What has possibly gone Wrong?

Question

Please see my code - What is Incorrect?? How?? Why??? for relevant details...
Please Help...

Answer 1

rand()%upper returns a random number in 0 to (upper-1). You are adding low (25) to it thereby resulting in out of range numbers.

Answer 2

@Kinshuk : If range is 25-30, you have to use (25 + (rand()%5)). But you are using (25 + (rand()%30)).

Answer 3

@Luka
???
I had set the range to 25-30, as the format is :
lower_limit+(rand()%upper_limit)

Answer 4

And Thank You , Luka

Answer 5

@Krishna Teja Yeluripati
But sir, lower is added to get range of lower->upper-1?
Its there in the c++ tutorial?!

Answer 6

So we have to mod rand() with the difference of upper and lower?
They haven' explained this on the tutorial at least...

Answer 7

Thank You, Sir

Answer 8

Why haven't they explained much about limits?
This is even wrong in the C++ Book i have and on a few sites...

Answer 9

Guess it will be better to use random()...
