i need help to solve the cpu.c task

#

I just can't get it to calculate the value for SPIN_1SEC and then run the program with it

#

nobody is going to do the assignment for you

#

if you need help, ask a question that can be answered

final pewter
#

i posted the part i already tried

#

maybe someone can have a look at it and help me

wanton dagger
#

what do you need help with?

final pewter
#

with this

wanton dagger
#

are there any errors? does the output not match what you expect?

How to Ask A Programming Question

Anyone can ask a question in our programming channels. Following the guide Writing The Perfect Question is recommended.

What To Post

State your problem clearly and provide all necessary details:

  • the relevant portion of your code, or all of it
  • the expected output
  • the actual output (or the full error) 🏆 Gold Standard: Minimal Reproducible Example
Where To Post

Provide the relevant code in the message, and format it nicely with a code block*. If it's too much for one message, you can upload it:

  • Compiler Explorer for most C/C++ snippets
  • OnlineGDB for interaction, debugging ⛔ Do not post screenshots, let alone photos of your screen!
* Use /code if you don't know how to format code blocks

I can't get the SPIN_1SEC value right

#

The cpu is used for 1 sec and this time is measured in nanoseconds, I don't know how to calculate and save this value.

SPIN_1SEC describes how often your computer can increment the i variable within a second.
After 1 second has passed you inspect the value of i. You then repeat this a few times and take the average.

If you do not know how to precisely stop time - cause I sure as hell don't - then my approach would be to bruteforce the number.
I would bruteforce it via binary search over all integers (if unsigned int isn't sufficient then of all integers up to 1 << 40 or smth like that). If for a tested number of iterations the computer needs less than 1 second then you look at the bigger half and if it takes more than a second than you look at the lower half.
