C++ Introduction

## A Little Math

These five mathematical operators (`+`

, `-`

, `*`

, `/`

, and `%`

) serve to carry out various mathematical operations:

main.cpp

The **modulo operator** (`%`

) calculates and returns the remainder resulting from a standard division operation.

The **division operator** (`/`

) returns only the integer part of the result, discarding any remainder. For instance, when dividing 10 by 3, the result is 3, not 3.333... To obtain the desired division result with decimals (e.g., 10 / 3 = 3.333), it is necessary for at least one of the operands to be of a `double`

or `float`

data type.

main.cpp

The **sum operator** is the only mathematical operator that can be applied to string (that called **concatenation**):

main.cpp

There are also **comparison operators** (`>`

, `<`

, `<=`

, `>=`

). They are utilized when you need to numerically **compare** a value to a specific range:
