@nandini look at the heart of each flower and the base. The thin long ones which have a 'male' shape, are the male flowers. The ones with a bulbous base which have a more wriggly stamen on the inside of the flower, is the female. I'm rather crude and I put the male stamen in the female and it never lets me down!
Pumpkins are coming along nicely, 2nd leaf is coming through. #halloween
