Simple shader code reading C++

// Reading Files
std::string vertexCode;
std::string fragmentCode;
std::ifstream vShaderFile;
std::ifstream fShaderFile;

vShaderFile.exceptions(std::ifstream::badbit);
fShaderFile.exceptions(std::ifstream::badbit);

    fShaderFile.open(fragmentFile);

    vShaderStream << vShaderFile.rdbuf();
    fShaderStream << fShaderFile.rdbuf();

    vShaderFile.close();

    vertexCode = vShaderStream.str();
    fragmentCode = fShaderStream.str();
}
catch(std::ifstream::failure& e) {
    std::cerr << "ERROR::SHADER::FILE_NOT_SUCCESFULLY_READ" << std::endl;
    return nullptr;
