Hello there

I made a sample C++ Win32 console application and then added a class CFileParser.

Now i add a function inside the CFileParser called OpeningInstructions() which is declared as public.

Now i include FileParser.h in the main file of the app having MAIN() function and then trying to call the function.............. and it gives an error as shown below.

Fro some reason it's not able to detect the function inside the clas CFileParser.

Any idea how to resolve this?

Thanks in advance

Solution 1

"Added a class CFileParser" suggests that you've written it's code by yourself and added it to your program in the form of source code. Then it is possible that you only declared CFileParser::OpeningInstructions but not defined it. Add the definition with '{}' function body block in some *.cpp file, or, alternatively, inline the function body in your *.h file.
