Understanding Operators, Operands, and Expressions

Understanding Operators

Operators are special symbols that perform operations on variables and values, known as operands. For instance, in the arithmetic operation 5 + 3, 5 and 3 are operands, while + is the operator.

Understanding Operands

Operands are the entities on which operators act to perform various tasks. In an expression like 5 * 4, both 5 and 4 serve as operands to the multiplication operator *.

What is an Expression?

An expression combines operands and operators to produce a result. For example, the expression a + b - c involves operands (a, b, c) and operators (+, -) and yields a result upon evaluation.

Addition and Subtraction

int num1 = 9;
int num2 = 5;

// Addition
int addResult = num1 + num2; // Result: 14

// Subtraction
int subResult = num1 - num2; // Result: 4
