typo in chapter vector

[Azgolar]

Chapter about vectors:

⭐️ Mainly a vector represent 3 things,

• A pointer to the data
  

• No of elements currently have(length)
  

• Capacity (Amount of space allocated for any future elements).
  

I think it´s supposed to be "number of elements currently have(length)". Sorry if it is correct. I am not a native English speaker, but it confused me.

awesome work, keep it up!
