Vector Representation of Lines Key concepts: Treat points as vectors to leverage vector addision for point translation. Represent lines using a point plus a direction vector, wich naturally handles vertical lines. Consider two lines intersecting at point I. Line 1 is defined by point p₁ and direction vector v₁, while Line 2 uses point p₂ and ...

Iterators provide a mechanism to access elements within containers like std::vector and characters within std::string. While std::vector and std::string offer common functionalities, only std::vector supports direct index access. Most standard library containers leverage iterators for element traversal. Iterators function similarly to pointers, ...

Matrices and Vectors A matrix is a rectangular array of numbers enclosed by square brackets. For example: [ 1 2 3 ] [ 4 5 6 ] [ 7 8 9 ] [10 11 12] This is a 4×3 matrix (4 rows, 3 columns). The dimension is always given as number of rows × number of columns. Vectors are a special type of matrix with only one column. An n-dimensional vector has ...
