1)  Write a program to display "Hello World"

 2.)   Add and display three numbers without using a variable.

 3). Write a program, which asks the user to input a number. Then display it. 

4.) Finding the average of three numbers. 

5) Write a program to display the following output using a single cout statement Subject Marks Mathematics 80 

Computer 77

 Physics 70 

6 ) Write a program, which displays the value of “π”, then inputs the radius of a circle from the user and displays its area and circumference. Note: You will have to declare a variable for “π” named as “pi” yourself and initialize it the value 22/7. Area = 𝝅𝒓 𝟐 Circumference = 2πr 

7) Write a program to calculate the area and perimeter of the square.

 8) Write a program to calculate the interest of the bank deposit (formula interest= amount*years*rate/100). 

9) Write a program to input/get a number of float types from the user and then show this number as both floats with decimal points and integer without decimal points. 

10) Write a program, which asks the user to enter two numbers, and then output them after Objectives: • Practice and understanding on basic C++ programs swapping their values using the third variable

OUTPUT-:

Enter the variable "a" = 5

Enter the variable "b" = 6

Before Swapping

Value in the variable "a" = 5

Value in the variable "b" = 6

After Swapping

Value in the variable "a" = 6

Value in the variable "b" = 5

11) Write a program to swap the value of two variables without using a third variable.

Clue: Use arithmetic operators such as division ‘/’ and multiplication * or addition + and subtraction

12) Write a program to Convert Temperature from Fahrenheit (℉) to Celsius (℃) 

(formula C=5/9*(F-32)) 

13) Write a program to calculate the quotient and remainder. Use proper names of variables a. divisor b. dividend c. quotient d. remainder
