We can use the sizeof operator in the ways described by phoenix.

The only thing we must remember is to put an extra space after sizeof.
For example, if we use:
sizeof i
then it will return the size of i.
But if we use it as:
sizeofi
then only an error message will pop up saying that
sizeofi undeclared.
