Question

How to use not operator in qbasic? Write a program.

Answer 1

The INPUT command is used to gather input from the user. This section will attempt to teach you how to gather input upon request from the user. For real-time input, see QBasic/Advanced Input.

Here is the syntax of the input command:

INPUT "[text to user]"; [variable] ' Question mark added

or

INPUT "[text to user]", [variable] ' No question mark added

Example:

INPUT "What is your name"; name$

or

INPUT "What is your age", age

When a semicolon (;) is used after the text output to the user, a question mark (?) and 'space' are added to the output. When a comma (,) is used no question mark is added.

If a string is specified (eg 'name$'), anything the user enters before pressing the 'return' key will be accepted. If a numeric variable (eg 'age') is specified, the user must enter a number (if any non-numeric key is entered, the error message "Redo from start" will be output and the INPUT command rerun)
