== Noncompliant Code Example
|
||
|
|
|
||
|
|
----
|
||
|
|
#ifndef HDR // Compliant
|
||
|
|
#define HDR // Compliant
|
||
|
|
#define X(Y) (Y) // Noncompliant
|
||
|
|
#define PI 3.141592 // Noncompliant
|
||
|
|
#endif

== Compliant Solution
|
||
|
|
|
||
|
|
----
|
||
|
|
template<typename T> inline T function(T t) { return t; } // Compliant
|
||
|
|
double const PI = 3.141592; // Compliant
