How to Ask a Programming Question

Anyone can ask a question in our programming channels. Following the guide Writing The Perfect Question is recommended.

What to Post

State your problem clearly and provide all necessary details:

• the relevant portion of your code, or all of it
• the expected output
• the actual output (or the full error)
  :trophy: Gold Standard: Minimal Reproducible Example

Where to Post

Provide the relevant code in the message, and format it nicely with a code block*. If it's too much for one message, you can upload it:

• Compiler Explorer for most C/C++ snippets
• OnlineGDB for interaction, debugging
  :no_entry: Do not post screenshots, let alone photos of your screen!

* Use /code if you don't know how to format code blocks

like

std::streampos getFileSize(const std::string& filename) {
    std::ifstream file(filename, std::ios::binary | std::ios::ate);
    if (!file.is_open()) {
        std::cerr << "Unable to open file: " << filename << std::endl;
        return -1; // Indica erro
    }
    return file.tellg(); // Retorna o tamanho do arquivo
}

std::vector<char> readFileData(const std::string& filename) {
    std::ifstream file(filename, std::ios::binary);
    if (!file.is_open()) {
        std::cerr << "Unable to open file: " << filename << std::endl;
        return {}; // Retorna um vetor vazio em caso de erro
    }

    // Obtém o tamanho do arquivo
    std::streampos fileSize = getFileSize(filename);
    if (fileSize == -1) {
        return {};
    }

    // Lê os dados do arquivo para um vetor de char
    std::vector<char> fileData(static_cast<size_t>(fileSize));
    file.read(fileData.data(), fileSize);

    return fileData;
}

i found this and i test it and it gave me random bytes. i know its suppose to but i dont know if the function is correct

teh second function

the first is right

[pastel lava]

if you only want to read file, i like this way```cpp
std::ifstream t("input.txt");
std::string str((std::istreambuf_iterator<char>(t)),
std::istreambuf_iterator<char>());

add #include <fstream>

ok thanks i ll check it out
