Hello,

I have generated a group of random numbers but I can not figure out how to display the numbers in groups of 4. Any suggestions?

``````srand ((unsigned int) time(NULL));
int i, high, low, number;
high = 47;
low = 19;
for (i=0; i<20; i++)

{

number = rand() % (high-low+1) + low;//
cout << number << endl;

}//end for i

frz;
return 0;
} // end of main function``````

There are two very simple ways of doing this:

• To actually do the number=rand, cout stuff 4 times or..
• To use another for loop.

``````int main()
{
srand ((unsigned int) time(NULL));
int i, high, low, number;
high = 47;
low = 19;
for (i=0; i<20; i++) {
number = rand() % (high-low+1) + low;
cout << number << " ";      //changed
}
}//end for i

frz;
return 0;
} // end of main function``````

This will output in the following manner:

``````42 30 20 28
21 38 45 25
23 21 39 35
...
and so on.``````

You just need to add a newline the moment you have displayed four randoms.

``````for(int i = 0; i < 100; ++i)
{
if(i % 4 == 0)
putchar('\n');
cout << randomNumber;
}``````

Nick, I entered to code and my results were 4 colums of 20 #'s, not 5 columns of 4 #'s. Any suggestions?

Yep, I misread the question. ~s.o.s~'s suggestion to simply add a newline when n mod 4 is 0 (ie n is a multiple of 4) will work. This seems to be what your tutor suggested from the PM you sent me.

Thank You s.o.s & Fatnickc..........you guys are awesome!
