includes (STL Samples)
說明如何使用包括 Visual C++ 標準樣板程式庫 (STL) 函式。
template<class InputIterator1, class InputIterator2>
inline bool includes(
InputIterator1 First1,
InputIterator1 Last1,
InputIterator2 First2,
InputIterator2 Last2
)
備註
注意事項 |
---|
在原型中的類別/參數名稱不相符的標頭檔中的版本。某些已修改以提高可讀性。 |
包括演算法的另一個值序列中值的一系列的搜尋。 包括會傳回 ,則為 true 如果範圍中的每個項目 [First2...Last2) is in the sequence [First1..Last1). 這個版本包含兩個序列使用排序會假設運算子 <。

// compile with: /EHsc
// disable warning C4786: symbol greater than 255 characters,
// okay to ignore
#pragma warning(disable: 4786)

//Define an iterator for template class vector of strings

// Define a template class deque of strings

// Initialize vector Vector1
CartoonVector[0] = "Aladdin" ;
CartoonVector[1] = "Jasmine" ;

CartoonVector[3] = "Minnie" ;
CartoonVector[4] = "Goofy" ;

// element of CartoonVector
//Initialize list CartoonDeque

CartoonDeque.push_back("Goofy") ;
start2 = CartoonDeque.begin() ; // location of first
// element of CartoonDeque
end2 = CartoonDeque.end() ; // one past the location last
// element of CartoonDeque
//sort CartoonVector and CartoonDeque alphabetically
//includes requires the sequences
//to be sorted.
sort(start1, end1) ;
sort(start2, end2) ;
// print contents of CartoonVector and CartoonDeque
cout << "CartoonVector { " ;
for(it1 = start1; it1 != end1; it1++)
cout << *it1 << ", " ;
cout << " }\n" << endl ;
cout << "CartoonDeque { " ;
for(it2 = start2; it2 != end2; it2++)
cout << *it2 << ", " ;
cout << " }\n" << endl ;
//Is CartoonDeque a subset of CartoonVector?
if(includes(start1, end1, start2, end2) )
cout << "CartoonVector includes CartoonDeque"
<< endl ;
else
cout << "CartoonVector does not include CartoonDeque"
<< endl ;
}
Output
CartoonVector { Aladdin, Goofy, Jasmine, Mickey, Minnie, }
CartoonDeque { Aladdin, Goofy, Jasmine, }
CartoonVector includes CartoonDeque
