c++ - error while extending an array: no operator found which takes -

i want extend array 1 when call addbranch function, , add new branch object extended empty area, , trying prevent code memory leak. thought doing right stuck function.

it gives me error "binary '=' : no operator found takes right-hand operand of type 'branch *' (or there no acceptable conversion)". need here assigning last element new branch object won't deleted after extermination of function. new c++, there might big mistakes. not allowed use vectors etc.

  // ------- adds branch system -------- //     void bankingsystem::addbranch(const int id, const string name){         if(isbranchexisting(id)){             cout << "\n\tbranch " << id << " exists. please try id number.";         }         else if(!isbranchexisting(id)){             branch* temparray = new branch[cntaccounts];             for(int = 0; i<cntaccounts; i++){                 temparray[i] = allbranches[i];             }              delete[] allbranches;              allbranches = new branch[cntaccounts+1];             for(int = 0; i<cntaccounts; i++){                 allbranches[i] = temparray[i];             }             allbranches[cntaccounts] = new branch(id, name);  // error @ line          }     } 

as error message says, you're trying assign pointer object. (probably) want assign object instead:

allbranches[cntaccounts] = branch(id, name); // no "new" 

i suggest use std::vector<branch> rather hand-forged arrays. fix memory leak forgetting delete temparray, or throwing exception if add missing delete[].

also, if use vector, whole dance can replaced with

allbranches.push_back(branch(id, name));
