Document Summary
Data structures: an arrangement for storing data in a computer"s memory (primary or. Data structures: b-tree *see example on slide 7* Used for indexes; each node divides left (lower values) and right (higher values) Store and extract data on hard disk faster. Example: add 2 numbers and output the sum. Use special shapes to represent different steps in a process. Functions: the logic of the flowchart is translated into a function. ~ parameters carry data values to the function. Data: data is stored in primary memory as the function runs. Program debugging: the process of making sure a program is free of errors. Fortran: the oldest high-level programming language; designed for scientific and mathematical applications. applications. Pascal: designed to teach structured programming; useful for math and science. Visual basic: an object-oriented, fourth-generation version of basic. Java: object-oriented programming language commonly used for web applications. Object: a template for all instances that have identical behaviors and properties.
