Create a program that analyzes the vowels in a character string. Define a null-t

Question

Create a program that analyzes the vowels in a character string. Define a null-terminated string of alphanumerical characters. For example "In phonetics, a vowel is a sound in spoken language, such as an English ah! Or oh!, pronounced with an open vocal tract". The program has to have the following subroutines: - only for ARM200: a printing subroutine that prints the entry and resulting string - a subroutine that takes a character and analyzes whether the character is a vowel If the character is a vowel, converts the vowel in uppercase and increments a count of vowels. A main e in sequence: - only for ARM200: first prints the origin string - calls the subroutine that parses the string -for every character calls the subroutine for vowel analysis - replaces the received character back in the string -only for ARM200: at the end prints the resulting string and the count of the vowels.

Explanation / Answer

Assembly Code is:

.LC0:
.string "Enter the string:"
.LC1:
.string " Number of vowels in string :"
