C Basics

Multiplication (*)

The * multiplication operator forms the product of the values on both sides of the "*" sign.

For example, let's calculate how many liters of water we need to completely fill the pool:

Division (/)

The division operator / divides the right operand's value by the left operand's value.

For example, let's find out the speed of the car:

The double variables were created to make our answer non-integer and, therefore, more accurate. Otherwise, if we manipulate only integer values, the result will also be an integer:

Maybe it will work if you change the specifier? – No.

The result will be completely incorrect:

But there is also a correct calculation option without an additional variable:

Note

To have a non-integer result, one of the variables must be non-integer.

Modulo (%)

Operator % returns the remainder of the normal division. For example:

Note

We used the % character twice in a row to warn the compiler that we wanted to use the % character as a string, not as a specifier.
