What is the difference between delay and sleep in C?

Sleep relinquishes the CPU for specified amount , so that other process can execute. While Delay is just busy waiting for the amount to expire and then continue once expires, it do not execute any other process during this period.

sleep() and usleep() functions | C Programming Tutorial

What is the difference between C yield () and sleep?

Sleep() causes the currently executing thread to sleep (temporarily cease execution). Yield() causes the currently executing thread object to temporarily pause and allow other threads to execute.

What is difference between sleep () and interrupt () method?

How to sleep in C ++ 11?

Since C++11, we can use std::this_thread::sleep_for function to block the execution of the current thread for the specified duration.

What does delay mean in coding?

The coding delay can be defined as the minimum time required to both encode and decode an input data sample.

How accurate is sleep function in C?

It is accurate up to about 20-50 milliseconds. So that it's ok for user experience-dependent things. However it's absolutely inappropriate for real-time things.
