Difference between cc and cc -c when compiling a C program

Question

I am new to C language and I need to know what is the difference between cc filename.c and cc -c filename.c when compiling a C source code. I know that cc -c command creates an object module, if so how to convert that object module into a executable file.

Answer 1

To create an executable file from object modules, you need to link them using cc or ld or some other linker as follows

 cc a.o b.o c.o -o final.bin

You can also mention the libraries which you want to link here.

It will generate executable if any of these have atmost one entry point (main function).
