Question Compiling and executing (C++)


I was going through a list of commands and i saw a command "source"
if i understand correctly it executes commands from files, so i had to try it..

i created a file with a basic loop with c programming, it is very basic:

int a=0, b=5;
while(b>0)
{
a++;
b--;
printf("%d",a);
}

but it wont run... i tried to add the "#include"s and "void main ()" but it didn't change anything...

so i want to know if:
1) source command is running C programming language?
2) is it possible to just create a file with vim and "source" run it or do i have to use some special compiler?

Thank you.

did you have a look at man source?

the way source it typically used is to "reread" scripts, like if you changed something in your /etc/profile and wanted it to take effect right away you would do:

source /etc/profile

to reread the profile and apply the changes. It will not do what you're trying to do above. the only way to run C code is compiling ( since c code starts before main, something has to put the initialization code in the executable and thats where the compiler comes in).
