I am having difficulties understanding this problem, my concept of capacity and size properties of a vector are crystal clear but...
Can anyone solve this problem and explain why you got the answers you did? Below I have added my answers into the questions can anyone explain why I got these wrong or right?
1. capacity of x is 0 and size is 0
2. capacity of y is 7 and size is 0
3. " " z is 4 and size is 2
4. " " w is 6 and size is 0
what is the output of:
5. cout <<w.front() << ' ' << w.back()<<endl;
ans. 0, 39
