Which Statement Is Used To Send Value To The Calling Function?

The return statement is used to send a value to the calling function.

Explanation

• Function Termination and Control: When a return statement is encountered within a function, the function's execution is immediately terminated. Control is then transferred back to the point in the calling function where the function was invoked.
• Value Transmission: The return statement can optionally include an expression or value to be sent back to the calling function. This value is referred to as the return value.
• Purpose: The return statement is crucial for functions to communicate the results of their computations or tasks back to the main program flow, allowing for modular and reusable code. For example, a function that calculates the area of a rectangle would use a return statement to send the calculated area back to the code that called it.

Key points

• Syntax: The basic syntax for a return statement is return expression; or return value;.
• Optional Value: A function doesn't necessarily need to return a value. If no value is specified after the return keyword, the function still terminates and control returns to the caller, but the return value is undefined or None in some languages like Python.
• Multiple Return Statements: A function can have multiple return statements, typically within conditional blocks, allowing different values to be returned based on specific conditions.
