C++ Tutorial/STL Algorithms Helper/make pair
Use make_pair to insert pair value to a map
#include <iostream>
#include <map>
using namespace std;
int main()
{
map<char, int> m;
// put pairs into map
for(int i=0; i<26; i++) {
m.insert(make_pair((char)("A"+i), 65+i));
}
char ch = "G";
map<char, int>::iterator p;
// find value given key
p = m.find(ch);
if(p != m.end())
cout << "Its ASCII value is " << p->second;
else
cout << "Key not in map.\n";
return 0;
}Its ASCII value is 71
