vector::resize (STL/CLR)
Changes the number of elements.
void resize(size_type new_size);
void resize(size_type new_size, value_type val);
Parameters
new_size
New size of the controlled sequence.val
Value of the padding element.
Remarks
The member functions both ensure that vector::size (STL/CLR)() henceforth returns new_size. If it must make the controlled sequence longer, the first member function appends elements with value value_type(), while the second member function appends elements with value val. To make the controlled sequence shorter, both member functions effectively erase the last element vector::size (STL/CLR)() - new_size times. You use it to ensure that the controlled sequence has size new_size, by either trimming or padding the current controlled sequence.
Example
// cliext_vector_resize.cpp
// compile with: /clr
#include <cliext/vector>
int main()
{
// construct an empty container and pad with default values
cliext::vector<wchar_t> c1;
System::Console::WriteLine("size() = {0}", c1.size());
c1.resize(4);
for each (wchar_t elem in c1)
System::Console::Write(" {0}", (int)elem);
System::Console::WriteLine();
// resize to empty
c1.resize(0);
System::Console::WriteLine("size() = {0}", c1.size());
// resize and pad
c1.resize(5, L'x');
for each (wchar_t elem in c1)
System::Console::Write(" {0}", elem);
System::Console::WriteLine();
return (0);
}
