Vector class

P: 1
Hi everyone, i have some issues with the vector class, actually i want to sort my vector or just find something within. I'm tryin to use <algorithm>, made for using list and vector, but it doesn't work very well.... i have many errors while compilating...
Here is the source code :

(struct centre with three integers, x y and mountain)

std::vector<centre> vec;
vec.reserve(500); = w; = u; = z;

and then i use the method sort(vec.begin(), vec.end()); i'd like to sort my vector by mountain....
could you help me please ?? thanks

have a look at this simple example ov sorting avector
Expand|Select|Wrap|Line Numbers
  1.     int idata[]={1,5,7,4,9,78,45,23,56,-2,-8,56};
  2.     vector<int> v;
  3.     for (int i=0;i<sizeof(idata)/sizeof(int); i++) v.push_back(idata[i]);
  4.     for(int i=0;i<v.size();i++) cout << v[i] << " ";
  5.     cout << endl;
  6.     sort(v.begin(), v.end());
  7.     for(int i=0;i<v.size();i++) cout << v[i] << " ";
it pushes the int data onto the vector then sorts it
