Question

Помогите доработать код С++ В файле text.txt дана одна строка - текст сообщения. Автор забыл поставить в конце точку. Запишите в файл res.txt сообщение с точкой на конце. #include #include #include using namespace std; int main() { char str [100]; ifstream fi ("text.txt "); ofstream fo ("res.txt"); fi >> str; fo << str << "."; } выдаёт рандомные символы

Code Explanation and Issue

The provided code is written in C++ and aims to read a single line of text from a file named "text.txt" and write the same text to another file named "res.txt" with a period (.) added at the end.

However, the code seems to have a syntax error and is not functioning correctly. When executed, it produces random characters instead of the expected output.

Code Correction

To fix the code, we need to address the syntax error and ensure that the file operations are performed correctly. Here's the corrected code:

#include 
#include 
using namespace std;

int main() {
    char str[100];
    ifstream fi("text.txt");
    ofstream fo("res.txt");

if (fi.is_open() && fo.is_open()) {
        fi.getline(str, 100);
        fo << str << ".";
        fo.close();
        fi.close();
        cout << "Message with a period added at the end has been written to res.txt." << endl;
    } else {
        cout << "Failed to open the input or output file." << endl;
    }

return 0;
}

Explanation of the Corrected Code

1. The necessary header files, `iostream` and `fstream`, are included. 2. The `using namespace std;` statement is used to avoid writing `std::` before standard library functions. 3. The `main()` function is defined. 4. An array `str` of size 100 is declared to store the text from the file. 5. Objects `fi` and `fo` of the `ifstream` and `ofstream` classes, respectively, are created to handle file input and output operations. 6. The `is_open()` function is used to check if the input and output files are successfully opened. 7. If both files are opened successfully, the `getline()` function is used to read a line of text from the input file into the `str` array. 8. The modified text with a period added at the end is written to the output file using the `<<` operator. 9. The input and output file streams are closed using the `close()` function. 10. A success message is displayed if the files are opened and processed correctly, or an error message is displayed if there was a problem opening the files. 11. The `main()` function returns 0 to indicate successful execution of the program.

Additional Notes

Make sure to place the "text.txt" file in the same directory as the program file before running the code. Also, ensure that you have write permissions for the directory to create the "res.txt" file.
