Solution for Exercise 19-15

ex1915

#include <stdio.h>

int main()
{
    char *sample = "From whence cometh my help?\n";

    while(putchar(*sample++))
        ;
    return(0);
}

Output

From whence cometh my help?

Notes

* As the code manipulates the sample pointer in Line 7, its value changes. Effectively, the original location stored in sample is lost. So if I wanted to re-display or manipulate the string later in the code, I would be unable to use sample again. (Well, I could, but it would require way too much math and guessing and more overhead that could simply be avoided by not declaring the string by using a pointer.)
