Character overloading is also a function, and a function such as const at the end of a function is called a constant member function. The constant member function can be understood as a "read-only" function, which cannot change the value of a data

Operators Header file: "Boost/operators. HPP" The operators library consists of multiple base classes. Each class generates Operators related to its name concept. You can use them in inheritance mode. If you need more than one function, you need to

Needless to say, this is about Operator overload. About operator, the description in can be used as a overload as follows:+ */% ^ & | ~ ! = + = *=/=%= ^= &= |= > >>= >= && | | + + >*, > [] () new new[] Delete delete[]Start with operator = speak

#include #include #include using namespace Std;Class String {PublicString (); str = ""String (const char*); str = "ABC"String (const string&); str = other_stringstring& operator= (const char *);string& operator= (const string&);String operator+

The operands of predefined operators in C + + can only be basic data types, and in fact, for many user-defined types, similar operations are Required. For example:Class Complex{PublicComplex (double r=0.0,double i=0.0) {real=r;imag=i;}void Display ()
