Use vector for almost everything... | |||
It is an ArrayList. | |||
<syntaxhighlight lang="c++"> | |||
// Basics | |||
vector my_vec; | |||
// Vector with size 5 | |||
vector my_vec(5); | |||
// Vector with size 5 initialized to 1 | |||
vector my_vec(5, 1); | |||
// Length of vector | |||
my_vec.size(); | |||
// Equivalent to size()==0 | |||
my_vec.empty(); | |||
