Hey, I am just wondering if anyone on here knows c++.

I have got a piece of coursework to do for the 10th of April that requires a random number generator and the ability to save and re-call the numbers. now as I have never used a R.N.G before I am absolutely stumped. I can get it to generate the numbers but can't quite seem to figure out how to store them.

Any help is appreciated.

*edit*

almost forgot, this is the generator I am using.

Code: Select all

    {
    srand((unsigned)time(0));
    float lowest=-10, highest=10;
    float range=(highest-lowest)+1;
    for(float index=0; index<8; index++){
        rw1 = lowest+float(range*rand()/(RAND_MAX + 100));
        cout << setprecision(2) << setiosflags(ios::fixed);


        cout << endl;
        system ("pause");

        }

I wish I could help, but I don't know much of C++. I use Python for most of my programming.

Good luck with it, though.

I haven't used C++ in over 4 years, I can't remember a thing about it, sorry

funny, looks like that code isn't printing anything.

Okay, the easiest way to store the random numbers is either in an array or a linked list.

the current code:

Code: Select all

for(float index=0; index<8; index++){
        rw1 = lowest+float(range*rand()/(RAND_MAX + 100));

updated code

Code: Select all

for (float index=0; index<8; index++){
    randomArray[index] = lowest+float(range*rande()/RAND_MAX + 100);


just make an array of whatever number of objects you need and save the random number directly to it. Obviously, you need to create the array first. hope that helps.

Damn, I learned C++ and Java a year and a half ago and forgot most of it. Hence why I'm not a programmer anymore.

Don't feel bad. I've got a degree and I still had to look up my old homework to remember that.

yeah...i just realised i forgot to paste in the part that shows the numbers..


thanks for the help man....much appreciated.
