At the end of your example before the end of the return 0; put std::cin.get();

This will have the program wait for keyboard input from you before it is terminated.

So for example you have your Example.cpp file like this:

int main()
{

//blah blah
std::cin.get();
return 0;
}

You can't use the datatype when calling the functions, just get rid of the voids *on those lines only* not in the declaration/defintions, and I think that will solve that specific problem.

Hi,
I'm having a problem wrapping my head around a problem. Here is the problem:
Develop a program that will input a binary string and then, using bitwise operations, do a two's complement on the string and display it. Use UNSIGNED data types for the bit strings.

So far, I have a class that takes a c-string in the constructor and converts that to an integer using atoi() then I set a temporary variable to the ~ (complement) of the variable and add 1. But I don't really know if I'm even doing it right.

I call it like this:
BinaryString convert("00000010");

And it "works" like this:

BinaryString::BinaryString(char* in)
{
	binary=0;
	input=in;
	doConverttoInt();
}

void BinaryString::doConverttoInt()
{
	binary =( unsigned int)atoi(input);
	std::cout << "binary is " << binary << std::endl;
	performComplement();

}

void BinaryString::performComplement()
{
	
	//input
	unsigned int temp;
	temp = ~binary;
	temp+=1;
	std::cout << "complement is " << temp << std::endl;

}

This all just produces garbage, as atoi strips the leading 0's, and temp variable gives me some ridiculously high number.
