I'm practicing an inventory system, I want to set a function is
Out of stock alert when goods reach the minimum set quantity
I wrote such a piece of code, it compiles without errors, but it doesn't show up


int sum;
     sum == Table3-> RecordCount;
     do
     {
     Label14-> Caption = ("Out of stock !!!");
    } while (sum <= 10);

If sum <= 10, of course, there is no prompt, and while is necessary? ?

mszzzz

How can we change it? Please advise, I am a beginner

1. Feeling that while is not necessary
2.sum == Table3-> RecordCount;
Then sum = 1 or = 0, are you writing it wrong? It should be =

int sum = Table3-> RecordCount;
if (sum <= 10)
         Label14-> Caption = ("Out of stock !!!");
