Question

C++

Write a program that reads in a list of 10 names as input from a user and places them in an array.

The program will prompt for a name and return the number of times that name was

entered in the list. The program should output total number of instances of that name and then prompt for another name until the word done is typed in.

For this lab, use the string data type as opposed to char to store the names (i.e. don’t use c-strings).

Expected Input/ Output:

Enter name #1: Joe

Enter name #2: Sally

Enter name #3: Joe

Enter name #4: Sue

Enter name #5: Sally

Enter name #6: Adam

Enter name #7: Joe

Enter name #8: Adam

Enter name #9: Adam

Enter name #10: Joe

Who do you want to search for (enter done to exit)? Joe

There are 4 instances of the name Joe.

Who do you want to search for (enter done to exit)?Sally

There are 2 instances of the name Sally.

Who do you want to search for (enter done to exit)? Adam

There are 3 instances of the name Adam.

Who do you want to search for (enter done to exit)? Sue

There is one instance of the name Sue.

Who do you want to search for (enter done to exit)? John

John’s name does not exist in this list.

Who do you want to search for(enter done to exit)?done

#include <iostream>
#include <string>

using namespace std;

int main() {
    string names[10], name;
    for (int i = 0; i < 10; ++i) {
        cout << "Enter name #" << i + 1 << ": ";
        getline(cin, names[i]);
    }
    while (true) {
        cout << "Who do you want to search for (enter done to exit)? ";
        getline(cin, name);
        if (name == "done")
            break;
        int count = 0;
        for (int i = 0; i < 10; ++i) {
            if (names[i] == name) {
                count++;
            }
        }
        if (count == 0) {
            cout << name << "'s name does not exist in this list." << endl;
        } else if (count == 1) {
            cout << "There is one instance of the name " << name << "." << endl;
        } else {
            cout << "There are " << count << " instances of the name " << name << "." << endl;
        }
    }
    return 0;
