Programming code - Programming code is a set of written computer instructions, guided by rules, using a computer programming language. It might help to think of the computer instructions as a detailed, step-by-step recipe for performing tasks. The instructions tell computers and machines how to perform an action. Programming code may also be referred to as source code or scripts.
Programming languages - Programming languages are similar to human spoken languages in that they both use syntax and semantics. Programming languages are used to write computer programs. Some common programming languages include Python, Java, C, C++, C#, and R.
Syntax - Syntax is a set of rules for how statements are constructed in both human and computer languages. Programming syntax includes rules for the order of elements in programming instructions, as well as the use of special characters and their placements in statements. This concept is similar to the syntax rules for grammar and punctuation in human language.
Semantics - Semantics refers to the intended meaning or effect of statements, or collections of words, in both human and computer languages. Semantic errors are also referred to as logical errors.
Computer program - A computer program is a step-by-step list of instructions that a computer follows to reach an intended goal. It is important to be clear and precise about the actions a computer program is supposed to perform because computers will do exactly what they are instructed to do. Computer programs can be long, complex, and accomplish a variety of tasks. They are often developed by computer programmers and software engineers, but anyone can learn to create them. Computer programs may involve a structured development cycle. They can be written in a wide variety of programming languages, such as Python, Java, C++, R, and more. The completed format of a program is often a single executable file.
