C/C++ Style Guide

About

This style guide applies to C and C++.

Definitions

• If a pointer is being defined as null, use NULL. If NULL is not defined, define it as (void*)0.

• Example:

```c

    double *foo = NULL;

```

Libraries

• Use namespaces.

  • Exceptions: functions which initialize or destroy structures (no conflict if structure name is unique)

• Do not place "using" outside of a function.

• printf should be preferred over std::cout since it is much, much cleaner to read. For a good discussion, see Google's style guide (http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml?showone=Streams#Streams)

Pointers

• When declaring a pointer or multiple on the same line with other declared variable, put the asterisk next to the variable name without a space between it and the variable name.

  • Example:

```c

    int *x, *y, z, q;

```

• When a pointer is declared by itself, put the asterisk next to variable name.

  • Example:

```c

    int *x;

```
