Creating a Simple Menu Card using Switch Statement in C

This program is written in C and it is used to create a simple menu card for a cafe or restaurant.

The program starts with the inclusion of the header file "stdio.h" which contains the functions used in the program, like printf() and scanf().

The program then displays a menu card with 4 options: Coffee, Tea, Cold Coffee, and Milk Shake along with their prices. The user is prompted to enter their choice of product using the scanf() function.

The program then uses a switch statement to check the value of the user's choice and execute the corresponding code block. The switch statement compares the value of the variable 'ch' with the cases 1, 2, 3, and 4. If the value of 'ch' matches any of the cases, the corresponding code block is executed.

In each case, the program prints out the selected product and prompts the user to enter the quantity of the product. Then, it calculates the total amount of the order by multiplying the quantity with the price of the product. Finally, it prints the total amount.

In case if the user has entered any other value other than 1,2,3 and 4, the default case is executed which prints "Invalid Product Selection"

Finally, the program returns 0 to indicate successful execution.
