$2)$ A colleague decided that the PrintInt subprogram should print a new line after the integer has been printed and has modified the PrintInt to print a new line character as follows.

$($Note: PrintNewLine subprogram is described in Chapter $5$ of your textbook.$)$

# subprogram: PrintInt

# author: Charles W$.$ Kann

# purpose: To print a string to the console

# input: $a$0-$ The address of the string to print.

# $a$1-$ The value of the int to print

# returns: None

# side effects: The String is printed followed by the integer

value.

$$

$.$text

PrintInt:

# Print string. The string address is already in $a$0$

li $v$0,4$

syscall

# Print integer. The integer value is in $a$1,$ and must

# be first moved to $a$0.$

move $a$0,$ $a$1$

li $v$0,1$

syscall

# Print a new line character

jal PrintNewLine

#return

When the program is run, it never ends and acts like it is stuck in an infinite loop. Help this colleague figure out what is wrong with the program.

a$.$ Explain what is happening in the program that makes it an infinite loop.

b$.$ Document a solution which fixes this problem so that PrintInt prints the integer and a newline, and then returns to the point in which was called without creating and infinite loop.
