Scheme Programming/Vector Operations

Creating VectorsEdit

> (vector 1 2 3 4 5)
#(1 2 3 4 5)
> (define v (vector 1 2 3 4 5))
#<unspecified>

Vector ManipulationEdit

> (vector-ref (vector 1 2 3 4 5) 3)
4
> (vector? (vector 1 2 3 4 5))
#t

Vector-ref takes two arguments, a vector and a valid index of the vector, and returns the element at that index.

Notice how the vector is zero indexed. I.e. the first element of a vector is referenced by number 0.
