]

    for(i=0;i<3;i++)

    {

        for(j=0;j<3;j++)

        {

            scanf("%d",&b[i][j]);

        }

    }

    //Displaying the matrix [A]

    printf("Matrix A:\n");

    for(i=0;i<3;i++)

    {

        for(j=0;j<3;j++)

        {

            printf("%d\t",a[i][j]);

        }

        printf("\n");

    }

    //Displaying the matrix [B]

    printf("Matrix B:\n");

    for(i=0;i<3;i++)

    {

        for(j=0;j<3;j++)

        {

            printf("%d\t",b[i][j]);

        }

        printf("\n");

    }

    //Logic for storing the values of the matrix [C]

    for(i=0;i<3;i++)

    {

        for(j=0;j<3;j++)

        {

            c[i][j]=0;

            for(k=0;k<3;k++)

            {

                c[i][j] += a[i][k]*b[k][j];

            }

        }

    }

    //Displaying the values of the matrix [C]

    printf("Matrix C:\n");

    for(i=0;i<3;i++)

    {

        for(j=0;j<3;j++)

        {

            printf("%d\t",c[i][j]);

        }

        printf("\n");

    }

    return(0);

}
