Sure! Here is a simple program in Python to determine which of the two numbers is greater:

# Input two numbers
num1 = float(input("Enter first number: "))
num2 = float(input("Enter second number: "))
# Compare the two numbers and print the result
if num1 > num2:
print(f"{num1} is greater than {num2}")
elif num2 > num1:
print(f"{num2} is greater than {num1}")
else:
print("Both numbers are equal")

You can run this program in any Python IDE or online compiler by entering two numbers and it will tell you which number is greater.
