Programming Language Constructs

From SwinBrain

Programming languages are designed to write algorithms (i.e. instructions) that are performed by a computer. These languages contain the following constructs.

• Data Types Ways in which data is represented in programs.
• Statements represent the individual instructions to the computer.
• Expressions represent calculations or operations that result in a value.
• Identifiers are used to name things in a program such as variables, procedures, functions, etc.
• Keywords are identifiers that represent commands in the language.
• Literals are numeric and textual constants entered directly into the programs source code.
