# Multiplication of two matrix in c

C program for Two Matrix Multiplication. Here mentioned other language solution.

``````// Include header file
#include <stdio.h>
#define ROW 3
#define COL 3
/*
C program for
Two matrix multiplication
*/
// Display the element of given 2d matrix
void printRecord(int matrix[][COL])
{
printf("  --------------\n");
// Iterate the row element
for (int i = 0; i < ROW; i++)
{
// Iterate the column element
for (int j = 0; j < COL; j++)
{
// Display element value
printf("  %d", matrix[i][j]);
}
printf("\n");
}
printf("\n");
}
void multiplication(int a[][COL], int b[][COL])
{
// This matrix are store the result of multiplication
int result[ROW][COL];
for (int i = 0; i < ROW; i++)
{
for (int j = 0; j < COL; j++)
{
// Set the initial value of new matrix element
result[i][j] = 0;
for (int k = 0; k < ROW; k++)
{
// Multiply matrix A [i] row and [k] columns to
// the Matrix B [k] columns and [j] rows.
result[i][j] += a[i][k] * b[k][j];
}
}
}
printf("  Matrix A\n");
// Print element of matrix x
printRecord(a);
printf("  Matrix B\n");
// Print element of matrix y
printRecord(b);
printf("  Matrix [(A) x (B)]\n");
// Display resultant matrix
printRecord(result);
}
int main()
{
// Define matrix A
int a[][COL] = {
{1 , 2 , 3} ,
{6 , 1 , 2} ,
{5 , 4 , 3}
};
// Define matrix B
int b[][COL] = {
{3 , 1 , 3} ,
{1 , 1 , 2} ,
{2 , 2 , 3}
};
multiplication(a, b);
return 0;
}``````

Output

``````  Matrix A
--------------
1  2  3
6  1  2
5  4  3

Matrix B
--------------
3  1  3
1  1  2
2  2  3

Matrix [(A) x (B)]
--------------
11  9  16
23  11  26
25  15  32
