C Programming Tutorial 57, Generating Random Numbers

[wiings]

11 years later, a lot of Adam's work here is still relevant. It's a great help in a software dev't program I'm in. Asante sana

Wow, amazing C programming tutorial set!!! Thank you very much for putting in the effort, I truly appreciate it. I just wanted to give you a shout out and say thanks, it's the least I can do. A truly incredible job.

Thanks again!

The / operator just does straight up division, so 10 / 2 = 5. The % operator performs the modulus operation. So it divides the numbers, but gives you back the remainder. So 10 % 2 = 0 because 2 goes into 10 evenly so there would be a remainder. 11 % 2 would give us 1 since 2 does not go into 11 evenly, there's 1 left over.

Why are there no cutely brackets around the printf function after the for loop?

[BluemoeNYJ]

Great explanation man. Thank you so much.

Hi Adam, why cant u put the srand into the for loop?

[Elec-DIY]

The same here:
'for' loop initial declarations are only allowed in C99 mode use option -std=c99 or -std=gnu99 to compile your code, if I can make it work I'll tell you.

Is it possible to make void variables(possibly that store NULL or something)?

[iestyngrills]

how do you eliminate duplicate numbers being
generated??

[RamonBlanquer]

Thank you very much for the explanation!

[thewhisperinyourears]

Wait Wait!!! confused how is you use % for dividing and not the / sign with %?

[alexp]

function 'main':|
'for' loop initial declarations are only allowed in C99 mode|
use option -std=c99 or -std=gnu99 to compile your code|
||=== Build finished: 1 errors, 0 warnings (0 minutes, 4 seconds) ===|

I get this when compiling and running.

I want that random number just show only from 1->10... Tell me how.. Thanks

[Nettaphone]

do this if you get the "c99 whatever" error:
int main()
{
int i;
for (i = 0; i < 10; i++)
printf("%i\n", rand());
return 0;
}

Why are there no curly brackets around the printf function after the for loop?
