What will be an ideal response?
Based on the dangling-else discussion , modify the following code to produce the output shown. Use proper indentation techniques. You must not make any additional changes other than inserting braces. We eliminated the indentation from the following code to make the problem more challenging
``` if (y == 8) if (x == 5) cout << "@@@@@" << endl; else cout << "#####" << endl; cout << "$$$$$" << endl; cout << "&&&&&" << endl; ``` a) Assuming x = 5 and y = 8, the following output is produced. ``` @@@@@ $$$$$ &&&&& ```
Which of the following statements regarding variance is FALSE?
A) Variance provides a more accurate picture of the dispersion of a data set than a range B) Due to the way variance is calculated, the value is not in the same units as the mean. C) Variance is most useful because its value is in the same unit as the median and therefore easier to interpret. D) The higher the variance calculation the more dispersed the data set.
