How to sort functions in C? “previous implicit declaration of a function was here” error

Question

I\'m sure this has been asked before, but I couldn\'t find anything that would help me. I have a program with functions in C that looks like this

function2(         


        

Answer 1

This is how C works. We need to declare the function before use. like when you use any variable, you must have declare first then you would have use it.

Declaration:- function1(); function2(); and then put your own code.
