Can't figure out pointer/array/string in C

I am new to C and I have no idea how to handle this array:

char *args[MAX_LINE/2 + 1];

What does this line mean exactly? Is it a pointer to an array of chars? The assignment given with this was to fill this array with multiple string tokens, but I don't understand how a char pointer can store a whole string?

char *args[MAX_LINE/2 + 1];

args is an array of pointer to char of size MAX_LINE / 2 + 1. Each element is a char*, i.e., each element may be a string. You'll have to initialize them though (i.e., point them somewhere valid.) For example, to read from stdin:

args[0] = malloc(some_size);
/* read a string from standard input */
fgets(args[0], some_size, stdin);

That is basically an array of pointers. Each of the pointer points to a location that holds a char .

Take a look here for more details on handling it. http://www.tutorialspoint.com/cprogramming/c_array_of_pointers.htm
