Explanation:

Unsigned Hexadecimal for integer

printf("%x\n", a);

The given code is a C program that prints the hexadecimal representation of the integer value 15 using the printf() function with the format specifier %x.

Here's how it works:

  • The #include <stdio.h> line includes the standard input/output library in the program.
  • The main() function is the entry point of the program.
  • The variable a is declared as an integer and assigned the value 15.
  • The printf() function is used to display the hexadecimal representation of a using the %x format specifier.
    • %x is a format specifier used to display an integer in hexadecimal (base 16) format using lower-case letters.
  • The \n character is used to insert a newline after the output is printed.
  • Finally, the return 0; statement terminates the program and returns 0 to the operating system indicating that the program executed successfully.
