Can we write a function without return statement?

Can we write a function without return statement?

You may or may not use the return statement, as there is no return value. Even without the return statement, control will return to the caller automatically at the end of the function. A good utilization of a void function would be to print a header/footer to a screen or file.

Does return have to be at the end of function?

That does not always have to be the case, but usually, a return statement is the last line of code in a function since it should be run last. When a return statement is run inside of a function, the function will immediately terminate and return that value, and none of the remaining code lines in the function will run.

How do you end a function?

Unlike the return statement, it will cause a program to stop execution even in a function. And the exit() function can also return a value when executed, like the return statement. So the C family has three ways to end the program: exit(), return, and final closing brace.

Can a function be defined inside a script?

There is a further restriction on functions defined inside a script file: the name of the defined function must not match the name of the script file. In the case of the code you posted, the name of the function does match the name of the script, so even if you added the end statement at the end, you would still have problems.

Why does flowing off the end of a non-void function without..?

There is probably huge code base relying on that “feature”. But at least there is -Werror=return-type flag on many compilers (including gcc and clang). In some limited and rare cases, flowing off the end of a non-void function without returning a value could be useful.

Where do you put the end statement in a script?

In the case of the code you posted, the name of the function does match the name of the script, so even if you added the end statement at the end, you would still have problems. What we have to suspect is that you accidentally put text at the top of your existing function file.
