I am writing some code in C (not C99) and I think I have a need for several global arrays. I am taking in data from several text files I don't yet know the size of, and I need to store these values and have them available in several different methods. I already have written code for reading the text files into an array, but if an array isn't the best choice I am sure I could rewrite it.
If you had encountered this situation, what would you do? I don't necessarily need code examples, just ideas.
Use dynamic allocation:
int* pData;
char* pData2;
int main() {
...
pData = malloc(count * sizeof *pData); // uninitialized
pData2 = calloc(count, sizeof *pData2); // zero-initialized
/* work on your arrays */
free(pData);
free(pData2);
...
}
