You are given a string of essentially random characters, and your task is to replace all non-numeric characters with space characters.
1 Instructions
The following files have been provided for you:
1. timedlab3.asm
You will be editing timedlab3.asm to replace instances of non-numeric characters in a string with space characters. The space character (i.e. ' ') corresponds to decimal value 32 in ASCII. All other ASCII characters in the provided string, outside of the range '0'...'9' should be replaced with ' '.
Remember: Strings are zero-terminated arrays of characters!
An ASCII table has been provided for your reference at the end of this document: The space character is highlighted with red and the numeric digits are highlighted with yellow .
We have defined the following assembly language labels for you:
• STR ADDR: The address of the beginning of the string Consider the following examples:
Before
After
"a3hf5k32ss"
" 3 5 32 "
"A3HF5K32SS"
" 3 5 32 "
"aBcD3fGhIj"
" 3 "
Note: Replace characters in the existing string. Do not copy it!
Hint: You may create your own labels with .fills!
