Operators and Expressions

Lesson 4/27 | Study Time: 45 Min

What You Will Learn in This Live Session

1️⃣ Introduction to Operators and Expressions

  • What are operators?
  • Understanding expressions and their evaluation

2️⃣ Types of Operators in C

✔ Arithmetic Operators (+, -, *, /, %): Used for mathematical calculations.
✔ Relational Operators (==, !=, <, >, <=, >=): Used to compare values.
✔ Logical Operators (&&, ||, !): Used for decision-making.
✔ Bitwise Operators (&, |, ^, ~, <<, >>): Perform operations at the bit level.
✔ Assignment Operators (=, +=, -=, *=, /=, %=): Assign and modify values.
✔ Increment and Decrement Operators (++, --): Used for increasing or decreasing values.
✔ Conditional (Ternary) Operator (? :): Short-hand for if-else conditions.
✔ Comma Operator (,): Used to separate expressions.
✔ Sizeof Operator (sizeof()): Determines the memory size of a variable.

3️⃣ Operator Precedence and Associativity

  • Order of execution of operators
  • Rules for evaluating complex expressions

4️⃣ Creating and Evaluating Expressions

  • Writing valid expressions in C
  • Understanding implicit and explicit type conversion
