c++ - Project loaded error after debugging -

edit: took guys' advice , program compiles. can't run because these errors.

'baseconverter.exe': loaded 'c:\users\ownert\documents\visual studio 2010 \projects\baseconverter\debug\baseconverter.exe', symbols loaded. 'baseconverter.exe': loaded 'c:\windows\system32\ntdll.dll', cannot find or open pdb file 'baseconverter.exe': loaded 'c:\windows\system32\kernel32.dll', cannot find or open pdb file 'baseconverter.exe': loaded 'c:\windows\system32\kernelbase.dll', cannot find or open pdb file 'baseconverter.exe': loaded 'c:\windows\system32\msvcp100d.dll', symbols loaded. 'baseconverter.exe': loaded 'c:\windows\system32\msvcr100d.dll', symbols loaded. program '[5320] baseconverter.exe: native' has exited code 0 (0x0). 

here's new updated code. fixed std::cout , have eliminated namespaces, think overloaded coding.

converter.h

#ifndef converter_h #define converter_h using std::cout; using std::cin; using std::endl; //this contains function types needed //reading input //converting base base10 //convert base10 base extern int non10num; extern int bin; extern int bout; extern int b10num; extern int conv; extern int option; extern int sum; extern int num;  #endif    

convertion.cpp

#include <iostream> #include <cmath> #include <string> #include <cctype> #include "converter.h"  using std::cout; using std::cin; using std::endl;  int non10num = 0; int bin      = 0; int bout     = 0; int b10num   = 0; int conv     = 0; int option   = 0; int sum      = 0; int num      = 0; int main () {  //reinstates int variables  int pow = 1;  while (option) { sum += b10num * pow; num /= 10; pow *= non10num; } }

define each 1 in one of cpp files:

int bin = 0;

and declare in others:

extern int bin;

as stands, you're violating 1 definition rule.

also, right now, you're declaring variables of same names in main() going hide global variables in function, not want.
