Hi well i have a big prob , i wonder if u can help me... to solve it, look i have to do , a templete with a few operations with one array , so i have the , inserrt , the erase, search etc.. so , in the main i use a ponter to make the array , so my prob is that i need to overlaod de operator [ ] but i dont know how i ll call form main i have the function to overload it but... i dont how ,i will send the code ....

Code:template<class T> class arreglo { private: T *A; int length; int top; public: arreglo (int inilength); ~arreglo(); insert (T data); expand (int inc); int &operator[](int index); //HERE IS ThE FUNC }; #include <iostream.h> /*********************************/ template<class T> arreglo<T>::arreglo(int inilength) { if(inilength<2) inilength=2; //cout<<inilength; length=inilength; A=new T[length]; top=-1; } /*********************************/ template<class T> arreglo<T>::~arreglo() { delete [] A; } /***********************************************************/ template<class T> arreglo<T>::insert(T data) { top++; if(top>=length) //cout <<"expandiendo"; expand(length/2); *(A+top)=data; //cout<<endl<<"dato escrito"<<endl; } /**************************************/ template<class T> arreglo<T>::expand(int inc) { T *temp; temp=new T[length+inc]; for(int i=0; i<=length; i++) { *(temp+i)=*(A+i); } delete A ; length=length+inc; A=temp; //cout<<top<<length; } /**************************************/ template<class T> arreglo<T>::printarreglo() { cout<<endl<<"Datos en el arreglo"<<endl; for(int i=0;i<top+1;i++) cout<<*(A+i)<<" "; cout<<endl; } /******************************************************/ template<class T> int &arreglo<T>::operator[](int index) { /*if(index<0 || index>top) { cout<<endl<<"NO se encontro el indice "<<endl; return -1; } else*/ { cout<<endl<<"Ya lo encontre"<<endl; return *(A+index); } } /******************************************************/ HERE THE FUNCTION void main() { arreglo<double> *nuevo; nuevo = new arreglo<double>(1); //nuevo->print(); nuevo->insert(30.2); nuevo->insert(40.4); nuevo->insert(50); nuevo->printarreglo(); delete nuevo} // ADN HERE I DONT KNOW HOW TO MAKE //THE OPERATION OVRLOAD CALL
