For this quiz, you must write an implementation of the function reverse in ARM assembly language: void reverse(char *strn); The function reverses the order of the characters in a string. If you pass it the string "abc", it will change the string to "cba". The Run option will run the program in main.c. You can use that for your own testing purposes as you develop your solution. Hints and Suggestions This task is loading bytes, not words, so you will increment by one, not four, and use Idrb and strb instead of Idr and str. This task is much easier if you just keep a pointer to each end of the string. Then increment one and and decrement the other. You can easily tell when you are doing when the they cross each other. Expand for main.C examples. # How do I determine the length of the string? + I get Error: ARM register expected -- 'str .reg r4' I get Error 124 Submit For this quiz, you must write an implementation of the function reverse in ARM assembly language: void reverse(char *strn); The function reverses the order of the characters in a string.
