вот так например

#include <ostream>
#include <iomanip>
template<int N,typename FwdIter>
void WriteBytes(std::ostream& out,FwdIter& from,const FwdIter end)
{
using namespace std;

out<<' '<<setw(2)<<static_cast<unsigned int>(static_cast<unsigned char>(*from++));
if (from==end)
out<<setfill(' ')<<setw((8-i)*3)<<"";
}
void dump(std::ostream& out,const char* first,const char* last)
{
using namespace std;
ios_base::fmtflags savedFlags = out.flags();
out<<hex<<right<<noshowbase<<setfill('0');
out<<endl;
for(const char *it1=first,*it2=first;it1!=last;)

out<<" |";

out<<" | "<<nouppercase;

out<<endl;
}
out<<"- конец дампа (длина = "<<dec<<last-first<<"+2) -"<<endl<<endl;

}
void dump(std::ostream& out,const char* ptr,size_t siz)
