An operand is a term used in programming and computer science to refer to the data on which an operator acts. It is an input to an operation, and can be a constant, variable, or complex expression.
In an expression, operands are the values or entities that operators manipulate. For example, in the arithmetic expression 5 + 3, 5 and 3 are operands, and + is the operator.
Example: Here’s an example in JavaScript:
let a = 10; // Operand
let b = 20; // Operand
let result = a + b; // 'a' and 'b' are operands, '+' is the operator
console.log(result); // Output: 30
Operands can also be more complex expressions:
let x = 5;
let y = (x * 2) + 3; // 'x * 2' and '3' are operands, '*' and '+' are operators
console.log(y); // Output: 13
