Microchip PIC program problem

[ads-ee]

result = rand();      // generate random value from 0 to 32767
result = result/1000;

But the switch-case on your code considers only 10 options (0 to 9), which means that would be expected a lot of raffles without any update on the lottery display, something in the range of 1/3 ( ~10/32 )

Even though it's not the most uniform solution, The OP could have just done the following:

result = rand()%10; // generate a random value from 0 to 9

That is easier to understand and produces only numbers from 0-9 without having to deal with runs of results outside that range.

Hi. thanks for your help. It works!
