Switch

The document is a C program that uses a switch case statement to allow a user to select an arithmetic operator and then perform a calculation based on the operator chosen. The program asks the user to enter a choice number between 1-4 to select addition, subtraction, multiplication, or division. It then prompts the user to enter two numbers and performs the calculation, printing the result. If an invalid number is entered, it prints an error message.
