apvector

AP Computer Science Workshop

AP Classes: apvector

Code Effect

apvector<char> a; constructs a 0 element vector of char

apvector<int> a(10), b (20); constructs a 10 element vector of int, indexed 0 to 9

apvector<double> d(5, 0.0); constructs a 5 element vector of double, initialized to 0.0

b = a; assignment works for apvectors (even of different sized vectors)

b.length(); returns vector's current size (10)

d[0] = 7.5; looks like an array

cout << d[2] << endl; ditto

a.resize(50); expandable arrays??? Indeed.

Code	Effect

`apvector<char> a;`	constructs a 0 element vector of `char`
`apvector<int> a(10), b (20);`	constructs a 10 element vector of `int`, indexed 0 to 9
`apvector<double> d(5, 0.0);`	constructs a 5 element vector of `double`, initialized to 0.0

`b = a;`	assignment works for apvectors (even of different sized vectors)
`b.length();`	returns vector's current size (10)

`d[0] = 7.5;`	looks like an array
`cout << d[2] << endl;`	ditto

`a.resize(50);`	expandable arrays??? Indeed.
