The number of vowel characters. 2. The number of non-vowel characters. 3. The number of lower case letters. 4. The number of upper case letters. 5. The percentage of upper case letters of all letters. 6. The percentage of vowels of all characters. 7. The number of numerical characters. 8. The number of prime numbers. 9. All prime numbers in the input set. Notes Note 1: iftwo characters are entered at the begging of the input, the program will stop as shown in Fig.1. In this case, the array would be empty. Enter A Set of Characters: Unfortunately, the array is empty! The program will stop now Fig 1 Note 2: To convert a number character to its corresponding numerical value, subtract the zero character from the character itself, for example (int)( 9 0') 9.
