ENGL7101 Chapter Notes - Chapter 5: Mathematical Notation
Document Summary
Pseudo code is an outline of a program, written as a series of instruction using simple english sentences. Pseudo code uses keywords commonly found in high-level languages and mathematical notation. It des(cid:272)(cid:396)i(cid:271)es a(cid:374) algo(cid:396)ith(cid:373) s steps like program statements, without being bound by the strict rules of vocabulary and syntax of any particular language, together with ordinary english. Variable is memory location where a value can be stored. They can be used to store data that is needed at runtime. In contrast to variable, the content of a constant can"t change at runtime, it has a constant value. Before the program can be executed (or compiled) the value for a constant must be known. Assignment is the process of writing a value into a variable (a named memory location).
