Very good, clear and simple explanation !!! good job...

I also saw this line srand(time(NULL)); on top of the main function for this to not generate the same number all the time

[leythecg]

Once again brought to the point without much fuss! Thank you very much! 👍👍👍

[safa-ucmk]

Thank you mister! That was a really crisp explanation 🙌

[carljohncafe]

Thank you so much! This video is a life saver.

[EbyHamady-ulrc]

It was a really excellent and calm explanation, thank you

How would you go about reading a user input in the range of numbers? For example, if you wanted them to pick a number 1 - 10. How could you make it so it reads if they picked within that range?

[lydianne]

Thank u so much i have an exam tomorrow and i don't understand this function . U save me ❤❤

[omarmohammed]

So if I wanted to generate random number from 0 to 12

Then i do this right?
Cout<< rand()%12<<endl;


Without the 1 .

[youssefkawtharani]

What if i want the user to enter a random number and the program should tell true or false?

[MmedKasem]

You look charismatic, however can pull off the goofiest face in the party at anytime.

You shoulda wrote the textbook im using for class right now. I don’t know how the author is gonna just drop rand/srand in an example program without context and be like:
“Edit the program so it displays 1-10”

Like nah thats not how it works chief
