What is the main purpose of the infix format in expressions and where is it used?

The infix format (infix notation) is a way of writing arithmetic and logical expressions where operators are placed between operands. For example, the expression a + b is written in infix form.

The main goal of infix notation is to make expressions more readable and understandable for humans, as it corresponds to the familiar mathematical syntax.

Infix notation is widely used in programming, mathematics, and calculations. However, for computing expressions, computers often use postfix (Reverse Polish) or prefix notation, as they are easier to parse.

An example of an infix expression:

val result = (a + b) * c

Here, the + operator is between a and b, and the * operator is between the result of the addition and c.
