Assigning Names
2.1 The names of variables, constants, and functions are to begin with a lowercase letter.
2.2 The names of abstract data types (class), structures, typedefs, and enumerated types are to begin with an uppercase letter.
2.3 In names which consist of more than one word, the words are written together and each word that follows the first is begun with an uppercase letter.
2.4 Do not use identifiers which begin with one or two underscores (_' or__').
2.5 Examples
2.5.1 Choice of names
int groupID; // instead of grpID
int nameLength; // instead of namLn
PrinterStatus resetPrinter; // instead of rstprt
2.5.2 Ambiguous names
void termProcess(); // Terminate process or terminal process?
2.5.3 Names having numeric characters can cause errors which are difficult to locate.
int I0 = 13; // Names with digits can be
int IO = I0; // difficult to read. -
Classes
3.1 No member functions are to be defined within the class definition.
3.2 Never specify public or protected member data in a class.
3.3 Examples : No definitions of member functions within the class definition
// Instead of writing like this:
class String
{
public:
int length() const // No !!
{
return len;
}
// ...
private:
int len;
};
// Do it this way:
class String
{
public:
int length() const;
// ...
private:
int len;
};
