Ruby on Rails

It is OK to use assignment in a conditional test. Assuming x = 0 already, the following two conditional expressions produce the same outcome:

if x = 0 puts CIS199; end 

if x == 0 puts CIS199; end 

True

False

When comparing two strings, string1 and string2, with ==, the following statement compares both strings character by character:

string1 == string2

True

False

It is syntactically correct to have a case statement without a test expression such as the following

case when x == y puts CIS199" end

True

False
