Configure the PICs control register so that the Timer0 module will count low-to-high logic transitions (PGTs) on its external clock pin and display them (the total number of switch presses) on an LCD. Connect a properly wired push-button switch to this clock pin, such that when pressed a PGT will be generated. In effect, the counter will count the number of switch presses. If the switch is simply connected in this way the count will probably be erroneous because of contact bounce or noise. Therefore, you should use a debounce circuit with your switch. The switch should work properly, regardless of how quickly or slowly it is pressed. The LCD must always display the proper count value and must update immediately with every switch press. You may assume that the switch will not be pressed more than 50 times.

***** I only need the int main of the code and the numbers have to be converted using ascii.*****

THIS IS WHAT I HAVE SO FAR....
