Re: [Dev-C++] How do you get random numbers in devc++?

<html><div style='background-color:'><DIV>
<P>Well you could try something like this...</P>
<P>NOTE: These are in C so if anyone has the C++ version let me know!</P>
<P>int rnd(void)&nbsp;&nbsp; // Remember to declare elsewhere by typing int rnd(void);</P>
<P>{</P>
<P>int r;</P>
<P>r = rand();</P>
<P>return(r);<BR></P>
<P>}<BR></P>
<P>&nbsp;</P>
<P>Or you may like to "seed" the randomiser whereby you give it more numbers to base its calculations on and mess things up more (so it's "more" random).</P>
<P>void main()&nbsp;&nbsp;&nbsp; // Or int main()</P>
<P>{</P>
<P>&nbsp;&nbsp; int x;</P>
<P>&nbsp;&nbsp; seedrnd();</P>
<P>&nbsp;&nbsp; for(x=0;x&lt;100;x++)</P>
<P>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; printf("%i\t", rnd());</P>
<P>}</P>
<P>int rnd(void)</P>
<P>{</P>
<P>&nbsp;&nbsp; int r;</P>
<P>&nbsp;&nbsp; r=rand();</P>
<P>&nbsp;&nbsp; return(r);</P>
<P>}</P>
<P>void seedrnd(void)</P>
<P>{</P>
<P>&nbsp;&nbsp; int seed;</P>
<P>&nbsp;&nbsp; char s[6];</P>
<P>&nbsp;&nbsp; printf("Enter a random number:");</P>
<P>&nbsp;&nbsp; seed=(unsigned)atoi(gets(s));</P>
<P>&nbsp;&nbsp; srand(seed);</P>
<P>}</P>
<P>&nbsp;</P>
<P>There are easier ways of doing it of course, but I'll leave that for others to inform you.</P>
