C++ STL Vector

[Tampaboy19N]

I create one vector... how to print the element but when the element's value is 20 erase it, and continue to print the element in the vector?

vector<int> v;
for (int i=1; i<6; i++)
{
v.push_back(i*10);
}

Vectors work about the same way as arrays, but they're resizable at runtime :

for(int i = 0; i < v.size(); i++)
{
   if(v == 20)
   {
      v = null;
   }
   else
   {
      cout << "current position = " << v << endl;
   }
}

vector<int> v;
for( vector<int>::iterator iter = v.begin(); iter != v.end(); )
{
if( *iter == 20 )
{
iter = v.erase(iter);
}
else
{
++iter;
}
}
