How to judge whether the variable naming conforms to the Hungarian nomenclature prefix Please everyo

See Lin Rui's Software Engineering

The Hungarian nomenclature was advocated by Microsoft [Maguire 1993], and although it is cumbersome, it becomes natural to use it. No one forces you to adopt a nomenclature, but one thing you should do: you have to name your programs consistently.

Here's the naming convention I used when programming:

1) Macro definitions are represented by uppercase letters and underscores, such as max length;

2) Functions are composed of words that start with capital letters, such as setname, getname;

3) pointer variable with the prefix p, e.g. *pnode;

4) bool variable with the prefix b, such as bflag;

5) int variable with the prefix i, such as iwidth;

6) float variable with the prefix f, such as fwidth;

7) double variable with the prefix d, such as dwidth;

8) String variables with the prefix str, such as strname;

9) Enumerate variables with the prefix e, such as edrawmode;

10) The member variable of the class is prefixed with m, such as m strname, m iwidth;

For variables of int, float, and double, if the meaning of the variable name is obvious, do not prefix it to avoid annoyance. For example, the int-type variables i,j,k used for loops ; float-type 3D coordinates (x, y, z), etc.

I think variable names can be written in any letter, except for some keywords and function names that are specified in C; Uppercase letters can be used as constants, and are generally used in macro definitions; The capitalization of the first letter of the class name is prescriptive, presumably for the sake of distinguishing; The above is just my understanding, I hope it can help you

A naming method, commonly used in databases, with"_"Separated.

For example: sys user info

It's a style:

int icount;

char cval;

float fscore;

Add the type name to the variable name to make it easy to understand at a glance.

The Hungarian nomenclature is a naming convention when programming. The basic principle is: variable name = attribute + type + object description, in which the name of each object needs to have a clear meaning, and the full name of the object can be taken or part of the name.

It should be based on the original limb branch rules that are easy to remember and easy to understand. It is very important to ensure the coherence of the name.
