'begin' has not been declared when used with a pointer

I have a piece of code as follows:

#include<algorithm>
#include<vector>

std::vector<std::string> vect;
std::vector<std::string> * vectP;

vect.push_back("ele0");
vect.push_back("ele1");

void func(){
    if(std::find(*vectP.begin(),*vecP.end(),"ele0")!=*vectP.end())
    //'begin' and 'end' have not been declared
}

Why are begin and end not declared when they're used with pointers? *vectP should be treated as if it's vect since it's dereferenced, or have I misunderstood something? How should I rectify this?

You got your operator precedence wrong. *vectP.begin() means *(vectP.begin()) (which doesn't work, of course), not (*vectP).begin(), which is what you mean. But you should probably spell that vectP->begin().
