"#include" directives should be followed by either <filename> or "filename" sequences

These are the only forms for the #include directive permitted by the standard. The behavior is undefined when other forms are used.

Noncompliant Code Example

#include filename.h        // Noncompliant

Compliant Solution

#include "filename.h"        // Compliant
#include <filename.h>

#define HEADER "filename.h"
#include HEADER
