vector question

[Pat]

Hi,

I use vector<int> to store a list of numbers. Give any number X (may not be
in the vector), I am looking for an efficient way to delete all X's in the
vector.

Any suggestion?
Thanks. Pat

#include <algorithm>
#include <vector>

vec.erase(std:: remove(vec.begi n(), vec.end(), val), vec.end());

#include <iostream>
#include <vector>
#include <algorithm>

int main()
{


std::vector<int > v;
for (int i=0; i<10;i++)
v.push_back(i);
v.push_back(3);
v.push_back(4);

std::copy(v.beg in(),v.end(),
std::ostream_it erator<int>(std ::cout, " "));
std::cout << '\n';

v.erase(std::re move(v.begin(), v.end(),3),v.en d()); //in vector
v.erase(std::re move(v.begin(), v.end(),45),v.e nd()); //not in vector

std::copy(v.beg in(),v.end(),
std::ostream_it erator<int>(std ::cout, " "));
std::cout << '\n';
}

Regards,
Sumit.
