23.1.4.Declare a char int 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(pair<char, int>('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
