- Write a short C program that declares and initializes (to any value you like) adouble, an int, and a char. Next declare and initialize a pointer to each of thethree variables. Your program should then print the address of, and value storedin, and the memory size (in bytes) of each of the six variables.Use the “%p” formatting specifier to print addresses in hexadecimal. You shouldsee addresses that look something like this: "0xbfe55918". The initial characters"0x" tell you that hexadecimal notation is being used; the remainder of the digitsgive the address itself. Use proper formatting specifiers for char, int and double.Use the sizeof operator to determine the memory size allocated for each variable.Sample output from your program:The address of char ___ is 0x_______The address of int ___ is 0x_______The address of double ___ is 0x_______The address of char* ___ is 0x_______The address of int* ___ is 0x_______The address of double* ___ is 0x_______The value of char ___ is _______The…Write a short C program that declares and initializes (to any value you like) adouble, an int, and a char.
