Programming basics
Begin Your Coding Journey
Understanding the fundamentals of programming
Programming is the art of telling a computer what to do using a step-by-step set of instructions. Think of it like writing an operating manual—computers don't think for themselves, so you have to be precise in your instructions.
Why Programming Languages?
Computers don't understand human language. We use programming languages like Apex, Java, and Python to bridge this communication gap.
How Programming Works
Write Code
Create instructions in your chosen programming language
Translate Code
A compiler convert human-readable code into machine language
Execute Code
Computer processes instructions step by step
What is syntax
Every programming language follows specific rules called syntax. Just like grammar ensures sentences make sense in English, syntax ensures programs run without errors.
Using Comments
Comments make your code more readable and maintainable.
// Single line comment
/* Multi-line comment
explaining complex logic */
Debug Logs
Debug logs help you track program execution and identify issues. They provide visibility into what's happening inside your application at runtime. In apex, you can use system.debug() statement to print the values.
System.debug("The log statement");
