CalculatorProgram C# Cognizant Handson Solution

Bymadwithcode

Create a class called Calculator which contains methods for arithmetic operations such as Addition, Subtraction ,Multiplication and Division. Division method should return the Quotient and Remainder(hint:use out parameter).

Follow the method signatures as given below:

public int Addition(int a, int b)

public int Subtraction(int a, int b)

public int Multiplication(int a, int b)

public double Division(int a, int b, out double remainder).  //The method should  return the Quotient and Remainder  should be  passed through the out parameter.

The methods should return the appropriate result.

Create a class Program with Main Method . Prompt for 2 operands and operator from the user, Call the appropriate method for operation and display the results.

Note:

Don’t create any new namespace.

Create classes with pubic access specifier

Sample Input

Enter the operator

+

Enter the operands

12

10

Sample Output

Result of 12 + 10 is 22

Sample Input

Enter the operator

/

Enter the operands

11

2

Sample Output

Result of 11 / 2 is 5

Remainder =1

Sample Input

Enter the operator

&

Enter the operands

12

10

Sample Output

Invalid Operator
