print()

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

# In the context of strings, + is used for concatenation
# You can glue two strings together but not a string and a number.

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

a = "fire"
b = "fighter"
c = a + b

print( "a =",     a )

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" )
