Program1(b)

 1. b. Develop a program to read the name and year of birth of a person. Display whether the person is a senior citizen or not.

Objective of the Program

• To read string and numeric input from the keyboard

• To perform age calculation using the current year

• To apply conditional statements for decision making

• To display meaningful output based on logical conditions

Logical Construction (Think Before You Code)

Let us clearly understand the logic before writing the program.

1. The program must read the name of the person.

2. The program must read the year of birth.

3. The current year is required to calculate age.

4. Age is calculated using the formula:  age = current_year – year_of_birth

5. If the calculated age is greater than or equal to 60, the person is a Senior Citizen.

6. Otherwise, the person is not a Senior Citizen.

7. The program displays the result with the person’s name.

👉 The decision is based purely on the age condition.

Flowchart

Algorithm

1. Start

2. Read the name of the person

3. Read the year of birth

4. Set current year

5. Calculate age

6. If age ≥ 60

   • Display “Senior Citizen”

7. Else

   • Display “Not a Senior Citizen”

8. Stop

Python Program

⚠️ Students must complete the missing statements

# Program to check whether a person is a Senior Citizen

name = input("Enter name: ")

year_of_birth = int(input("Enter year of birth: "))

current_year = ____________

age = ____________ - ____________

if age >= ____________:

    print(name, "is a Senior Citizen")

else:

    print(name, "is not a Senior Citizen")

Probable Output

Case 1: Senior Citizen

Enter name: Ramesh

Enter year of birth: 1958

Ramesh is a Senior Citizen

Case 2: Not a Senior Citizen

Enter name: Anitha

Enter year of birth: 1998

Anitha is not a Senior Citizen

Important Concepts Used

• input() function

• Type conversion using int()

• Arithmetic operation

• Conditional statement (if–else)

• Relational operator (>=)

Viva Voce Questions

1. How is age calculated in this program?

2. Why is the year of birth converted to integer?

3. What happens if the current year is changed?

4. Why is >= 60 used instead of > 60?

5. Can this program work for future years?

6. What data type is used to store the name?

7. How can the current year be taken dynamically?

Procedure to Execute the Program

1. Open Python IDLE / VS Code / Google Colab

2. Create a new Python file

3. Type the program

4. Save the file with .py extension

5. Run the program

6. Enter inputs when prompted

Program Explanation

Assignment for Students

• Modify the program to take current year from the system

• Extend the program to classify:

  • Child

  • Adult

  • Senior Citizen

• Validate input to avoid invalid year values
