| deque::clear |
public member function |
Clear content
All the elements in the deque container are dropped: their destructors are called, and then they are removed from the container, leaving it with a size of 0.
Parameters
none
Return value
none
Example
// clearing deques
#include <iostream>
#include <deque>
using namespace std;
int main ()
{
unsigned int i;
deque<int> mydeque;
mydeque.push_back (100);
mydeque.push_back (200);
mydeque.push_back (300);
cout << "mydeque contains:";
for (i=0; i<mydeque.size(); i++) cout << " " << mydeque[i];
mydeque.clear();
mydeque.push_back (1101);
mydeque.push_back (2202);
cout << "\nmydeque contains:";
for (i=0; i<mydeque.size(); i++) cout << " " << mydeque[i];
cout << endl;
return 0;
}
|
Output:
mydeque contains: 100 200 300
mydeque contains: 1101 2202
|
Complexity
Linear on size (destructors).
