Hello guys

i'm having a trouble with my vectors, first time i get such problem, whenever i used VectorName->push_back ( something ); all the members in the vector becomes same as the new element,here's the code:



after this code, both amt->MoveField members have the second value, all elements keeps getting same data as the last element, why is that? did i define vectors in a wrong way or something? im pretty sure i did the same thing with one of my programs and it worked well

You do that twice, what do you think it's adding? It's just adding the same ptr twice, also, that ptr will become invalid once the function or whatever that's in returns. So you want to either dynamically allocate new instances of that struct, fill it and add it or write copies.
