C++ program assistance needed

Hello all,

I've got a question regarding a programming assignment that is due by midnight. The objective is to create a program that converts a binary number (up to 32 bits long) to decimal. The problems I have run up against thus far are:

1) Without the error checking for an entry being 1 or 0, I have a problem getting the original binary number to be displayed on the "____ in binary is ____ in decimal." line.

2) With error checking, it keeps automatically passing by the binary number entry line and saying that it is not a valid binary number.

Here is my current code:

Code:

`#include <iostream>`

#include <iomanip>

using namespace std;

int main()

{

char entry[32];

char decision, exit_option;

int place = 0, digit, decimal = 0;

int n = 0, power = 1;

cout << "This program converts positive integer binary numbers"

<< " (up to 32 bits) into a decimal number.\n\n"

<< "Would you like to convert a binary number? (Y or y): ";

cin >> decision;

exit_option = 'Y';

while((exit_option == 'Y')||(exit_option == 'y'))

{

if((decision == 'Y')||(decision == 'y'))

{

cout << "\n\nPlease enter your binary number:\n\n";

cin >> entry[0];

while (entry[place] != '\n')

{

place ++;

cin >> noskipws >> entry[place];

}

if((entry[place] != 1)||(entry[place] != 0))

{

cout << "\n\nThis is not a binary number. Try again? ";

cin >> exit_option;

}

else

{

for(digit = place-1; digit >= 0; digit --)

{

decimal += (entry[digit] - '0')*power;

power *= 2;

}

cout << entry[place] << "in binary is " << decimal << " in decimal.\n\n";

cout << "Continue? (Y or y): ";

cin >> exit_option;

}

}

else

{

cout << "Thanks anyway!";

exit_option = 'n';

}

}

cout << "\n\nThank you for using the Binary Number Convertor!\n\n";

return 0;

}

Thanks for any help/advice given.
