Are you sure that the first part of your program will count as a decade counter ? When a digit reaches 9, it is changed to 0 before increment ?

Also the programming style is not to be proud of. I would suggest the following:

	i=0;
	counted_pulses[i]++;
	while ((counted_pulses[i]>=10)&&i<4) {
	   counted_pulses[i]=0;
	   i++;
	   counted_pulses[i]++;
	   }

It's shorter and more clear. It's made for 4 digits, 0 is the lowest. (I haven't tried the program).
