Answer 1

Allocate a 2 dimensional character array dynamically for krajina.

Refer this question:
2 Dimensional Memory Allocation

EDIT: Elaboration:

Alright. You said you can count the number of countries. Say you store that in a variable called count ok?

Now you need to allocate a 2D character array with count number of rows and 31 columns right? You do this as follows.

int i = 0;
int **country = NULL;

if (!(country = calloc(count, sizeof(*country)))) //allocate rows
    return (0);
for (i = 0; i < count; i++)
{
    country[i] = calloc(31, sizeof(*(country[i]))); //allocate columns
}

Now you have the country variable which you can use normally like how you would use a 2d char array (like youve used in your code)
