Previous Exercise: The Largest of Three Numbers with the Conditional Operator
Next Lesson: Week 4: Increment, Decrement, and Bitwise Operators

Odd or Even with Bitwise AND

Easy

Read an integer and print one line of the form 7 is odd or 10 is even. Decide with the bitwise AND operator, not with %: an integer is odd exactly when its lowest bit is 1, and n & 1 isolates that bit. Choose the wording with the conditional operator ?: inside the printf call. If the integer cannot be read, print invalid input and return 1.
