[solved] – Question 99410
Type a statement using srand() to seed random number generation using variable seedVal. Then type two statements using rand() to print two random integers between (and including) 0 and 9. End with a newline. Ex:
5
7
Note: For this activity, using one statement may yield different output (due to the compiler calling rand() in a different order). Use two statements for this activity. Also, after calling srand() once, do not call srand() again.

[solved] – Question 99415
Re-type the code and fix any errors. The code should convert non-positive numbers to 1.
if (userNum > 0)
cout << “Positive.” << endl;
else
cout << “Not positive, converting to 1.” << endl;
userNum = 1;
cout << “Final: ” << userNum << endl;

[solved] – Question 99416
Write multiple if statements:
If carYear is before 1968, print “Probably has few safety features.” (without quotes).
If after 1971, print “Probably has head rests.”.
If after 1990, print “Probably has anti-lock brakes.”.
If after 2002, print “Probably has tire-pressure monitor.”.
End each phrase with period and newline. Ex: carYear = 1995 prints:
Probably has head rests.
Probably has anti-lock brakes.
