The code button is ok for small extracts but the recommended way for larger sketches is shown at [README] Welcome to Blynk Community!
You then get colour formatted code like this:
Serial.begin(115200);
Serial.println(F("\Starting"));
WiFi.hostname("EEPROMhandler");
EEPROM.begin(100); // max 512 bytes of EEPROM starting at address 0
DataLocation = 1; // e.g. for Blynk token
EEPROMgetE(DataLocation, theData);
delay(50);
