Okey i have cleaned the code and organised it , i have tried somethign but it didnt worked

I have tried to definne the fonction like this and thats doesnt work
void loop()
{
getHumidityReading = DHT.humidity
getTemperatureReading == DHT.temperature
auto humidity = getHumidityReading();
auto temperature = getTemperatureReading();
auto image = takePicture();
auto imageFilename = generateImageFilename();
storeImageToSdCard(imageFilename, image);
auto sensorValuesFilename = generateSensorValuesFilename();
storeSensorValuesToSdCard(humidity, temperature);
}
he create the file but dont do anything more
