#write a function that has one parameter and function returns the 
#square of the parameter

#call your function square

#for example square(5) will return 25
#square(9) will return 81
#square(-4) will return 16

#write a program (main)  that reads 10 integers
#and program prints the square of each input number
#use LOOP in main

def square(a):
	return a*a #a**2

def main():
	for i in range(10):
		num=int(input("enter int "))
		print(num,"^2=", square(num))
main()
