Multiplication, Division and Modulo

Multiplication Operator

The multiplication operator * yields the product of its operands. For instance, if you're trying to determine the amount of water required to fill a pool:

Division Operator

The division operator / divides the left operand by the right one.

Suppose you want to calculate a car's speed:

Using double variables ensures our result can be a decimal value, providing a more accurate answer. If we only worked with integer types, the result would also be an integer:

It's important to note that merely changing the format specifier won't fix an incorrect integer division:

However, there's a way to get a correct division without introducing another variable:

Note

For a division to yield a decimal result, at least one of the operands should be of a decimal type like double.

Modulo Operator

The % operator returns the remainder of a division. For instance:

Note

If you're trying to display the % character in a string (e.g., in a printf statement), you'd use %% to represent a single %. This tells the compiler you want to print the % character and not use it as a format specifier.
