This code demonstrates how type casting works in C, particularly with double and int types. Here's a step-by-step explanation:

1. Variable Initialization:

   double x = 1.6;
   

   A variable x of type double is initialized with the value 1.6.

2. Type Casting:

   double y = (double) (int) x;
   

   • Inner Cast: (int) x converts x (which is a double) to an int. Casting a double to an int discards the fractional part, so 1.6 becomes 1.
   • Outer Cast: (double) converts the result back from an int to a double. This means 1 becomes 1.0. As a result, y is assigned the value 1.0.

3. Printing the Result:

   printf("%g\n", y);
   

   The %g format specifier in printf prints y in the most compact form possible (either normal floating-point notation or exponential notation). Since the value of y is 1.0, it will print:

   1
   

4. Return Value:

   return 0;
   

   Indicates that the program executed successfully.

Summary:

This program takes a double value (1.6), converts it to an int (1), then back to a double (1.0), and prints the result (1). It effectively demonstrates truncation of the fractional part during type casting from double to int.
