Hi so I've been working on this program and I need help debugging and fixing it$.$ Its $2$ files, one is C and the other is NASM x$86$ Assembly.

The C File:

#include

#include

extern int addstr$\_$asm$($int a$,$ int b$)$;

extern int is$\_$palindrome$\_$asm$($char $*$s$)$;

extern int fact$\_$asm$($int n$)$;

extern void option$\_4()$;

int addstr$($char $*$a$,$ char $*$b$)\{$

int num$1=$ atoi$($a$)$; $//$ Convert strings to integers

int num$2=$ atoi$($b$)$;

return addstr$\_$asm$($num$1,$ num$2)$;

$\}$

int is$\_$palindrome$($char $*$s$)\{$

return is$\_$palindrome$\_$asm$($s$)$;

$\}$

int fact$($char $*$s$)\{$

int num$1=$ atoi$($s$)$;

return fact$\_$asm$($num$1)$;

$\}$

int is$\_$palindrome$\_$c$($char $*$buf$,$ int len$)\{$

int i$,$ j;

for $($i $=0,$ j $=$ len $-1$; i $$ len $/2$; i$++,$ j$--)\{$

if $($buf$[$i$]!=$ buf$[$j$])\{$

return $0$; $//$ Not a palindrome

$\}$

$\}$

return $1$; $//$ Palindrome

$\}$

int main$()\{$

int choice;

char string$1[100]$;

char string$2[100]$;

do$\{$

printf$("$

Menu:

printf$("1.$ Add two numbers together.

printf$("2.$ Test if a String is a palindrome $($C $->$ ASM$).$

printf$("3.$ Print the factorial of a number.

printf$("$Enter a choice: $")$;

scanf$("\%$d$",$ &choice$)$;

if$($choice $<mtext></mtext><mn>1</mn><mtext></mtext><mi>|</mi><mi>|</mi>$ choice $>5)\{$

printf$("$Invalid selection! Please try again."$)$;

$\}$

else if$($choice $==1)\{$

printf$("$Please enter a Number: $")$;

scanf$("\%$s$",$ string$1)$;

printf$("$Please enter another Number: $")$;

scanf$("\%$s$",$ string$2)$;

int result $=$ addstr$($string$1,$ string$2)$;

printf$("$The result of adding the two strings is: $\%$d

$",$ result$)$;

$\}$

else if $($choice $==2)\{$

printf$("$Please enter a String: $")$;

scanf$("\%99$s$",$ string$1)$; $//$ Prevent buffer overflow

$//$ Debug: Print the input string

$//$printf$("$Debug: Input string is $\text{'}\%$s$\text{'}$

$",$ string$1)$;

$//$ Call the assembly palindrome function

int result $=$ is$\_$palindrome$($string$1)$;

if $($result $==1)\{$

printf$("$The string $\text{'}\%$s$\text{'}$ is a palindrome.

$",$ string$1)$;

$\}$ else if $($result $==0)\{$

printf$("$The string $\text{'}\%$s$\text{'}$ is not a palindrome.

$",$ string$1)$;

$\}$

$\}$

else if$($choice $==3)\{$

printf$("$Please enter a Number: $")$;

scanf$("\%$s$",$ string$1)$;

int fact$\_$result $=$ fact$($string$1)$;

printf$("$The factorial of $\text{'}\%$s$\text{'}$ is: $\%$d

$",$ string$1,$ fact$\_$result$)$;

$\}$

else if$($choice $==4)\{$

option$\_4()$;

$\}$

$\}$while$($choice $!=5)$;

$\}$

Unfortunately The assembly code wont fit on here due to the character limit so it will have to be in an image.

exit$\_$option $4$ only has ret for a command.
