size gets to 10 ? And not 5. I pushed back 5 times and initial elements were 0, so why size isn't 5 ?
I used v.size() to find their size
The size of a vector is the number of elements that have been pushed_back to the vector, while the capacity of a vector is the number of elements that the vector's internal storage can hold, the vector's capacity is typically greater than the vector's size, so that the vector can efficiently grow without having to reallocate its internal storage
Yes that's what I want to say bro. I pushed back 5 elements but it showed size = 10
Ohh, it's because the vector's capacity is doubled every time the vector needs to reallocate its memory
I'm not asking about capacity
Maybe, beyond my knowledge at this point
