Thread: Function definition clarification

Generally when developing an application or a logic we need to write a function. There is always chance that you can write either as void function with no arguments or something with function arguments and return values. Which one should i prefer? It is like i need to do lot analysis and come to some conclusion and then actually decide the function prototype. Am I correct? Please advise. Is there any industry standards?

Which one should i prefer?

There is no right answer to this question. Use the function that is right for the occasion. If the function needs information from the outside world, use a function that takes parameters, otherwise don't use parameters, otherwise use function parameters, or the return a value to pass the values to and from your functions.
