Return Statement

return;

A return form that exits the function without returning a value (used in void functions).

return some_expression_or_value;

A return form that exits the function and returns a value produced by an expression or literal.

It returns control (and possibly a value) to the caller—more precisely to the function call expression.

What return Actually Returns To?

Return Terminates the Function

Once a return statement executes, the function exits immediately.

Code After return Is Not Executed

Any statements written after a return statement in the same execution path will never run.

Multiple Return Statements

A function may contain more than one return statement, and whichever is reached first returns control/value immediately.

Conditional Returns

Return statements can be selected by conditions (e.g., returning 1, -1, or 0 depending on input).
