What is Return?
Return is a keyword used in programming langauges to immediately stop the execution of a function and return to the caller. It is a commonly used statement that exits the program and resumes execution of the caller, also known as a return statement.
Description of Return
Return is used to immediately terminate a function’s execution and return the control to the caller statement. This means that the program code executed after the invocation of the return statement is not executed. Therefore, this statement is used to end a function call and terminate the function itself. It should be noted that the return statement can also be used to return a value from the function to the caller statement.
Uses of Return
Return can be used to end a function and return the control to the caller statement in many cases:
- When a function has reached the end of its execution and the program needs to return to the caller
- When the program needs to return a value from a function that is too large to be contained in a register
- When the program needs to terminate a function with an error code or a return code
It can also be used in other cases such as exiting a loop, exiting a switch statement, or exiting a program.
Return Syntax
The syntax for a return statement is different in various programming languages but usually has the following structure:
- return value;
- return;
The first statement is used when the function needs to return a value and it will return the value stored in the variable value. The second statement is used when the function does not need to return a value and the program execution will be resumed at the caller statement.
Conclusion
Return is a keyword used in programming languages to exit a function and return the control back to the caller statement. It can be used in many cases, such as exiting a loop, exiting a switch statement, or returning a value from a function. The syntax for a return statement is different in various programming languages but typically includes the keyword “return” followed either by a variable or by nothing.
