How does the following codes work and what are the errors why it is not debugging. "
#include
extern int add(int a, int b); // External declaration for assembly function
int main(){
// Prompt user for calculator operation
printf("Choose operation (+,-,*,/): ");
char operation;
scanf("%c", &operation);
// Prompt user for two numbers
printf("Enter first number: ");
int num1;
scanf("%d", &num1);
printf("Enter second number: ");
int num2;
scanf("%d", &num2);
int result;
// Call appropriate assembly routine based on the chosen operation
switch (operation){
case '+':
result = add(num1, num2); // Call assembly routine for addition
break;
// Add cases for other operations
default:
printf("Invalid operation
");
return 1; // Exit with an error code
}
// Print the result to the console
printf("Result: %d
", result);
return 0; // Exit successfully
}
```
Now, the corresponding assembly language file (`calculator_asm.asm`) for the addition operation:
```assembly
section .text
global add ; Make the symbol add globally accessible
add:
; Purpose: Add two numbers
; Input: eax = first number, ebx = second number
; Output: eax = result of addition
add eax, ebx ; Add the two numbers
ret ; Return control to the calling C program
