Question / Answers

Question 1. Explain what an algorithm is with the help of an example.

Answer : An algorithm is a detailed step-by-step process that needs to be followed in order to complete a task or to solve a problem.
Example : add two number
  • Program Start
  • a=5
  • b=10
  • c=0
  • c= a + b
  • print a
  • Program End

Question 2. What is a Bug? 

Answer : A bug is a terminology used to describe any unexpected problem in your program. Just like we learnt in the past topics, we follow a sequence of activities to complete a program. This program is expected to return a specific output. Any deviation in the expected and actual output of the program is known as a bug. 


Question 3. Create a pseudocode to check if age entered by the user is of a senior citizen or not. Consider that person is named as a senior citizen if his age is above 60 years old.

Answer :  int age = 61; 
                if (age>=60) 
                    print(“Person is a senior citizen”); 
                else 
                    print(“Person is not a senior citizen”);
                Endif
