I have a class:

C++

class taphop
{
	public:
	        taphop();
                ~taphop();   
		taphop(const list&);
		taphop& operator=(const taphop&);
		taphop operator+(const int&);
                taphop operator+(const taphop&);
}

in main, i can't using multiple parameters:

C++

main()
{
     taphop lmc=lmc+2+5+3+2; // Error;
     lmc=lmc+3+5+2; // Error;
     int a=a+1+2+4+5;   // Not error;
     return 0;
}

Can everyone help me?? Plz, tks.

You forgot to terminate your class definition. It should have a semi-colon after the closing brace, thus:

C++

class taphop
{
public:
        taphop();
        ~taphop();   
	taphop(const list&);
	taphop& operator=(const taphop&);
	taphop operator+(const int&);
        taphop operator+(const taphop&);
};

Solution 2

very easy:

taphop lmc(2+5+3+2); // write a clear constructor;

Further Tips:

- better style: class names begin with big letter (I like camle-case: TapHop or CTApHop)
- only on statement per line
- in thise case: better use functions instead of operators => add(int n) leads to better debugging
