What is the Yield Keyword?
The yield keyword is a keyword in programming languages such as C#, Java, and Python that is used to pause the execution of a function and return a value to the caller. It is used to create iterators, which are objects that can be used to iterate over a collection of values. The yield keyword is used to create an iterator that can be used to iterate over a collection of values.
How Does the Yield Keyword Work?
The yield keyword works by pausing the execution of a function and returning a value to the caller. When the yield keyword is used, the function will pause and return the value that was passed to the yield keyword. The function will then resume execution from the point where it was paused. This allows the function to iterate over a collection of values without having to write a loop.
Examples of the Yield Keyword
The following is an example of the yield keyword in C#:
public static IEnumerable<int> GetNumbers() {
yield return 1;
yield return 2;
yield return 3;}
The following is an example of the yield keyword in Python:
def get_numbers():
yield 1
yield 2
yield 3
