    findstring(character expression,string,occurance)!=-1

    wat does the condition specifies here.

    That's a tautology (aka always true).

    -1 is never returned by the findstring function, so this expression always yields true.

    Actually, I think you might be thinking of the word truism.

    Tautology is where you say the same thing twice when once is enough - eg, any sentence containing "and also" or "opening gambit."

    You are referring to the rhetoric tautology, I'm referring to the logic tautology.

    a tautology is a formula which is true in every possible interpretation
