Multiplication of two matrices

#include <stdio.h>

int main (){

int a[3][3] = {{1,2,3},{4,5,6},{7,8,9}};

int b[3][3] = {{1,3,4},{5,6,7},{1,7,9}};

int c[3][3] = {0};

int k = 2;

for(int i = 0 ; i < 3; i++){

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

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

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

}

}

}

for(int i = 0 ; i < 3; i++){

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

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

}

printf("\n");

}

}

Output:

14 36 45

35 84 105

56 132 165
