UMBC CMSC201, Computer Science I, Fall 1994 Sections 0101, 0102 and Honors

Thursday October 13, 1994

Assigned Reading: 5.4 - 5.5

Handouts (available on-line): none

Topics Covered:

• Attendance was taken. This is worth 1% of your final grade.
• Trace through another example of function calls from a previous midterm exam. The question and solution.
• Reviewed the importance of using function prototypes. Here's a program that doesn't use function prototypes. Strange output is produced. The modified program works correctly when the function prototype for add3 is put in (sample run of the corrected program).
• A function that computes the value of a raised to power b. Program and sample run. If you typed man exp in UNIX, you would have noticed that there is already a function (called pow) that computes a raised to the power b. The manual entry for "exp" begins with an explanation of "exp" for FORTRAN, ignore this.
