An array of strings can never collect string from keyboard directly,
it can only be initialized at the time of declaration. But still we can
store strings from the keyboard in the array of characters indirectly, by
storing the string in the simple string variable and then allocate memory
to the pointer of appropriate size and then copy the string from that simple
string variable to the array of pointer.
