Matrix product

Question

İs there someone to recover my matrix product code ?

for(int i=0; i<satir; i++){  

        for(int j=0; j<sutun2; j++){

            for(int k=0; k<sutun1; k++){

                toplam += dizi1[i][k] * dizi2[k][j];

            }

            diziCarp[i][j] = toplam; 

            toplam = 0;  

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

        }

        printf("\n");

    }
    printf("\n");

    return 0;

Answer 1

#include <stdio.h>
#include <time.h>
#include <stdlib.h>

int rng() {
return 1 + rand() % 5;
}

void filler(size_t, size_t, int [*][*]);

int main()
{
srand(time(NULL));
int dizi1[4][4],
dizi2[4][5],
diziCarp[4][5];
size_t satir = 4,
sutun2 = 5,
sutun1 = 4;
int toplam = 0;

printf("Mat A:\n");
filler(4, 4, dizi1);

printf("\nMat B:\n");
filler(4, 5, dizi2);

printf("\nA . B:\n");
for(int i = 0; i < satir; i++){
for(int j = 0; j < sutun2; j++){
for(int k = 0; k < sutun1; k++){
toplam += dizi1[i][k] * dizi2[k][j];
}
diziCarp[i][j] = toplam;
toplam = 0;
printf("%d ", diziCarp[i][j]);
}
printf("\n");
}
printf("\n");
}

void filler(size_t m, size_t n, int arr[m][n]) {

for (int i = 0; i < m; ++i) {
for (int j = 0; j < n; ++j) {
arr[i][j] = rng();
printf("%d ", arr[i][j]);
}
printf("\n");
}
}

Sample Output:

Mat A:
4 3 2 3
4 5 3 3
3 1 1 1
1 1 5 5

Mat B:
5 3 1 5 4
1 5 3 5 3
3 4 5 2 5
5 2 3 2 5

A . B:
44 41 32 45 50
49 55 43 57 61
24 20 14 24 25
46 38 44 30 57
