Program must be in C language and MUST be able to run on visual studio

1. Exploring Variables and Memory 1.1 Write a program that: prompts a user to enter a character, an integer, a real number, and an array of five integers o displays each of them and their memory locations in the following form: char value at memory location: 0xhex_number (print the values in place of bold text) int- value at memory location: 0xhex-number (print the values in place of bold text) doublevalue at memory location: 0xhex_number(print the values in place of bold text) int [index] = value at memory location: 0xhex-number (print the values in place of bold text) (Note: hexadecimal numbers in C are denoted by the prefix, 'Ox', to differentiate them from just an alpha-numeric string. Úse the format specifier, %p to print out a memory address.) 1.2 Modify the program in 1.1 to store the char, int and double in a struct. Print the memory location of the struct and the three member variables.
