What is the error in this simple code:

#include <stdio.h>

int main()
{
	char a[100];
	int c;
	int i = 0;
	int x = 0;

	while( ( c = getchar() ) != '\n' ) {
		a[x++] =c;
	}

	a[x] = '\0';

	while( ( a[i] != '\0' ) || ( a[i] != '.' ) ) {
		printf( "\ni = %d", i );
		i++;
	}

	return 0;
}

The second while loop does not stops and hence gives a segmentation fault

Compiler gcc 4.6.1
