Question

How to create an array of strings when there isn’t a fixed length of items or characters. I’m new to pointers and c in general and I couldn’t understand the other solutions posted on here so my solution is posted below. Hopefully it helps someone else out.

Answer 1

Simply makes an array from the argv items bar the first item.

char **dirs = NULL;
int count = 0;
for(int i=1; i<argc; i++)
{
    int arraySize = (count+1)*sizeof(char*);
    dirs = realloc(dirs,arraySize);
    if(dirs==NULL){
        fprintf(stderr,"Realloc unsuccessful");
        exit(EXIT_FAILURE);
    }
    int stringSize = strlen(argv[i])+1;
    dirs[count] = malloc(stringSize);
    if(dirs[count]==NULL){
        fprintf(stderr,"Malloc unsuccessful");
        exit(EXIT_FAILURE);
    }
    strcpy(dirs[count], argv[i]);
    count++;
}
