Question about pseudo random numbers

[hmlewis]

I have a program that allows a user to guess a number 5 times. How can I create the number using a pseudo random number rather than "pre-defining" the numbers. The number has to be between 1 and 20??

Any help would be greatly appreciated.

Have a look at the srand() and rand() functions; they're part of the standard library.

kind regards,

Jos

[curiously enough]

#include<stdlib .h>//contains random functions and RAND_MAX
#include<time.h >//contains time
srand(time(0));
number=rand()%2 0+1;

You know, you don't have to post this question here and wait till(or if) someone answers it, you can just google it.
