print()

# operator + when given two string operands produces their concatenation;
# i.e., a new string that is formed by running the two operands together

print( '### operator + performs concatenation' )

a = 'fire'
b = 'fighter'
c = a + b

print( 'a =', a )
print( 'b =', b )

print()

print( 'a + b =', c )

print()

# operator * when one of its operands is a string and the other is an integer,
# produces a new string that is a repeated concatenation of string operand
# indicated by the integer

print( '### * operator produces repeated concatenation' )

m  = 'Wahoo-Wah!'

mn = m * n
nm = n * m

print( 'm = ', m )
