gcc 4.4.4 c89
I am just wondering is there any standard that should be followed when creating types.
for example:
typedef struct date
{
} date_t;
I have also seen people put a capital like this:
typedef struct date
{
} Date;
Or for variables
typedef unsigned int Age;
or this
typedef unsigned int age_t;
Is there any standard that should be followed. Personally I prefer post fixing with a _t.
Many thanks for any suggestions,
Follow what the rest of the people do for your project so everything stays consistent. Otherwise they're both acceptable technically.
In general most languages allow the use of SentenceCase for non-standardized classes or types. I find this is the best practise, and in languages that allow it, additionally use namespaces or modules to prevent clashes. In languages that don't (such as C), a prefix where necessary never goes astray. To use a multi-language example for something I'm currently working on:
C: typedef uint32_t CpfsMode;
C++: namespace Cpfs { typedef uint32_t Mode; }
Python: cpfs.Mode = int
