In which program a return statement does not return a value?

Q. In which subprogram a RETURN statement does not return a value and so cannot contain an expression? Procedures are the subprograms which do not return a value directly because they are mainly used for performing actions.

Which function does not return any value?

Correct Option: A. Void functions does not return a value. Functions with no return value are sometimes called procedures.

What does a Python function return if no return is given?

In Python, every function returns something. If there are no return statements, then it returns None. If the return statement contains an expression, it’s evaluated first and then the value is returned. The return statement terminates the function execution.

What happens if you don’t return a value?

If you do not explicitly return a value, the caller will nonetheless use whatever garbage happens to be in that register. The compiler will also use all registers it has available for internal computation within the function.

In which the program written statement does not return a value and so Cannot contain an expression?

In procedures, a RETURN statement does not return a value and so cannot contain an expression. The statement returns control to the caller before the end of the procedure. In functions, a RETURN statement must contain an expression, which is evaluated when the RETURN statement is executed.

Why do we use return in Java?

A return statement is used to exit from a method, with or without a value. For methods that define a return type, the return statement must be immediately followed by a return value. For methods that don’t return a value, the return statement can be used without a return value to exit a method.

Which function does not return any value Mcq?

Explanation: VOID functions should not return anything.

How do you return a no value in Python?

There is no such thing as “returning nothing” in Python. Every function returns some value (unless it raises an exception). If no explicit return statement is used, Python treats it as returning None .

What is empty return in Python?

It means it will return None . You could remove the return and it would still return None because all functions that don’t specify a return value in python will by default return None .

Why do constructors not return values?

So the reason the constructor doesn’t return a value is because it’s not called directly by your code, it’s called by the memory allocation and object initialization code in the runtime. Its return value (if it actually has one when compiled down to machine code) is opaque to the user – therefore, you can’t specify it.

What is SQL and Plsql in Oracle?

PL/SQL is Oracle’s procedural language extension to SQL. PL/SQL allows you to mix SQL statements with procedural constructs. Oracle also allows you to create and store functions, which are similar to procedures, and packages, which are groups of procedures and functions.

What is return value in Java?

Java return keyword is used to complete the execution of a method. The return followed by the appropriate value that is returned to the caller. This value depends on the method return type like int method always return an integer value.

Why do some functions have no meaningful value to return?

They do not produce a meaningful value to return, but they influence the program state in one of many possible ways. E.g., the exit function in C returns no value, but it has the side effect of aborting the application. Another example, a C++ class may have a void method that changes the value of its instance variables.

What does return 0 return 1 Exit(0) do in the above program?

What does return 0, return 1, exit (0) do in the above program? exit (0) will exit total program and control comes out of loop but what happens in case of return 0, return 1, return -1. the program terminates immediately execution with exit status set as the value passed to return or exit

Why do functions have to have a ‘return type’?

But often you write functions that do stuff and don’t need to return anything (think e.g. about a function that just prints something on the screen); for this reason, it was decided that, to specify that you don’t want to return anything at all, you have to use the voidkeyword as “return type”.

What does it mean when a program returns 0 (normal termination)?

On unix, 0 means normal termination and non-zero indicates that so form of error forced your program to terminate without fulfilling its intended purpose. It’s unusual that your example returns 0 (normal termination) when it seems to have run out of memory. Q: Why do we need to return or exit? A: To indicate execution status.
