What is a return statement used for?

A. beginning a function
B. repeating a value
C. copying a function
D. exiting a function

Answer 1

A return statement is used to exit a function and return a value to the calling program or function.

Step-by-step explanation:

A return statement is used for exiting a function and optionally sending a value back to the place where the function was called. When a return statement is executed, the function ceases to execute any further code and control is transferred back to the calling environment.

For instance, in a function that calculates the sum of two numbers, a return statement can be used to provide the sum to the function's caller.

A return statement is used in programming languages like C++, Java, Python to exit a function and return a value to the calling program or function.

When a return statement is encountered in a function, it immediately terminates the function execution, and the control is passed back to the calling program or function.

For example, in Python:

def square(x):
return x * x

result = square(5)
print(result) # Output: 25
