C Question & Java Questions

1. On C & Java - How can i make a size-limited random number (between 1-100 for example)?
2. On Java - How can i use icons in JTextArea?

 

Random number:

Code:

#include <cstdlib>
#include <ctime>
#include <iostream>

int minVal = 1, maxVal = 100;
srand(unsigned(time(NULL)));
int RandomNumber;
    for(int i=0; i<10; i++)
    {
        RandomNumber =  minVal + rand() % (maxVal);
        cout << RandomNumber << endl;
    }

sure there are other ways of doing it, but if I want one for whatever reason thats the way that I do it...

Not sure about your other question...

hope thats some help

why using loop for this? and what is that line with "<<" means?

 

sorry, I usually want to generate more than one random number:

Code:

#include <cstdlib>
#include <ctime>

int minVal = 1, maxVal = 100;
srand(unsigned(time(NULL)));
int RandomNumber;
        RandomNumber =  minVal + rand() % (maxVal);
        cout << RandomNumber; //that just outputs it to the screen (just used one of my old peices of code) you dont need this...
