Data Statistics

Algorithm
Step 1 : Start
Step 2 : Initialize 0 to pc, sum, i
Step 3 : Read a number
Step 4 : If number = 9999 then goto step 10
Step 5 : Increment i by 1
Step 6 : If number􀀃􀂔 0 then goto step 3
Step 7 : Increment pc by 1
Step 8 : Add number to sum
Step 9 : Goto step 3
Step 10 : Compute avg = sum / pc
Step 11 : Print i, pc, avg,
Step 12 : Stop
