HOW TO write algorithm and pseudocode

Question

TO find the avrge,max min and sum of three number given by the user

Answer 1

Algorithm:

1. Start
2. Declare variables num1, num2, num3, sum, avg, max, min
3. Read values of num1, num2 and num3 from user
4. Initialize sum as num1 + num2 + num3
5. Calculate avg as sum/3
6. Set max as num1
7. If num2 > max, set max as num2
8. If num3 > max, set max as num3
9. Set min as num1
10. If num2 < min, set min as num2
11. If num3 < min, set min as num3
12. Print sum, avg, max and min
13. Stop

Pseudocode:

DECLARE num1, num2, num3, sum, avg, max, min
READ num1, num2, num3
SET sum = num1 + num2 + num3
SET avg = sum/3
SET max = num1
IF num2 > max THEN SET max = num2
IF num3 > max THEN SET max = num3
SET min = num1
IF num2 < min THEN SET min = num2
IF num3 < min THEN SET min = num3
PRINT "Sum=",sum
PRINT "Average=",avg
PRINT "Maximum=",max
PRINT "Minimum=",min
