By Richa Kathuria

Computer Language

As we need a language to communicate with each
other, similarly we need a language to communicate
with computer.

There are two types of languages for computer:
1. Low Level Languages : in form of 0s and 1s.
2. High Level Languages : they are like English, that
we can understand easily.

Qbasic

Basic is the first high level language.

Very simple to learn and understand.

Qbasic is Quick Basic , its a popular version of
Basic.

For windows 7 we need at least Qbasic 32 bits.

We use “commands” to give instructions to the
computer in a computer language.

Simple commands

PRINT- to display any text to the output screen
Eg PRINT”Hello”
Output : Hello

INPUT- this is used to take any value from the user.
Eg If you want to print user's name on the screen ,
then take input from user.
INPUT name$

END- this is to end the program, program will not
run the commands after that.

The first Glance: Qbasic window

Explanation
Program to Print Hello
Print “Hello”
END

Press F5 to run the program and see the output.

Here Print command will direct the text “Hello” to the
output screen.

END will end the program.

Output will only be Hello , commands are not shown there.

Explaination

Program to print name of user
PRINT "Hello"
PRINT "Enter your name"
INPUT name$
PRINT "Your name is "; name$
END

Here name$ is a variable to store value of name.

Input command is used to take value from the user.

When we print value of a variable , no double quotes are
used.
