Relational operators

• These behave as you expect them to, and appear syntactically similar to how you may recall them from elementary arithmetic.

  • Less then (x < y)
  • Less then or equal to (x <= y)
  • Greater then (x > y)
  • Greater then or equal to ( x >= y)

• C also can test two variables for equality and inequality

  • equality (x == y) inequality (x != y)

• Be careful! It's common mistake to use the assignment operator (=) when you intend the equality operator (==)
