So, it's easy to say:
if (ivec.size() != ilist.size())
return false;
else
return std::equal(ivec.begin(), ivec.end(), ilist.begin());
I have wrapped everything into 2 functions and I used main(), only to call
them. how about this ?
bool comp_elem( std::vector<int> const& ivec, std::list<int> const& ilist )
{
if( ivec.size() != ilist.size() )
{
return false;
}
else
{
return std::equal( ivec.begin(), ivec.end(), ilist.begin() );
}
}
void print_result( bool result )
{
if( result )
{
std::cout << "VECTOR & LIST are EQUAL" << std::endl;
}
else
{
std::cout << "VECTOR & LIST are NOT equal" << std::endl;
}
}
int main()
{
std::cout << "Enter some integers for VECTOR: ";
std::vector<int> ivec;
std::copy( std::istream_iterator<int>( std::cin ),
std::istream_iterator<int>(),
std::back_inserter( ivec ) );
std::cin.clear();
std::cout << "Enter some integers for LIST: ";
std::list<int> ilist;
std::copy( std::istream_iterator<int>( std::cin ),
std::istream_iterator<int>(),
std::back_inserter( ilist ) );
std::cout << "\nNow we will compare VECTOR & LIST for equality :: ";
bool comp_result = comp_elem( ivec, ilist );
print_result( comp_result );
return 0;
}
