Here's a simple C++ program to manage a kirana store:
#include <iostream>
#include <string>
#include <map>
using namespace std;
class KiranaStore {
private:
map<string, int> inventory;
map<string, int> prices;
public:
void addInventory(const string& item, int quantity) {
if (inventory.find(item) != inventory.end()) {
inventory[item] += quantity;
} else {
inventory[item] = quantity;
}
}
void removeInventory(const string& item, int quantity) {
if (inventory.find(item) != inventory.end()) {
if (inventory[item] >= quantity) {
inventory[item] -= quantity;
} else {
cout << "Insufficient quantity in stock." << endl;
}
} else {
cout << "Item not found in inventory." << endl;
}
}
void addPrice(const string& item, int price) {
prices[item] = price;
}
void displayInventory() {
cout << "Current Inventory:" << endl;
for (const auto& pair : inventory) {
cout << pair.first << ": " << pair.second << endl;
}
}
void displayPrices() {
cout << "Current Prices:" << endl;
for (const auto& pair : prices) {
cout << pair.first << ": " << pair.second << endl;
}
}
void calculateBill(const string& item, int quantity) {
if (prices.find(item) != prices.end()) {
int total = prices[item] * quantity;
cout << "Total bill for " << quantity << " " << item << "(s): " << total << endl;
} else {
cout << "Price not found for the item." << endl;
}
}
};
int main() {
KiranaStore store;
while (true) {
cout << "Kirana Store Management System" << endl;
cout << "1. Add inventory" << endl;
cout << "2. Remove inventory" << endl;
cout << "3. Add price" << endl;
cout << "4. Display inventory" << endl;
cout << "5. Display prices" << endl;
cout << "6. Calculate bill" << endl;
cout << "7. Exit" << endl;
int choice;
cin >> choice;
switch (choice) {
case 1: {
string item;
int quantity;
cout << "Enter item name: ";
cin >> item;
cout << "Enter quantity: ";
cin >> quantity;
store.addInventory(item, quantity);
break;
}
case 2: {
string item;
int quantity;
cout << "Enter item name: ";
cin >> item;
cout << "Enter quantity: ";
cin >> quantity;
store.removeInventory(item, quantity);
break;
}
case 3: {
string item;
int price;
cout << "Enter item name: ";
cin >> item;
cout << "Enter price: ";
cin >> price;
store.addPrice(item, price);
break;
}
case 4:
store.displayInventory();
break;
case 5:
store.displayPrices();
break;
case 6: {
string item;
int quantity;
cout << "Enter item name: ";
cin >> item;
cout << "Enter quantity: ";
cin >> quantity;
store.calculateBill(item, quantity);
break;
}
case 7:
return 0;
default:
cout << "Invalid choice. Please choose a valid option." << endl;
}
}
return 0;
}
```
*Example Use Cases:*
1. Run the program and select option 1 (Add inventory).
2. Enter an item name and quantity, e.g., "Rice" and 50.
3. Select option 4 (Display inventory) to view the updated inventory.
4. Select option 3 (Add price) and enter a price for the item, e.g., 50 for "Rice".
5. Select option 6 (Calculate bill) and enter the item name and quantity, e.g., "Rice" and 10.
6. The program will display the total bill for the item.
*How to Compile and Run:*
1. Save the code in a file named `kirana_store.cpp`.
2. Open a terminal or command prompt.
3. Navigate to the directory where you saved the file.
4. Compile the program using `g++ kirana_store.cpp -o kirana_store`.
5. Run the program using `./kirana_store` (on Linux/macOS) or `kirana_store.exe` (on Windows).
