stack::size (STL/CLR)
The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.
The latest version of this topic can be found at stack::size (STL/CLR).
Counts the number of elements.
Syntax
size_type size();
Remarks
The member function returns the length of the controlled sequence. You use it to determine the number of elements currently in the controlled sequence. If all you care about is whether the sequence has nonzero size, see stack::empty (STL/CLR)().
Example
// cliext_stack_size.cpp
// compile with: /clr
#include <cliext/stack>
typedef cliext::stack<wchar_t> Mystack;
int main()
{
Mystack 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();
System::Console::WriteLine("size() = {0} starting with 3", c1.size());
// pop an item and reinspect
c1.pop();
System::Console::WriteLine("size() = {0} after popping", c1.size());
// add two elements and reinspect
c1.push(L'a');
c1.push(L'b');
System::Console::WriteLine("size() = {0} after adding 2", c1.size());
return (0);
}
