Question

Develop an x86 assembly language program that properly executes an absolute value function:

• int abs(int value)
• If the value passed in is negative, the value has its negative sign removed
• If the value passed in is positive, the value is left alone
• Remember that the return value must be placed in the EAX register
• Make sure that any registers (not EAX) used by this function are placed back to their initial states prior to exiting

Allow an end user to test this function in the following manner:

• Prompt the user to enter an integer value ("Enter a value: ")
• Allow the user to input their value
• Pass the user input value to the abs() function
• Let the function do its work and return the correct value
• Print out the result ("The absolute value is: ")
