Write, and test using QEMU, a RISC$-$V assembly procedure that takes as its two parameters the starting address of a $($zero$-$terminated$)$ string, and a character c$,$ and returns the number of occurrences of the character c in the string.

Write a main program to test your procedure. Your main program should input a string from the user $($you can assume that the string will be at most $40$ characters, not including the zero byte delimiter$),$ and then prompt for input of a character c$.$ If the character c that the user inputs is the newline character $($ascii code $10),$ your program should terminate. Otherwise, your program should invoke your procedure, output the number of occurrences of the given character c$,$ and then prompt for input of another character c$,$ continuing in this manner until the input character is the newline character. Your code must use the $$standard$$ conventions covered in class for passing parameters and returning results.
