Write a SPIM assembly language program numvowels based on th

Write a SPIM assembly language program num-vowel.s based on the example program Is-vowel.s in the lab notes.
The program will do the following:

Prompt the user to enter a null terminated string.

The program will call the procedure vowelp to check if a character entered in the string is a vowel or not.

Count how many vowels and how many other characters are in the string.

Print out the calculated results with appropriate message.

Hint: A loop is needed.

Solution

Answer:

Assembly Language Code :

.zero 1
.LC0:
.string \"Enter an alphabet : \"
.LC1:
.string \"This is a vowel\"
.LC2:
.string \"This is not a vowel\"
