C++ add int to int array -

how can add int int array. not want set array size, not want use external loop.

int myarray[] = {}; ... if (condition)  {     myarray.push(value); } 

as leon suggests you're looking vector , push_back method.

you use follows:

vector<int> myarray; // size 0  if(condition) {     myarray.push_back(value); // resized 1; } 

edit:

you can use ostream_iterator print vector. example:

copy(cbegin(myarray), cend(myarray), ostream_iterator<int>(cout, " "))
