Solution for Exercise 11-19

ex1119

#include <stdio.h>
#include <stdlib.h>

int main()
{
    unsigned seed;
    int r,a,b;

    printf("Input a random number seed: ");
    scanf("%u",&seed);
    srand(seed);
    for(a=0;a<20;a++)
    {
        for(b=0;b<5;b++)
        {
            r=rand();
            printf("%d\t",r);
        }
        putchar('\n');
    }
    return(0);
}

Notes

* The %u in the scanf() function ensures that only positive integer values are input.
