Question

I need to insert an object to existing vector of objects. I know that i need to use iterator to do it but i dont know how it exactly works.

I have alphabetically sor

Answer 1

I have alphabetically sorted vector and i need to insert new object by its name in exact index that i got after some search.

If the vector is sorted alphabetically, then the proper way of inserting an item in the correct position while maintaining the sort order is using the upper_bound function:

people.insert(upper_bound(people.begin(), people.end(), temp), temp);

The function searches the sorted range, and returns the position of the first element that is greater than temp.
