What do programming languages have in common

Programming languages share several fundamental characteristics, even though they have different syntax and purposes.

• Syntax: All programming languages have a defined set of rules for writing valid statements and instructions. This includes how to declare variables, write commands, and structure code.
• Semantics: Each language has a specific meaning attached to its syntax. This defines what a particular instruction or statement will actually do when executed by a computer.
• Data Types: Most languages support basic data types like integers (whole numbers), floating-point numbers (decimals), strings (text), and booleans (true/false).
• Control Structures: They all provide ways to control the flow of execution, such as conditional statements (if/else) and loops (for/while), allowing programs to make decisions and repeat actions.
• Abstraction: Languages offer mechanisms to hide complex details and work with higher-level concepts, making it easier to write and manage large programs.
