The document provides an overview of QBasic programming, detailing various QBasic statements and their classifications into executable and non-executable types. It includes several programming examples demonstrating how to perform tasks such as calculating the sum of two numbers, finding the area and volume of shapes, and calculating student marks and percentages. These examples illustrate the use of input and output functions in basic QBasic programs.

3. QBASIC Statements:
• Any command or the instructions in the
QBASIC is called a statement. Statements are
classified into executable and non-executable.
Executable statement specify actions and
non-executable statements specify
characteristics, arrangements and initial
values of data.
• Some of the QBASIC statements are:
• CLS
• REM
• INPUT
• LET
• PRINT
• END
• PRINT USING
• LINE INPUT
• LPRINT AND LPRINT USING
• READ….DATA
• RESTORE
• LOCATE
• SWAP

7. WAP to show the sum of two numbers
CLS
REM To find Sum of two numbers
INPUT "Enter the first number"; a
INPUT "Enter the second number"; b
SUM = a + b
COLOR 5
PRINT TAB(5); "The sum of two number is"; SUM;
END

8. • To find Area of Rectangle
• CLS
• REM To find Area of Rectangle
• INPUT "Enter the length" ; l
• INPUT “Enter the breadth” ; b
• AREA = l * b
• PRINT "The area of rectangle is" ; AREA
• END

9. • To find volume of cuboid
• CLS
• REM To find volume of cuboid
• INPUT "Enter the length" ; l
• INPUT "Enter the breadth": b
• INPUT "Enter the height" ; h
• VOLUME = l * b * h
• PRINT "The volume of cuboid is"; VOLUME
• END

10. • To find volume of cube
• CLS
• REM To find volume of cube
• INPUT "Enter the length" ; l
• VOL = l ^3
• PRINT "The volume of cube is" ; VOL
• END

11. • To find area of circle
• CLS
• REM”To find area of circle
• INPUT "Enter the radius" ; r
• LET PI = 3.14
• AREA = PI * r^2
• PRINT "The area of circle is" ; AREA
• END

12. • o find area of circle if radius is 6 cm
• CLS
• REM To find area of circle if radius is 6 cm
• LET r = 6
• LET PI = 3.14
• AREA = PI * r ^ 2
• PRINT "The area of circle is" ; AREA
• END

13. • To input student’s name, marks of any three subjects. Find total and percentage
• CLS
• REM “To find result”
• INPUT "Enter the name of student" ; n$
• INPUT "Enter the marks of English"; eng
• INPUT "Enter the marks of Nepali" ; nep
• INPUT "Enter the marks of Computer"; com
• TOTAL = eng + nep + com
• PER = eng + nep + com / 300 * 100
• PRINT "Student’s name" ; n$
• PRINT "Total marks of student" ; TOTAL
• PRINT " Percentage of student"; PER
• END
