When indexing names with numbers written in digit form that contain st or nd (e. g., 2nd Hand News), a. write out the number. b. ignore the letter endings and consider only the digit. c. consider the filing segment as written. d. spell out the number.

Write a program that prompts the user to input a string. the program then uses the function substr to remove all the vowels from the string. for example, if str = "there", then after removing all the vowels, str = "thr". after removing all the vowels, output the string. your program must contain a function to remove all the vowels and a function to determine whether a character is a vowel.
