jadi gini gan, gw diminta bikin perkalian matrix pake pointer dimana hasilnya kudu pake double pointer, nah programnya:

#include<stdio.h>

#include<malloc.h>



int main(void)

{

 int **result_mat;

 int a,b,c,d,m;

 int *row_mat,*col_mat,q;



 printf("Masukkan angka untuk baris dan kolom: ");

 scanf("%d",&m);



 row_mat=(int *)malloc (m*sizeof(int));

 col_mat=(int *)malloc (m*sizeof(int));

 result_mat=(int **)malloc (m*sizeof(int *));



 printf("Baris anda = ");

 for(b=0;b<m;b++)

 {

 row_mat[b]= (int) (b+1);

 }



 for(b=0;b<m;b++)

 {

 printf("%d\t", row_mat[b]);

 }



 printf("\nKolom:\n");



 for(b=0;b<m;b++)

 {

 col_mat[b]= (int) (b+1);

 }

 for(b=0;b<m;b++)

 {

 printf("%d\n", col_mat[b]);

 }



 printf ("hasil perkalian\n");

 for(a=0;a<m;a++)

 {

 for (b=0; b< m; b++)

 {

 for (c=0; c< m; c++)

 {

 result_mat[a][b] += col_mat[a][c] * row_mat[c][b];

 }

 }

 }



 for(a=0;a<m;a++)

 {

 for (b=0; b< m; b++)

 {

 printf("%d\n", result_mat[a][b]);

 }

 }



 free(row_mat);

 free(col_mat);

 free(result_mat);

return(0);

}

pas di run, dia teriak


nah, gw bingungnya rumus perkalian matrixnya gmn kalo buat yg double pointer.. adakah solusinya sepuh" sekalian?
