Need help passing a 2dArray of a Structure by reference!
Apr 20, 2019 at 8:08pm UTC
I'm having trouble passing a 2D array of a structure and editing it in a function. I just typed up a quick little example code to maybe give anybody an idea of what I am trying to do. Every time I fix one error another one occurs. Any help would be highly appreciated.

#include <string.h>
#include <stdio.h>
struct map
{
int sand;
int treasure;
};
//Function setup.
void editMap(struct map* treasure_map[3][3]);
int main()
{
struct map treasure_map[3][3];
editMap(&treasure_map);
return 0;
}
void editMap(struct map* treasure_map[3][3]){
treasure_map[0][0].sand = 15;
printf("%d sand" treasure_map[0][0].sand);
}

It would help you in the long run, if you would describe the trouble and error in more detail.

#include <string.h>

struct Map
{
int sand;

};
void editMap(struct Map treasure_map[][3], int rows );
int main()
{
struct Map treasure_map[3][3];
editMap( treasure_map, 3 );
printf( "%d sand\n" , treasure_map[0][1].sand );
return 0;
}
void editMap( struct Map treasure_map[][3], int rows )
{
if ( 0 < rows )
treasure_map[0][1].sand = 15;
}
