Practical C Programming, 3rd edition
by Steve Oualline


Following are the changes made in the 4/00 reprint:


(59) Question 4-2: 
        "Why is the result of Example 4-4 "0"?"
now reads 
        "Why is the result of Example 4-4 "0.0"?"


{151} Example 10-10:
        for (counter = 0.0
now reads
        for (counter = 1.0


{169} 1st paragraph:
"2" is now subscripted (2 instances)

{172} 2nd & 3rd paragraphs:
"2" is now subscripted (4 instances)


{182} 
Added the following sentence before "Summary":

	"The state field is two elements because it is designed to hold
	two characters.  The field is not a string because we have
	not allocated enough space for the end of string character
	('\0')."



{192} Example 13-3, 3rd line:
        char array[ARRAY_SIZE] = "0123456789";
now reads
        char array[ARRAY_SIZE + 1] = "0123456789";


{196}
        ...from the source (p) to the destination (q).
now reads
        ...from the source (q) to the destination (p).


{241} Example 15-6 has been changed to read:

1 #include <stdio.h>
2 char line[100];     /* line of input */
3 int seven_count;    /* number of sevens in the data */
4 int data[5];        /* the data to count 3 and 7 in */
5 int three_count;    /* the number of threes in the data */
6 int index;      /* index into the data */
7
8 int main() {
9
10     seven_count = 0;
11     three_count = 0;
12     get_data(data);
13
14     for (index = 1; index <= 5; ++index) {
15
16         if (data[index] == 3)
17             ++three_count;
18
19         if (data[index] == 7)
20     ++seven_count;
21     }
22
23     printf("Threes %d Sevens %d\n",
24             three_count, seven_count);
25     return (0);
26 }
27
28 void get_data(int data)
29 {
30
31     printf("Enter 5 numbers\n");
32     fgets(line, sizeof(line), stdin);
33     sscanf(line, "%d %d %d %d %d",
34         &data[1], &data[2], &data[3],
35         &data[4], &data[5]);
36 }


{292} Figure 17-9, top:
        new_ptr->next_ptr
now reads
        new_ptr->previous_ptr
