- Here, we declare three integer variables width,
length, and area.
- Then, we assign width to 10 and length
to 5.
- We calculate the area of the square by multiplying them, and store the result
in a variable called area.
- Note that star (*) sign is a sign for multiplication. For addition and
subtraction, use + and - sign
respectively. Division can use a slash (/).
Remainder or modulo can be done using a percent sign (%).
