    Help with checking numbers

    Hi All,

    I am doing an assignment at college to produce a calculator which will only accept a maximum of 6 digits, including the decimal place.

    The only thing i am struggling with is how to check that the user hasnt entered more than 6 digits...


    Does anybody know of a tutorial i could look at?

    or is this a simple thing todo?


    Thanks alot for your help guys

    If you read it as a string, check if strlen(InputString) <= 6.
    For integers, divide the number by 1000000. If the result is greater than or equal to 1, it's more than 6 digits.
