Redirected to atomicity.h when trying to compile

When I try to run and compile the code below, I get redirected instead to the file "atomicity.h" on line 45, which says "static inline _Atomic_word "

My question is, what is going on here, and how do I get the code to run and compile properly?

#include <iostream>

int main()
{
	int anArraySize = 9;
	int anArray[anArraySize] = { 4, 6, 7, 3, 8, 2, 1, 9, 5 };
	
	for(int nIndex = 0; nIndex < anArraySize; loop++);
	std::cout << anArray[nIndex] << " ";
	
	return 0;
}
I realized where it says "loop++" it should say "nIndex++", regardless, same outcome when trying to compile.
You need to post atomicity.h if your issue is within atomicity.h.

We can't diagnose code that hasn't been posted.
Also, it should be
 
const int anArraySize = 9;


instead of
 
int anArraySize = 9;

I never intended to use atomicity.h in the code, as I am just working my way through basic tutorials.

Here is atomicity.h:

If you don't intend on using atomicity.h, I would just remove it from your project so you don't get the error anymore.
Atomicity was never in the code to begin with. This is the code:
I have amended "loop++" to "nIndex++"

	const int anArraySize = 9;
	int anArray[anArraySize] = { 4, 6, 7, 3, 8, 2, 1, 9, 5 };
	
	for(int nIndex = 0; nIndex < anArraySize; nIndex++);
	std::cout << anArray[nIndex] << " ";
	
	return 0;
}


For some reason I get redirected to the atomicity.h file when I try to compile.
