Can you explain what is meant by an operator in programming?

In programming, an operator is a symbol or a combination of symbols that performs a specific operation on one or more operands (values or variables). Operators are used to perform arithmetic calculations, logical comparisons, assignments, and other actions.

For example, in Swift (iOS), the + operator adds two numbers:

let a = 5
let b = 3
let sum = a + b  // sum will be 8

Types of operators:

• Arithmetic: +, -, *, /
• Logical: &&, ||, !
• Comparison: ==, !=, <, >
• Assignment: =, +=, -=

Operators help write expressions that process data and control the program's logic.
