Problem Statements
Write a program to take two integers as input from the user. First, print their sum and then print their product.
Take the length and breadth of a rectangle as
doubleinputs from the user, and print the area of the rectangle.Take name, roll number and field of interest from the user and print in the format below :
"Hey, my name is xyz and my roll number is xyz. My field of interest are xyz."
Take the side of a square from the user and print the area and perimeter of it.
Take two different string inputs and print them in the same line.
INPUT:
Core
Java
OUTPUT:
Core Java
