Calculating the mean of positive and negative numbers
Implement a program that reads 12 real numbers and calculates the mean of the positive and negative numbers. Afterwards, the result must be displayed to a maximum of 4 decimal places. Run the following test cases to test your program:
| test case ID | inputs | expected outputs | |
|---|---|---|---|
| mean of positives | mean of negatives | ||
| 1 | 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12 | 6.5 | 0 |
| 2 | -1, -2, -3, -4, -5, -6, -7, -8, -9, -10, -11, -12 | 0 | -6.5 |
| 3 | 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 | 0 | 0 |
| 4 | 12.4, 21.005, -3.67, 4.43, 5.56, 4.2, 7, 8.3, -91.3, -1.0, 32.4, 12.1 | 11.9327 | -31.99 |
Insist that the students test their programs by giving them example
test cases in a table. Series with only positive numbers, series
with only negative numbers, all zeros, and mix of positive/negative.
