pair::pair (STL/CLR)

Constructs a pair object.

    pair();
    pair(pair<Coll>% right);
    pair(pair<Coll>^ right);
    pair(Value1 val1, Value2 val2);

Parameters

• right
  Pair to store.

• val1
  First value to store.

• val2
  Second value to store.

Remarks

The constructor:

pair();

initializes the stored pair with default constructed values.

The constructor:

pair(pair<Value1, Value2>% right);

initializes the stored pair with right.pair::first (STL/CLR) and right.pair::second (STL/CLR).

pair(pair<Value1, Value2>^ right);

initializes the stored pair with right->pair::first (STL/CLR) and right>pair::second (STL/CLR).

The constructor:

pair(Value1 val1, Value2 val2);

initializes the stored pair with with val1 and val2.

Example

// cliext_pair_construct.cpp 
// compile with: /clr 
#include <cliext/utility> 
 
int main() 
    { 
// construct an empty container 
    cliext::pair<wchar_t, int> c1; 
    System::Console::WriteLine("[{0}, {1}]", 
        c1.first == L'\0' ? "\\0" : "??", c1.second); 
 
// construct with a pair of values 
    cliext::pair<wchar_t, int> c2(L'x', 3); 
    System::Console::WriteLine("[{0}, {1}]", c2.first, c2.second); 
 
// construct by copying another pair 
    cliext::pair<wchar_t, int> c3(c2); 
    System::Console::WriteLine("[{0}, {1}]", c3.first, c3.second); 
 
// construct by copying a pair handle 
    cliext::pair<wchar_t, int> c4(%c3); 
    System::Console::WriteLine("[{0}, {1}]", c4.first, c4.second); 
 
    return (0); 
    }
