What happens when you attempt to compile and run the following code?
#include <iostream>
#include <algorithm>
#include <map>
using namespace std;

int main() {
int t[] = { 10, 5, 9, 6, 2, 4, 7, 8, 3, 1 };
map<int, int> m;
for(int i=0; i < 10; i++) {
m[i]=t[i];
}
pair<const int,int> p(5,5);
map<int, int>::iterator it = find(m.begin(), m.end(), p); if (it != m.end())
{
cout<<it?>first<<endl;
}
else
{
cout<<"Not found!\n";
}
return 0;
}
Program outputs:
