hi , I have an code, in that code i want know when i will get a duplicate value since values are generated at runtime. could you know the duplicate value by overloading < and == operators. #include #include class A { unsigned long la; unsigned long lb; unsigned long lc; public: A() { la=lb=lc=0; } A(unsigned long ln,unsigned long lm,unsigned long lo) { la=ln; lb=lm; lc=lo; } A(const A& objref) { la=objref.la ; lb=objref.lb; lc=objref.lc; } A& operator =(const A& objref) { if(this!=&objref) { la=objref.la; lb=objref.lb; lc=objref.lc; } return *this; } bool operator==(const A& objref) const { bool b=(((la==objref.la)&&(lb==objref.lb)&&(lc==objref.lc))?1:0); return b; } /* bool operator<(const A& objref) const { if((((la==objref.la)&&(lb==objref.lb)&&(lc==objref.lc))?1:0)) { cout<<"Attempting insert a duplicate value -"<<"("< using namespace std; typedef std::map Aptrmap; int main(int argc, char* argv[]) { A objOne(0,1,2); A objTwo(0,1,2); A objThree(0,1,1); A objFour(3,4,0),objFive(4,4,5); float *pfa,*pfb,*pfc,*pfd,*pfe; pfa= new float(1.10); pfb= new float(2.20); pfc= ne
