Im trying to wrap the component in the session Provider so that if the user is not logged in they get kicked out. but i get an error when i run

Question

import type { AppProps } from 'next/app'; import { SessionProvider } from 'next-auth/react';

function MyApp({ Component, pageProps: {session, ...pageProps} }:AppProps) { return ( <Component {...pageProps} /> ) }

export default MyApp

Answer 1

But my professor said that 8086 did this operation in two steps instead of one ...

She is wrong:

According to the 8086 data sheet (page 2-52), adding two 16-bit numbers takes exactly the same time as adding two 8-bit numbers: 3 clock cycles.

There are CPUs (like the 8085) which perform a 16-bit addition in two steps; but the 8086 does not do so.

She said that the carry generated by lower sum won't be carried over if we used ADD instruction directly.

This would mean that the ADD BX, CX operation results in 1200h when adding 12FFh and 0001h.

This is TOTAL NONSENSE:

Even the Z80 CPU (which has only a 4-bit ALU) will calculate a result of 1300h in this addition; the 8086 (or 8088) with its 16-bit ALU will calculate the correct result anyway!

Maybe she is confused with the 8085:

The 8085 would not set all flags (e.g. the zero flag) after a 16-bit addition; however, even the 8085 would calculate the correct result and set the carry flag correctly.

Is her solution the only accepted way of adding two 16-bit numbers?

Every compiler would use the ADD BX, CX instruction in this case.

Your professor wants to see if you have understood how to use the ADC instruction.

For this reason, using ADD BX, CX is not what she wants to see.

However, if she didn't tell you that you should use 8-bit additions only, your solution is correct!
