Assume letters A , E , I , O , and U as the vowels. Write a program that prompts the user to enter a string and displays the number of vowels and consonants in the string. Hint1: consonants is a non-vowel letter. Hence, non-letter characters need to be ignored from the counting process. Hint2: Use method gets() to read the input string gets(yourString) Use method toupper() to convert each read letter to its capital equivalent to simplify the letter checking process e.g., toupper(ch) will return A if ch= a Using C programming.
