When I compile .c file it always creates .exe file with name 'a'

Question

I use GCC compiler to compile and run C program on CMD. When I compile C program using command gcc hello.c it creates an executable file file with name a.exe but when I use IDE it uses the name same as .c file as hello.exe. Is it possible to create .exe file name same as .c file on CMD?

Answer 1

Just tell GCC the output name you want.

gcc hello.c -o hello

Answer 2

You have to specify the name of the executable

gcc -c hello.c // compiling

gcc -o hello hello.o // linking
         ^------------------------- name of the executable

you can do the compiling and the linking in one command

gcc -o hello hello.c
         ^------------------------- name of the executable

Answer 3

You need to understand the syntax of output. Following is the description of the command:

$ gcc [options] [source files] [object files] -o output file

In your case you should execute the commands as following:

$ gcc myfile.c -o myfile
$ ./myfile
