Journal Entry

Write a program that opens a file named journal_entries.txt in append mode and adds new content without overwriting the existing data. The program should prompt the user to enter the current date and then the journal entry.

Hint

• Open the file in append mode (std::ios::app) to ensure new data is added to the end.

Answer

#include <iostream>
#include <fstream>
#include <string>

int main() {
    std::string filename = "journal_entries.txt";

    // Open the file in append mode
    std::ofstream outFile(filename, std::ios::app);
    if (!outFile) {
        std::cerr << "Error: Could not open the file " << filename << "." << std::endl;
        return 1;
    }

    // Get the current date and journal entry from the user
    std::string currentDate, journalEntry;
    std::cout << "Enter the current date (e.g., 2024-08-04): ";
    std::getline(std::cin, currentDate);
    std::cout << "Enter your journal entry: ";
    std::getline(std::cin, journalEntry);

    // Append the date and journal entry to the file
    outFile << currentDate << "\n" << journalEntry << "\n" << std::endl;

    std::cout << "Your journal entry has been added." << std::endl;

    outFile.close();
    return 0;
}
