Implicit function declaration This usually indicates that the header file that declares this subroutine was not #included. When a subroutine is used without having been declared, many C and FORTRAN compilers generate an implicit declaration as "function returning integer."

Such an ‘implicit declaration’ is really an oversight or error by the programmer, because the C compiler needs to know about the types of the parameters and return value to correctly allocate them on the stack. Unfortunately in C this is not an error but a warning (for legacy reasons, to be able to compile old non-compliant code).

An implicit declaration means to call a function without previously telling the compiler that this is a valid function. You tell the compiler the function is valid by a)coding the function before you call it the first time or b)using a function prototype if the code for the function does not appear before the first call.

Every function must be explicitly declared before it can be called. In C90, if a function is called without an explicit declaration, the compiler is going to complain about the implicit declaration. 2008-07-17 Simple issue, but I think you're not seeing the forest for the trees.

A function declaration is a declaration of a function. In other words a function declaration declares the name of the function and the type of what it returns. You must declare an identifier before you can use it. A function prototype is a declaration of a function that declares the types of the function’s parameters. These days, that’s most, if not all of them.

In your case, you haven't included the library stdlib.h at the start of your code. So the compiler sees the call to function before its prototype. I want to use two functions func1 and func2 from the following C++ header file in a xyz.c file. I included the C++ header file in xyz.c (C file).
