Both programs debug well ! :/

If i made a program which prints on the screen " Mike " infinite times without stop . how can i define a certain key if i pressed the program stop printing ? ====== I use ' getch() ' method but the program had to stop and check my entry and this isn't my question here.

How can i define the enter key to stop a working loop in my program ? for advance .. 2-programs here which enter key defined both with different ways ! ==============

#include
#include
#include

int main()
{

int x=1;
r:
    printf("Allah  %d\\n", x);
    x++;
    while ( getch() != '\\r')
    {
        goto r;
    }
    return 0;

}

and the other one ..

#include
#include
#include

int main()
{
int nm = 0, ch = 0, wr = 1,i=0;
char x;

while ((x=getchar()) != '\\n')
{
	if (isdigit(x))
	{
		nm++;
	}
	else if (isalpha(x))
	{
		ch++;
	}
	else if (x == ' ')
	{
		wr++;
	}
	i++;
}
printf(" \\n");

printf("Numbers entered = %d , Characters entered = %d , Words entered = %d", nm, ch, wr);
printf(" \\n");
system("pause");
return 0;

}

The first one enter was defined as '\r' while the second was '\n' ! which is the right way ?!
