Write a program using the C++ STL map container to implement simple management of fruit prices, including operations such as adding, printing, searching, modifying, and deleting. In this program, you create a map called `fruitPrices` to store the prices of different fruits. Then add some initial fruit prices, print the current fruit prices, and then allow the user to search for, modify, or delete a fruit price. Finally, print the updated fruit prices.

Sure, I can help you with that. Here's an example program that uses the C++ STL map container to implement a fruit price management system:

#include <iostream>
#include <string>
#include <map>

using namespace std;

int main() {
    // Create a map to store fruit prices
    map<string, double> fruitPrices;

    // Add some initial fruit prices
    fruitPrices["apple"] = 0.99;
    fruitPrices["banana"] = 0.49;
    fruitPrices["orange"] = 0.79;

    // Print the current fruit prices
    cout << "Current fruit prices:" << endl;
    for (const auto& pair : fruitPrices) {
        cout << "- " << pair.first << ": $" << pair.second << endl;
    }

    // Allow the user to search for, modify, or delete a fruit price
    string fruitName;
    cout << "Enter a fruit name to search for, modify, or delete: ";
    cin >> fruitName;

    // Check if the fruit exists in the map
    auto it = fruitPrices.find(fruitName);
    if (it != fruitPrices.end()) {
        // Fruit exists, ask the user what operation to perform
        char operation;
        cout << "What would you like to do with " << fruitName << "?" << endl;
        cout << "  (S)earch for the price" << endl;
        cout << "  (M)odify the price" << endl;
        cout << "  (D)elete the price" << endl;
        cin >> operation;

        if (operation == 'S' || operation == 's') {
            // Search for the fruit price
            cout << fruitName << " costs $" << it->second << endl;
        } else if (operation == 'M' || operation == 'm') {
            // Modify the fruit price
            double newPrice;
            cout << "Enter the new price for " << fruitName << ": $";
            cin >> newPrice;
            fruitPrices[fruitName] = newPrice;
            cout << "Price updated." << endl;
        } else if (operation == 'D' || operation == 'd') {
            // Delete the fruit price
            fruitPrices.erase(it);
            cout << "Price deleted." << endl;
        } else {
            // Invalid operation
            cout << "Invalid operation." << endl;
        }
    } else {
        // Fruit doesn't exist in the map
        cout << "Sorry, " << fruitName << " is not in the list." << endl;
    }

    // Print the updated fruit prices
    cout << "Updated fruit prices:" << endl;
    for (const auto& pair : fruitPrices) {
        cout << "- " << pair.first << ": $" << pair.second << endl;
    }

    return 0;
}

Here's an example interaction with the program:

Current fruit prices:
- apple: $0.99
- banana: $0.49
- orange: $0.79
Enter a fruit name to search for, modify, or delete: apple
What would you like to do with apple?
  (S)earch for the price
  (M)odify the price
  (D)elete the price
m
Enter the new price for apple: $1.29
Price updated.
Updated fruit prices:
- apple: $1.29
- banana: $0.49
- orange: $0.79

I hope this helps! Let me know if you have any questions.
