The book is terrible in most parts, but this is a nice llittle thing it did. It demonstrates how to go about generating random numbers using the computers time. #include #include #include int rnd(int range); int seedrnd(void); void main(void) { int x; seedrnd(); for (x=o;x<100;x++) printf("%i\t",rnd(10)); } int rnd(int range) { int r; r=rand()%range; return(r); } void seedrnd(void) { srand((unsigned)time(NULL)); } On Wed, 04 Jun 1997 14:14:47 -0400, "A.
