like lets say the private variables in a class are type int

in the default constructor, youd do int ... = 0;

what do you do if youre private variable is a vector

[strange jewel]

it will be created with the default constructor of the vector

as an empty vector

[thick pebble]

yes but how do you declare the empty vector

just vector <int> ...; ?

[strange jewel]

when you don't initialize fields which are classes, like the vector, the default constructor gets used automatically to initialize those fields

[thick pebble]

okay so i dont have to make it equal to anything

[strange jewel]

no

bet thanks
