C++ Inputs and ASCII

[Kuberr]

I am currently taking an Intro to C++ course at my local community college.

I have been coding a program, in which I have the following:

cout<<"Please enter in a three-digit number: ";
cin<<Number;

Later on, I have a section that says:

cout<<Number;

Most values work, except values such as 008 don't. The output states that the value of Number is 0. I asked my instructor, and he said that he chose that test data on purpose. He says it has something to do with ASCII. It seems like the C++ is reading the input in with some different method. So how can I fix this?

Can you post your whole program please? And I hope that "cin <<" isn't on purpose.

Yah. That was kind of by accident. It's a bit too late now, but I'd like to know anyways.

// Dennis Ai
// CSC133-GW
// Lab03.cpp
// This program will determine if the digits of a 3-digit number are odd or even.

int main()

int Number, HDCalc, TDCalc, UDCalc, TDQuotient, HDQuotient;
int OddCounter, EvenCounter, ZeroCounter;

OddCounter = 0;
EvenCounter = 0;
ZeroCounter = 0;

cout<<"______________________________________________________________________"<<endl;

else if ((OddCounter>=1) && (EvenCounter>=1))
cout<<"The number contains both odd and even digits.";
cout<<OddCounter<<EvenCounter<<ZeroCounter;
//End main
return 0;
}

i cannot reproduce your problem...

the whole enter 3 digits 00x and get it to equal zero... i always get the value of the number i enter.

maybe you can explain to us how to get the error?

 

[Kuberr]

It's just 008 and 009?

 

[Cx]

well i've tried 008 and 009 and other numbers with two zeros preceding it, still can't get the error.

i tried with the code you've supplied and just a simple cin >> var; cout << var; program, always comes out the correct value.
