# Arithmetic Operators

**Arithmetic Operators**

Arithmetic operators are used to evaluate mathematical expressions. Arithmetic operators are a form of operator that may either by a Unary Operator or a Binary Operator.

#### Example Programs

**Program [1]**

Write a program that calculates the number of miles that light will travel in 1000 days, which illustrates the use of long integer.

**Program [2]**

Note:

Area of a rectangle=length*breadth

Perimeter of a rectangle=2*(length+breadth)

**Program [5]**

Write a java program to accept the radius and height of cone and calculate the volume of a cone.

**Program [6]**

**Program [8]**

Write a program to input the Principal, Rate and Time for a certain amount of money and print the Simple Interest.

**Program [9]**

Write a program to input the length and breadth of a rectangle and find its area and perimeter.

Note: Area of a rectangle=length*breadth

Perimeter of a rectangle=2*(length+breadth)

**Program [10]**

Write a program to input the radius of a circle and find its area and perimeter.

Note: Area of a circle=22/7* radius2

Circumference of a circle= 2 * 22/7 * radius

**Program [11]**

Write a program to input the length, breadth and height of a cuboid and find its Volume and Total Surface Area.

Note: Volume of a cuboid= length*breadth*height

Total Surface Area=2*(length*breadth+breadth*height+height*length)

**Program [12]**

Write a program to input the radius and height of a cylinder and find its volume and total surface area.

Note: Total Surface Area=22 + 2h

Volume=2h

**Program [13]**

Write a program to input the temperature in Fahrenheit and change it to Celsius.

Note: The relation between Fahrenheit and Celsius is given by the formula:

Where C=Celsius and F=Fahrenheit

**Program [14]**

Write a program to input time in seconds and display the time broken up as hours, minutes and seconds.

For Example:

INPUT: Enter Time in Seconds: 4326

OUTPUT:

Time in hours:1

Time in minutes:12

Time in seconds:6

**Program [15]**

Write a program to input the time in hours, minutes and seconds and print it in seconds.

For Example:

INPUT: Enter time in hours:

1

Enter time in minutes:

12

Enter time in seconds:

6

OUTPUT:

Time in seconds:4326

**Program [16]**

Write a program to input three integers and find their sum, without using the mathematical operator +.

**Program [17]**

Write a program to input the Basic Pay of an employee and find the gross pay of the employee for the following allowances and deductions.

Dearness Allowance = 25% of Basic Pay

House Rent Allowance=15% of Basic Pay

Provident Fund=8.33% of Basic Pay

Net Pay=Basic Pay + Dearness Allowance + House Rent Allowance

Gross Pay= Net Pay – Provident Fund

**Program [18]**

INPUT: Enter an integer: 12

OUTPUT: Sign changed:-12

INPUT: Enter an integer: -14

OUTPUT: Sign changed: 14

**Program [19]**
