we can not predetermine the value of the capacity? it is upto the compiler or can we calculate it by ourself?
Doubt regarding v.capacity()
It’s nothing like that, if you have an empty vector, you push one element in vector it’s size become 1 & capacity 2;
you push 5 element in vector it’s size become 5 & capacity 8;
That is capacity increases with power of 2 whenever it reaches it’s limit.
