Vowel or Consonant with switch
EasyRead one character and print a is a vowel, b is a consonant, or 7 is not a letter, with the character itself in place of the example. Use a switch whose stacked case labels cover the ten vowels in lower and upper case; in the default case use isalpha from <ctype.h> to separate consonants from characters that are not letters. Read the character with scanf(" %c", &ch) so that leading whitespace is skipped. If no character can be read, print invalid input and return 1.
