vector::front (STL/CLR)
The latest version of this topic can be found at vector::front (STL/CLR).
Accesses the first element.
Syntax
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 read or write the first element, when you know it exists.
Example
// cliext_vector_front.cpp
// compile with: /clr
#include <cliext/vector>
int main()
{
cliext::vector<wchar_t> c1;
c1.push_back(L'a');
c1.push_back(L'b');
c1.push_back(L'c');
// display initial contents " a b c"
for each (wchar_t elem in c1)
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)
System::Console::Write(" {0}", elem);
System::Console::WriteLine();
return (0);
}
