Operators in C programming

You are in a gray zone, the resulting code is the compiler choice and thus it is unpredictable.
The only advice is: never write code with more than 1 increment on same variable in single line of code.
This code:

#include<stdio.h>
main()
{
	int i=2;
	printf("\n%d %d",++i,++i);
	getch();
}

can translate to:

#include<stdio.h>
main()
{
	int i=2;
	int t1=++i;
	int t2=++i;
	printf("\n%d %d",t1,t2);
	getch();
}

or to:
can translate to:

#include<stdio.h>
main()
{
	int i=2;
	int t1=++i;
	int t2=++i;
	printf("\n%d %d",t2,t1);
	getch();
}

It is only compiler choice.
