  • how value parameters are passed
  • why an expression can be used as an actual value parameter
  • The fact that a variable can be used as an actual parameter when the name of the variable is not the same as the name of the formal parameter.
  • understanding the scope of a local variable.
  • understanding that a called function cannot change the caller's copy of a parameter passed by value.

  • I will be away on Monday, March 19. The class will get started on lab assignment #4 in the lab (P-288) on that day. Lab assistant Ray Williams will be there to answer questions. I will give more information with the lab #4 directions soon. You will be finishing up lab #4 over a period of a couple of weeks, and you will not have to turn anything in related to lab #4 until the week beginning March 26.
• A note about the advantages of working with a partner: One of the good things about working with a partner is that X can work at the keyboard while Y checks what X is doing for "sanity." If we ever have a minor "crisis" in the lab, you may see two of the senior faculty and/or staff working like this. We do this because it is effective and necessary. (It's not just because we like each other :-)
• if-else and nesting if-else's. Look at sample functions. Guess the outputs.
