[PIC] Multiplexing 7segment

[alimemory]

I came across with this what s
(1) for (i = 0; i<=50; i++)
(2) unsigned short i, DD0, DD1, DD2, DD3;
unsigned int Count
what means? and explain

1) This is for loop which is use to repeat the process for 50 times.
2) unsigned means all are positive numbers and short is range for numbers. these are the data types.
