PRACTICALS
For Class X (marks 20)
1. Writing a program to demonstrate simple arithmetic operations (e.g. calculation of
the area of a triangle, volume of a cylinder and speed of an object, conversion of
temperature from °C to °F and vice-versa).
2. Writing a program to demonstrate the use of formatted input/output statements,
(calculation of class grades for different students, selection of the largest number
out of given 10 numbers without using a list).
3. Writing a program that uses iteration statements (write a program that reads 5
values from user and find the mean value and compare the mean value against an
actual value of 9.8 meters/sec2
).
4. Writing a program that reads 10 values into an array and after doing some
arithmetic operations, prints the desired results.
5. Repeating Experiment No.3 using a sub-routine, named average and call this subroutine
in the main program.
6. Drawing a line, a circle and a rectangle using system defined built-in functions for
graphics.
