Question

Take the code you wrote in part 1 and create a new function named interactiveStringCounter(). The function gives you three options: 'A' to add a string, 'C' to get a count of a specific string requested and 'X' to exit the program and return a dictionary of counts. I fan incorrect command is given a message should indicate this and ask for another command. If the name is not found when requesting a count ('C') then 0 should be displayed. See the interaction below for guidance. >>> interactiveStringCounter() Please enter a command 'A' for Add, 'C' for count, 'X' to exit:A Please enter a value: cat Please enter a command 'A' for Add, 'C' for count, 'X' to exit: cat Command not recognized please Please enter a command 'A' for Add, 'C' for count, 'X' to exit: cat Command not recognized please Please enter a command 'A' for Add, 'C' for count, 'X' to exit: cat Command not recognized please Please enter a command 'A' for Add, 'C' for count, 'X' to exit:A Please enter a value: cat Please enter a command 'A' for Add, 'C' for count, 'X' to exit:s Command not recognized please Please enter a command 'A' for Add, 'C' for count, 'X' to exit:C Please enter the name to get a count: cat z Please enter a command 'a' for Add, 'C' for count, 'X' to exit:A Please enter a value; mouse Please enter a command 'A' for Add, 'C' for count, 'X' to exit:X ('mouse' i 1, 'cat'; 2) >>>

Explanation / Answer

#include <iostream>

#include <string>

#include <map>

using namespace std;

//Store the string entered in a map that maps strings to the count of string. Call this map 'dictionary'

map<string, int> dictionary;

void interaactiveStringCounter(){

char c;

//Make the user enter a command

cout<<"Please enter a command"<<endl<<"'A' for Add, 'C' for count, 'X' to exit:"<<endl;

cin>>c;

//Check if the command is A, C, X or none of these and act accordingly

//If 'A', then add a new string to the dictionary, or increase the count of the existing string

if(c == 'A')

{

cout<<"Please enter a value"<<endl;

string val;

cin>>val;

//If the string isn't in the map, add it or else increase its count

if(!dictionary[val])

//Adding new string

dictionary[val] = 1;

//Else, increasing count of previous string

else dictionary[val]++;

}

// Display the count

if(c== "C"){

cout<<"Please enter the name to get a count"<<endl;

string val;

cin>>val;

//Display the count of the string entered

cout<<dictionary[val]<<endl;

}

//Iterate and exit in case user enter 'X'

if(c=='X'){

//Iterate through the dictionary to display values

//exit from the program

return;

}

//Else the option entered is invalid

else {

cout<<"Command not recognized please try again."<<endl;

}

//Recursive function

interactiveStringCounter();

}
