Question

So i've written the MIPS assembly code below which takes in the weight of 4 players of a game and then decides who the winner is based on who's weight is the largest. The only problem is I need to use a procedure method that should look something like this:

main: ...
... jal cp # procedure call
...
cp: ... jr $ra # return to the caller

Here's the code ive written:

.data

# Create null terminated strings to use
strPromptFirst: .asciiz "Enter the weight of player 0: "
strPromptSecond: .asciiz "Enter the weight of player 1: "
strPromptThird: .asciiz "Enter the weight of player 2: "
strPromptFourth: .asciiz "Enter the weight of player 3: "
strResult0: .asciiz "Player 0 wins with weight = "
strResult1: .asciiz "Player 1 wins with weight = "
strResult2: .asciiz "Player 2 wins with weight = "
strResult3: .asciiz "Player 3 wins with weight = "
