Question

18. Use the array strList of strings along with a map<string, int> object mLength to write code

segments that perform designated tasks:

string strList[ ] = { "store", "map", "array", "set"
"multimap", "string" };

int strListSize = sizeof(strList)/ sizeof(string);
map<string, int> mLength;

int i;

a) Write a loop that enters each string from the array into the map as the key-value pair (string, string length).

b)Declare an iterator that locates elements in the map mLength. Use the iterator to output all strings that have a lenght of 5.

Explanation / Answer

#include <bits/stdc++.h>
using namespace std;

int main() {
   string strList[] = { "store", "map", "array", "set","multimap", "string" };
   int strListSize = sizeof(strList)/ sizeof(string);
   map<string,int> mLength;
   int i;
   for (i = 0; i < strListSize; i++){
       mLength[strList[i]] = strList[i].length();
   }
   for (std::map<string,int>::iterator it=mLength.begin(); it!=mLength.end(); ++it){
       if (it->second == 5)
           cout << it->first << endl;
   }
   return 0;
}
