Please write a C$++$ code and please explain every line of code and make sure the code as basic as possible since the course is a programming $1$ course

Question $1$: points$]$

Write a $C++$ main program that asks the user to enter the value of an integer number $x.$ The program first checks the value for $x.$ if $x$ is not zero, then the program computes and displays the value of $Z$ as per following expression:

$Z=x+\frac{(x+1)}{(x^5+x^{10}+x^{15}+\text{c}\text{d}\text{o}\text{t}\text{s}+x^{50})}$

If $x$ is $0,$ then the program prints a message "ERROR", and then the program terminates $($exits$).$ The program must use a looping structure. All division must be real, floating$-$point division.
