Unit 3: Object-Oriented Programming in C++

3.4.4 Expression in C++

• A combination of operators and operands is called Expression.
• Operands may be variables, constants, or both.

1. Arithmetic Expression:

• A combination of Arithmetic operators and numeric constants/variables is called an arithmetic expression.
• In a C program, the arithmetic expression is used to calculate the value of an arithmetic formula. 

Examples:

         a + b;
         34 – 22;

2. Relational Expression:

• An expression that contains a relational operator to compare values of the same type is called a relational operator.
• It is used to create conditions in programming.

3. Compound or Logical Expression:

• An expression that combines two or more conditions using a logical operator is called a compound expression.
