Key Concepts

Literals

Fixed values inserted directly into source code (42, "hello", true)

Operators

Symbols that perform operations on operands (+, -, *, ==, &&)

Precedence

Order of operations - higher precedence operators execute first

Operator Mastery Tips
📝 Literal Types

Integers: 42, Doubles: 3.14, Strings: "text", Chars: 'a', Bools: true/false

🔢 Precedence Rule

Remember PEMDAS: (), *, /, +, -, comparisons, logical operations, assignment.

⚡ Type Safety

C++ is type-safe. You can't add strings and numbers without conversion.

🎯 Parentheses

Use parentheses to override precedence: (3 + 4) * 2 vs 3 + 4 * 2
