Is it good to have multiple return statements?

Multiple return statements seem to work well for “guard code” at the beginning of a method, in which the main body of the method is executed only if certain conditions are satisfied. Here, equals has multiple return statements, since a successful test implies that further comparison is redundant.

Can you have more than one return statement in a function?

A function can have multiple return statements. When any of them is executed, the function terminates. A function can return multiple types of values.

How many return statements can a function have?

The body of a function should have only one return statement.

What is the use of return in programming?

A return statement ends the execution of a function, and returns control to the calling function. Execution resumes in the calling function at the point immediately following the call. A return statement can return a value to the calling function.

Should I avoid multiple return statements?

However, some programmers prefer to avoid multiple return statements, even if the language allows it. That way, the program has a single exit point. If you need to do any cleanup in a function, before returning, you should definitely avoid multiple return statements, to duplicating a lot of code.

Is it necessary to have one return statement in every function?

Explanation: A function may have any number of return statements each returning different values. Explanation: True, A function may have any number of return statements each returning different values and each return statements will not occur successively.

Is it necessary to have one return statement in a function?

Answer: Explanation: True, A function may have any number of return statements each returning different values and each return statements will not occur successively.

Can you have multiple return statements in a function Python?

Python functions are not restricted to having a single return statement. If a given function has more than one return statement, then the first one encountered will determine the end of the function’s execution and also its return value.

What does a return statement do in Python?

A return statement is used to end the execution of the function call and “returns” the result (value of the expression following the return keyword) to the caller. The statements after the return statements are not executed.

What role does the return statement plays?

Textbook solution The value to be returned of the calling function is called as return statement. It plays the role to end the execution of the function. After the value is returned by return statement the control goes back to function called.

Is it bad practice to have multiple return statements Python?

It is sometimes said that a method should have only one return statement (i.e. one exit point) and that to code using more than one return per method is bad practice. It is claimed to be a risk to readability or a source of error. Sometimes this is even given the title of the “single exit point law”.

Can we have multiple return statements in Java method?

Java doesn’t support multi-value returns.

Why do we need multiple return statements in a function?

This is to limit the complexity. Many people such as Martin Fowler argue that it is simpler to write functions with multiple return statements. He presents this argument in the classic refactoring book he wrote. This works well if you follow his other advice and write small functions.

Can a method have more than one return statement?

The question is whether a method may have multiple return statements or always just one. The answer may surprise you: In a pure object-oriented world, a method must have a single return statement and nothing else. Yes, just a return statement and that’s it. No other operators or statements.

How many return statements should you have per function in C++?

Structured programming says you should only ever have one return statement per function. This is to limit the complexity. Many people such as Martin Fowler argue that it is simpler to write functions with multiple return statements. He presents this argument in the classic refactoring book he wrote.

Why do some programming languages have single return statements?

If you’re in a language without destructors or if you don’t use RAII, then a single return reduces the number of places you have to clean up. Some languages require a single exit point (e.g., Pascal and Eiffel).
