#include <iomanip>

#include <string>
using namespace std;

class CTwo; 
//enum clr{green,yellow,red};

class COne
	{
	public:
		COne(string name1):n(name1)
		{
		
		}
		friend void compares(COne,CTwo);//same friend
	private:
		string n;
	};



class CTwo
	{
	public:
		CTwo(string name2):m(name2)
		{
		
		}
		friend void compares(COne,CTwo);//same friend
	private:
		string m;
	};

void compares(COne a,CTwo b)
{
	if((a.n).compare!=(b.m))
		cout<<"Not Matching"<<endl;
	else
		cout<<"Matching"<<endl;

}

int main()
{
	COne j("red");
	CTwo k("red");
	compares(j,k);
	system("PAUSE");
	return 0;
}


These are the errors

Error 1 - too many characters in constant//what does this mean
Error 2 - 'Circle::Circle(std::string)' : cannot convert parameter 1 from 'int' to 'std::string'	//What does this mean
Error 3 - 'strcmp' : cannot convert parameter 1 from 'Circle' to 'const char *'	//what does this mean


Hope I Will Get Help ... Thank You

Strings should be surrounded with double quotes. Single quotes are for single characters, hence why you are getting the error about "two many characters". The second error is coming from the first, because it is trying to convert the char to an int, and then to a std::string and failing.

The third is because you are using strcmp() to compare your random objects, and you can't do that.
