Combining two cpp files into one cpp file - c++

Question

I am working on an assignment where I have main.cpp,lego.cpp, and lego.h. My program currently runs fine and gives out the desired output. My issue is that to submit, I must have everything in a single cpp file. Would appreciate if someone could give a simple example. (I want everything in main.cpp)
Merge C++ files into a single source file
i found this link that is similar but I cant grasp the example

Answer 1

if anyone has this problem I just fixed it by doing this
class lego {things in class};
lego::functionA(){}
lego::functionB(){}
int main(){};
make sure that you delete any other cpp files that are in your source folder and remove any header files from main. Was what was causing my issue.

Answer 2

Combining two cpp files into one cpp file
On a POSIX system, you can use the following command:
cat main.cpp lego.cpp > combined.cpp
On windows, use type instead of cat.
This trivial approach works for most programs, and very likely for a simple assignment. But this can have problems with more complicated programs in particular those that rely heavily on pre-processor.

Answer 3

using the command prompt by combining the files. you need to put the files that you need to combine in a single folder and using the command line (windows + r, on windows 10) run commands that access the directory in which the files are.
Enter the command copy/b *.cpp combined.cpp That will save the two cpp files into one file combined.cpp.
Then access the combined file combined.cpp in the same directory.
