Question

CODING HOMEWORK:

I'm not getting the test case for Acme, Watervliet and Brooklyn. Anyone good at coding could help?

// MichiganCities.cpp - This program prints a message for invalid cities in Michigan.
// Input: Interactive
// Output: Error message or nothing

#include
#include
using namespace std;

int main()
{
// Declare variables
string inCity; // name of city to look up in array
const int NUM_CITIES = 10;
// Initialized array of cities
string citiesInMichigan[] = {"Acme", "Albion", "Detroit", "Watervliet", "Coloma", "Saginaw", "Richland", "Glenn", "Midland", "Brooklyn"};
bool foundIt = false; // Flag variable
int x; // Loop control variable

// Get user input
cout << "Enter name of city: ";
cin >> inCity;

// Write your loop here
for(x=0;x // Write your test statement here to see if there is
// a match. Set the flag to true if city is found.
if(citiesInMichigan[x] == inCity)
foundIt=true; }
if(!foundIt)
cout<<"Not a city in Michigan."<
// Test to see if city was not found to determine if
// "Not a city in Michigan" message should be printed.


return 0;

} // End of main()

// MichiganCities.cpp - This program prints a message for invalid cities in Michigan.

// Input: Interactive

// Output: Error message or nothing

#include <iostream>

#include <string>

using namespace std;

int main()

{

// Declare variables

string inCity; // name of city to look up in array

const int NUM_CITIES = 10;

// Initialized array of cities

string citiesInMichigan[] = {"Acme", "Albion", "Detroit", "Watervliet", "Coloma", "Saginaw", "Richland", "Glenn", "Midland", "Brooklyn"};

bool foundIt = false; // Flag variable

int x; // Loop control variable

// Get user input

cout << "Enter name of city: ";

cin >> inCity;

// Write your loop here

for (x = 0; x < NUM_CITIES; x++) {

// Write your test statement here to see if there is

// a match. Set the flag to true if city is found.

if (citiesInMichigan[x] == inCity) {

foundIt = true;

break;

}

}

if (!foundIt)

cout << "Not a city in Michigan." << endl;

else

cout << "Valid city in Michigan." << endl;

return 0;

} // End of main()

Step-by-step explanation:

In this version of the code, we added a loop that goes through the citiesInMichigan array and compares each element with the input city using an if statement. If a match is found, the foundIt flag is set to true and the loop is exited using break. Finally, we added an else block to the conditional statement that prints "Valid city in Michigan." if the city is found.
