	printf("Enter substring: ");
	gets(inputSubstring);


	for(j=0;inputSubstring[j]!='\0';j++){
		length++;
	}
	for (i = 0, j = 0; inputString[i] != '\0' && inputSubstring[j] != '\0'; i++)
	{
		if (inputString[i] == inputSubstring[j])
		{
			j++;
		}
		else
		{
			j = 0;
		}
	}
	if (j == length){
		startingPosition=i - j;
		endingPosition=startingPosition+length-1;
		printf("%d %d\n",startingPosition,endingPosition);
		printf("Length is %d\n\n",length);
	}else{
		  printf("Substring not found\n\n");
