"What control structure in assembly would you need to convert an entire block of integers, given that the number of integers to be converted will only be known at runtime?"

No need of code, just explanation. Thank you.

Question 10: While this program only read and flipped a single integer, usually endianness conversions need to be done over entire blocks of memory. In this question, you are not asked to write assembly code. Consider that you have to write a subroutine that converts the endianness of several integer numbers. For example, your subroutine could receive three parameters: the address of a source memory block that contains the integers to be converted, the address of a target memory block where the converted integers should be placed, and the number of integers to be converted (source and target could be the same address if the endianness conversion is to be done in place). What control structure in assembly would you need to convert an entire block of integers, given that the number of integers to be converted will only be known at runtime
