Array of Strings in c

A string is a 1-D array of characters, so an array of strings is a 2-D array of characters.

Just like we can create a 2-D array of int, float etc; we can also create a 2-D array of character or array of strings.

Syntax for declaring a 2-D array of characters:

char prg[3][12] = {
   {'c', 'o', 'd', 'i', 'n', 'g', '\0'},
   {'l', 'e', 'a', 'r', 'n', 'i', 'n', 'g', '\0'},
   {'p', 'r', 'o', 'g', 'r', 'a', 'm', 'm', 'i', 'n', 'g', '\0'}
};

This above initialization is equivalent to:

char prg[3][12] = {
   "coding",
   "learning",
   "programming"
};

Exercise questions on Array of Strings

  1. Input 10 names and print them.
  2. Input 10 names and find largest word (take ASCII value for comparing).
  3. Input 10 names and find smallest word (take ASCII value for comparing).
  4. Input 10 names and sort them in ascending order.
  5. Input 10 names and sort them in descending order.
