What is the default C -std standard version for the current GCC (especially on Ubuntu)?

Question

When I ask to see the current version of cc I get this.

$ cc --version
cc (Ubuntu/Linaro 4.7.2-2ubuntu1) 4.7.2
Copyright (C) 2012 Free Software Foundation, I         


        

Answer 1

The first line will give your GCC version (4.7.2)

(Ubuntu/Linaro 4.7.2-2ubuntu1) 4.7.2

When you compile your code, you can specify which C/C++ revision you want to use, by adding -std=c99 or -std=c99 ...

Note gnu89 is used by default.
