How to remove (erase) specific value from unordered multiset in C++

Answer 1

#include <iostream>  
#include <unordered_set>

using std::unordered_multiset;
using std::cout;
using std::endl;


void print(const unordered_multiset<int>& usset)
{
	for (const auto& element : usset) {
		cout << element << " ";
	}
	std::cout << std::endl;
}

int main()
{
	unordered_multiset<int> uml = { 1, 2, 88, 3, 5, 99, 88 };

	auto i = uml.find(88);
	if (i != uml.end()) {
		uml.erase(i);
	}

	print(uml);

	return 0;
}
