Problem Statement 1

Code it Up!

Write a program such that when the user. 

Use 1. Print Name.

Use 2. Print Address.

Use 3. Add two numbers.

Use 4. Program which takes three values from user and calculate average.

Use 5. Program which takes 5 subject marks from user. Calculate average of it. According to average display appropriate grade.

You can take help from below!
