NEWBIE OLED For Variable Question

Coming from a new environment.

I have a for loop outputting the index counter to oled. I'd like 0 through 9 to display the leading zero. (ie 01, 02, 03, 04)

for (int counter = 0; counter < 10; counter++) {

twi.begin(4, 15);
display.begin(SSD1306_SWITCHCAPVCC, 0x3C);
display.clearDisplay();
display.setFont(&FreeMonoBoldOblique12pt7b);
display.setTextSize(2);
display.setTextColor(SSD1306_WHITE);
display.setCursor(35, 50);
display.println(counter);
display.display();
delay(350);
}

Thanks.

display.print(“0”);
display.println(counter);

larryd:
display.print(“0”);
display.println(counter);
