Solution for Exercise 19-18

ex1918

#include <stdio.h>

int main()
{
    char *fruit[] = {
        "watermelon",
        "banana",
        "pear",
        "apple",
        "coconut",
        "grape",
        "blueberry"
    };
    int x;

    for(x=0;x<7;x++)
    {
        putchar(**(fruit+x));
        putchar('\n');
    }

    return(0);
}

Output

w
b
p
a
c
g
b

Notes

The first letter of each string is output. The expression **(fruit+x) represents a character, not a string. If you keep in mind that *(fruit+x) is the memory location of the string, the initial * is reading the contents of that location, a character.
