Accesses the first element.
reference front();
Remarks
The member function returns a reference to the first element of the controlled sequence, which must be non-empty. You use it to access the first element, when you know it exists.
Example
// cliext_queue_front.cpp
// compile with: /clr
#include <cliext/queue>
typedef cliext::queue<wchar_t> Myqueue;
int main()
{
Myqueue c1;
c1.push(L'a');
c1.push(L'b');
c1.push(L'c');
// display initial contents " a b c"
for each (wchar_t elem in c1.get_container())
System::Console::Write(" {0}", elem);
System::Console::WriteLine();
// inspect first item
System::Console::WriteLine("front() = {0}", c1.front());
// alter first item and reinspect
c1.front() = L'x';
for each (wchar_t elem in c1.get_container())
System::Console::Write(" {0}", elem);
System::Console::WriteLine();
return (0);
}
a b c front() = a x b c
