remove value from vector c++

#include <algorithm>
#include <vector>

// using the erase-remove idiom

std::vector<int> vec {2, 4, 6, 8};
int value = 8 // value to be removed
vec.erase(std::remove(vec.begin(), vec.end(), value), vec.end());// Why not setup a lambda you can use again & again
auto removeByIndex = 
  []<class T>(std::vector<T> &vec, unsigned int index)
{
	// This is the meat & potatoes
  	vec.erase(vec.begin() + index);
};

// Then you can throw whatever vector at it you desire
std::vector<std::string> stringvec = {"Hello", "World"};
// Will remove index 1: "World"
removeByIndex(stringvec, 1);
// Vector of integers, we will use push_back
std::vector<unsigned int> intvec;
intvec.push_back(33);
intvec.push_back(66);
intvec.push_back(99);
// Will remove index 2: 99
removeByIndex(intvec, 2);
