Question

Write program in 3*3 matrix multiplication using C language ( using by array )​

Answer 1

Answer:

C programming

Explanation:

#include <stdio.h>

#define N 4

void multiply(int mat1[][N], int mat2[][N], int res[][N])

{

int i, j, k;

for (i = 0; i < N; i++) {

for (j = 0; j < N; j++) {

res[i][j] = 0;

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

res[i][j] += mat1[i][k] * mat2[k][j];

}

}

}

int main()

{

int mat1[N][N] = { { 1, 1, 1, 1 },

{ 2, 2, 2, 2 },

{ 3, 3, 3, 3 },

{ 4, 4, 4, 4 } };

int mat2[N][N] = { { 1, 1, 1, 1 },

{ 2, 2, 2, 2 },

{ 3, 3, 3, 3 },

{ 4, 4, 4, 4 } };

int res[N][N]; // To store result

int i, j;

multiply(mat1, mat2, res);

printf("Result matrix is \n");

for (i = 0; i < N; i++) {

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

printf("%d ", res[i][j]);

printf("\n");

}

return 0;

}
