Computer Programming Basics

Computer Programming Fundamentals

• A computer program consists of instructions written in a programming language for performing specific tasks.
• Syntax refers to the rules and structure governing how code must be written and formatted within a programming language.

Program Components

• Program statements are individual commands that dictate computer actions.
• A compiler converts high-level language code into machine code that can be executed by a computer.

Error Types in Programming

• Syntax errors occur when code violates syntax rules, blocking the program from running.
• Debugging is the systematic process of finding and resolving errors (bugs) in a program.
• Logic errors lead to incorrect program behavior or outputs without preventing execution.

Variables and Data Management

• Variables are named memory locations that can store data values, which are subject to change during program execution.
• The data type classifies the kind of data a variable can hold, such as integers, strings, or booleans.
• Variable declaration involves defining a variable's name and its corresponding data type prior to its usage in a program.
