Q6: Correct the underline:
To set line as a comment not be executed when starting the program, type Dim at the start of the line in the code window.
……………………………………………………………………………..REM…………
To save the student age uses the variable String.
………………………………………Byte or Single……………………………………..
To save data containing decimals and keep them without approximation we use the Long data type.
………………………………………………………………………………………Single
