Final answer:
The set of rules that must be strictly followed when writing a program is known as the programming language's grammar. Like the grammar of a spoken language, programming grammar dictates the proper combination of elements to write executable commands. Programming languages also evolve, integrating new syntax to keep up with technological advancements.
Step-by-step explanation:
Each language in programming has a set of rules that must be strictly followed when writing a program. This set of rules is called grammar, similar to the grammar used in spoken languages. Grammar in programming languages dictates how the elements of the language can be combined to form valid instructions that can be executed by a computer. For example, English grammar determines how verbs are conjugated; similarly, a programming language grammar specifies how functions, variables, and other constructs must be used to create proper syntax. Just like natural languages, where regional differences can result in variations like 'soda' or 'pop,' programming languages can have different standards or implementations, but the core grammar rules must be adhered to for the program to run correctly. As technology evolves, new terms such as 'e-mail' and 'Internet' have been incorporated into our lexicon, reflecting the dynamic nature of language. Programming languages also evolve, adding new syntax and structures to enable programmers to solve problems more efficiently or to address new technological developments.
