[c-prog] problem with vector iterator

[wolexzo2]

Below is a template of a function isNumberInVector.
I get errors about the iterator when I run this program.
errors such as

error: expected `;' before `p'
`p' was not declared in this scope
error: dependent-name `std::vector::iterator' is parsed as a non-type, but 
instantiation yields a type


I don't get error when I simply make the function non-template and use 
vector<int> instead.

So What could be the cause?
Thanks,
Lawal. O


#include <iostream>
#include <string>
#include<cstdlib>
#include<vector>
using namespace std;

template <typename T>
 bool isNumberInVector( vector<T>&v,T numToCheck)
     {
         bool isPresent=false;
         vector<T>::iterator p;
         for(p=v.begin();p!=v.end();p++)
             if((*p)==numToCheck) isPresent=true;

        return isPresent;


     }



int main(){

    vector<int> vect;
    for(int i=0;i<20;i++)
        if(i%2==0)

    vect.push_back(i);

    int number=4;
    if(isNumberInVector(vect,number))cout<<"Yes It is";
    else cout<<"No it isn't";

}
