Again, the compiler is not asking you to jam random things into the middle of your code when it says main doesn't exist. It's asking you to add main(), unrelated to your code, outside it.
Of course, if you want your function to be run, you should tell main() to run it, since main runs everything.
Code:
#include <iostream>
using namespace std;
// Your function
int identity(int input)
{
int output = input;
return output;
}
// The function which the compiler will call when the program is run
int main() {
int output=identify(32);
}
At first I got another error, but I realized you used "identify" instead of "identity", so that's fixed. Anyway, the output is nothing when I run ./bh.exe(the filename of this code). Is this correct?

wibble-test-genrunner
wibble-test-genrunner(1) General Commands Manual wibble-test-genrunner(1)NAME
wibble-test-genrunner - Code generator for wibble testsuites.
SYNOPSIS
wibble-test-genrunner header <file>
wibble-test-genrunner main <files>
DESCRIPTION
The program generates .cpp files that are then compiled and linked into a test program for running tests from .test.h files. Examples of
such .test.h files may be found among wibble headers, eg. /usr/include/wibble/regexp.test.h.
In the first form, the program processes a single header file (usually of the form foo.test.h) and produces a corresponding .cpp file to be
compiled. In the second form, it takes as <files> all the .test.h headers and produces a single main.cpp which contains the main() function
of the test program, which then runs all the tests in all the .test.h files. The generated source code is always written to standard output
and it is left up to the user to redirect it to a meaningful location.
The program currently has no options other than the two forms above. The program is intended to be run as part of build process of programs
or libraries using the wibble testing framework. For convenient use from CMake, there is a test.cmake script under /usr/share/wibble, that
takes care of producing all the .cpp files (both per-header and the main one), compiling them and linking them into a single binary which
executes the testsuite.
