Pick Algorithm

This is the module that will pick a random number between 1 and 100.

1. Pick a random number

2. make sure it is between 1 and 100

3. return pick

C provides a function to generate a random number, called rand(). The prototype is in <stdlib.h>:

     int rand(void);

It is given nothing (that's what void means), and returns a random integer. Unfortunately, the number is in the range 0 to the maximum positive integer we can represent (about 2 billion).

Let's look at the code in class to see how this is done.

example function

int pick (int start, int stop){

//int x = rand();

int y = (rand()%(stop - start+1))+start;

return y;

}
