# get Celsius temperature c

reply = input( 'Enter Celsius temperature: ' )

c = int( reply )

print( )

# compute respectively, f1 and f2, the decimal and integer Fahrenheit equivalents of c 

# Order of Operations: Multiplication/division before addition/substraction
f1 = 9/5 * c + 32

# f2 = 9//5 * c + 32

f2 = 9 * c // 5 + 32

# Be careful where you do division/multiplication
# to get the right result!

# Why 9//5 * c + 32 doesn't work:
# 9/5 = 1.?? = integer of 1.?? is 1!

# display results

print( c, 'C =', f1, 'F' )

print( )

print( c, 'C =', f2, 'F' )
