Task $3(30$ pts$)$: Converting String to Integer

In this task, you$$ll write an assembly code to convert a string to an integer. For example, say a string is declared

in the $.$data segment:

$1.$data

$2$ numstr: $.$string $"382"$

$3$ number: $.$quad $0$

Then your program will convert the string into an integer $382,$ and store it to number $.$ You don$$t need to

consider negative numbers.

Just a refresher: if the string is $"9082",$ the number can be calculated by $9103+0102+8101+2100.$

Be Careful...

The characters in a string are stored as their ASCII values, not the real digit;

When loading a character, or a byte, into a register, the command is LDRB or LDRSB $,$ and the destination

register is Wt not Xt $.$

Requirements

You must use loops or recursion. If you want to use recursion, you must follow calling conventions and

manage stack frames;

You must not assume the length of the string numstr $,$ so you must not declare and hardcode any variable

representing string length in $.$data and $.$text ;

You must store the converted integer into variable number ;

You must not use any external libraries and functions;

You must use system call to print, not printf$()$ ;

Write your name and pledge at the top of the code.
