1. A common mistake for new students is reversing the assignment statement. Suppose you want to assign the value stored in the variable "pi" to another variable, say "pi2":
   1. What is the correct statement?
   2. What is the reverse? Is this a valid C statement (even if it gives incorrect results)?
   3. What if you wanted to assign a constant value (like 3.1415) to "pi2":

      a. What would the correct statement look like?

      b. Would the reverse be a valid or invalid C statement?

1. pi2 = pi;
2. The reverse, pi = pi2; is a valid C statement if pi is not a constant and pi2 is initialized.
3. a. pi2 = 3.1415;
   b. The reverse: 3.1415 = pi2; is not valid since it is impossible to assign a value to a literal.
