I need to erase map elements using an iterator inside a function which takes map iterator as argument, but getting runtime error(free(): double free detected). This is my code:
#include <iostream>
#include <map>
std::map<int32_t, int32_t> mapp;
void erasee(std::map<int32_t, int32_t>::iterator itr) {
itr = mapp.erase(itr);
}
int main()
{
mapp.emplace(1, 1000);
std::map<int32_t, int32_t>::iterator itr = mapp.begin();
while(itr != mapp.end()) {
std::cout << "before" << std::endl;
erasee(itr);
std::cout << "after" << std::endl;
}
return 0;
}
