copied!<p>I think Henning's answer is the way to go.<br> <code>*gDial</code> and <code>*gIP</code> in your code mean <code>gDial[0]</code> and <code>gIP[0]</code>.<br> So, you insert only the first element of the <code>KeyPair</code> array into <code>mMasterList</code>.</p> <p>Your <code>pressKeyPairs</code>'s declaration <code>template<size_t nNumOfElements> void pressKeyPairs(KeyPair(&keys)[nNumOfElements]);</code> itself is correct. It takes a reference to <code>KeyPair</code> array as an argument.<br> However, since <code>mMasterList</code>'s <code>second_type</code> is <code>KeyPair</code>(not <code>KeyPair</code> array), <code>pressKeyPairs((*it).second)</code> invokes type mismatch error.</p> <p>How about the following ideas?</p> <ul> <li>Making a type <code>KeyPairArray</code> which points to <code>KeyPair</code> array</li> <li><code>pressKeyPairs</code> takes a reference to <code>KeyPairArray</code></li> </ul> <p>For example:</p> <pre><code>struct KeyPairArray { size_t nNumOfElements; KeyPair *keys; template< size_t N > KeyPairArray( KeyPair(&k)[ N ] ) : nNumOfElements( N ), keys( k ) {} }; // Example void pressKeyPairs( KeyPairArray const& keys ) { for ( size_t i = 0; i < keys.nNumOfElements; ++ i ) { qDebug()<< keys.keys[ i ].qKey <<','<< keys.keys[ i ].strFormType <<'\n'; } } int main() { map<string,KeyPairArray> mMasterList; map<string,KeyPairArray>::iterator it; mMasterList.insert( make_pair( "Testing Test Menu", KeyPairArray( gDial ) ) ); for ( it=mMasterList.begin() ; it != mMasterList.end(); it++ ) { pressKeyPairs( it->second ); } } </code></pre> <p>Hope this helps.</p>
