Compile C++ file under linux

Question

I am tring to compile and my C++ program on Linux using gcc command.

I used gcc -lm MyOwn.c Main.c -o Out

Myown.c is another file I should link to the main.

The Out file is successfully created.

The problem is Out does not run.

When I tried to use gcc or cc to create exe file it gives me a lot of errors

Can someone help me?

Answer 1

Try

chmod +x Out
./Out

Answer 2

The question is tagged C++. You say you're new c++. But the example you gave involve c code only.

gcc is used to compile c programs.
Use g++ instead.

C++ code files should have the suffix .cpp or .c++, but never .c.

Fix those, try again, and edit the question to add the command line error if it still doesn't work.

Answer 3

Your problem may be that you're compiling as C code. Your files end with a ".c", and you are invoking gcc. You should end the file name with ".cpp" or ".cc" or ".c++" or something else the compiler will recognize as C++.

You can also compile as C++ explicitly by typing g++ instead of gcc.
