Hi all
I need a counter to to count up something
So I use follow code to do this work
unsigned long pdata counter[4]={0,0,0,0};
in the counting place,
counter[0]++;
when run finsih , I print the result
printf(%ld\n",counter[0]};
Maybe I have run to 1000 times ,so counter[0] value
will be to 1000 , but the printf result maybe very
large, like as 92343421;
why ?? how can I make sure to count up correctly??
Thanks a lot
best regards
