}- The following is one of many possible answers:
/ random.c: using a single-dimensional array /
#include <stdio.h>
#include <stdlib.h>
/ Declare a single-dimensional array with 1000 elements /
int random[1000];
int a, b, c;
long total = 0;
int main( void )
{
/* Fill the array with random numbers. The C library */
/* function rand() returns a random number. Use one */
/* for loop for each array subscript. */for (a = 0; a < 1000; a++)
{
random[a] = rand();
total += random[a];
}
printf(“\n\nAverage is: %ld\n”,total/1000);
/* Now display the array elements 10 at a time */49 448201x-APP F 8/13/02 11:22 AM Page 849
