[Dev-C++] Help with functions

From: Mansoor N. <man...@sy...> - 2001-10-02 23:14:50

Does any one know the functions for :

Generating a random number (integer) between a given range.

Extracting a character from a string:  eg:

( "HELLO", 4  )

that should output the fourth character : L

Any help would be appreciated

#include <stdlib.h>
#include <time.h>

int x;
/* Use this one time anywhere in the program  only */
srand(time(NULL)); 

x=rand(); /* One value between 0 and RAND_MAX, the most (and usually)
32767 */
x=rand();
...

After all literals are const arrays. :)
