Question

When breaking a problem down, you often encounter elements that you want to use repeatedly in your code. Sometimes it's appropriate to write a new function; at other times it's appropriate to write a loop. There is no hard-and-fast rule as to which is better, but what do you think? What kinds of circumstances would lead you to writing a function versus using a loop?

Answer 1

FUNCTION:

• A function does not require the number of times that the code script needs to be executed

• When we go for large programming, ie. while creating projects, we can invoke function from one file to another based on the access specifier mentioned for the function.

• There is a stack call created in the memory whenever a function is called.

LOOP :

• Whereas the number of times that the loop has to be executed must be defined

• A loop cannot be called, it can be used only the code block in which it is present.

• There is not overhead of creating a stack since it is not invoked and there is no transfer of control from one module to another
