Here is a very simple console application that I wrote using C# programming language that will ask the user to give two numbers and then it will also ask the user to give an operand like plus sign, minus sign, slash sign and asterisk sign to process the two given input values. The code uses switch statement in C# and our program also ask the user do you want to continue in order for the user to repeat the process of the running the program.I hope you will find my work useful. Thank you.
