Write an ARM program that takes a string as input and outputs the number of vowels in the string.

Here is pseudocode for the solution:

Input: string

Output: print out of integer number of vowels in string

Pseudocode:

$1.$ Print greeting and ask for string

$$ use printf, format string is argument to printf, place in x$0$

$2.$ Set a saved register $(\backslash$times $19-$x$27)$ to zero to be used as a counter

$3.$ Scanf to read input

$$ format string is first argument, place in x$0$

$$ address in memory where string will be put is second argument

$4.$ Load the input char from memory into a register $-$ Idrb

$5.$ Check if the char is a null or newline chararacter, if it is$,$ go to step $8$

$6.$ Otherwise check if the char is a vowel $($i$.$e$.$ compare the char with the asci values of A$,$E$.$I.O$,$U$,$a$,$e$,$j$,$o$,$u$)$

$$ If it is a value, increment the counter register

$7.$ Go to step $4$

$8.$ Use printf to print the counter's value
