How to find my current compiler's standard, like if it is C90, etc

Question

I\'m working on a Linux machine. Is there any system command to find the standard followed by the C compiler I\'m using?

Answer 1

You probably have gcc, in which case you can specify the standard at compile-time, e.g.

$ gcc -Wall -std=c89 foo.c -o foo

or:

$ gcc -Wall -std=c99 foo.c -o foo

Type:

$ man gcc

for full details.
