Write a function to multiply two matrices a and b and save t

Write a function to multiply two matrices a and b and save the result in c. The header for the function is

const int N = 3;

void multiplyMatrix(const double a[][N], const double b[][N], double c[][N]);

Program needs to be written in C++. I will reward the the first correct answer! Thanks! :)

prompts user to enter matrix1 & matrix2 then multiplies them together through matrix multiplication.

Solution

#include<iostream.h>

#include<conio.h>

Const int N=3;

Void multiplyMatrix(const double a[][N], const double b[][N], const double c[][N])

{

    cout<<\"Multiplying two matrices...\ \";

        for(i=0; i<3; i++)

        {

               for(j=0; j<3; j++)

               {

                       sum=0;

                       for(k=0; k<3; k++)

                       {

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

                       }

                       c[i][j] = sum;// storing the result of the two matrices multiplication into third matrix

               }

        }

        cout<<\"\ Multiplication of two Matrices : \ \";

        for(i=0; i<3; i++)

        {

               for(j=0; j<3; j++)

               {

                       cout<<c[i][j]<<\" \";

               }

               cout<<\"\ \";

        }

}

void main()

{

        clrscr();

        int a[3][3], b[3][3], c[3][3], sum=0, i, j, k;

        cout<<\"Enter first matrix element (3*3) : \"; //reading first matrix elements

        for(i=0; i<3; i++)

        {

               for(j=0; j<3; j++)

               {

                       cin>>mat1[i][j];

               }

        }

        cout<<\"Enter second matrix element (3*3) : \";// reading second matrix elements

        for(i=0; i<3; i++)

        {

for(j=0; j<3; j++)

               {

                       cin>>mat2[i][j];

               }

        }

       

       multiplyMatrix(const a, const b, const c) //multiplication of two matrices

}

output:
