Question about Sorting Strings

[Timothy Chan]

I am taking C program course and i got some problem about sorting strings, hope someone could help me to solve the problem...

The is the output which suppose to be:
-------------------------
car
house
antidisestablishmentarism
another line of text
C programming is interesting
apple sauce
pumpkin pie
cable TV news
drink of water
yet one more line of text!
1) Print list of strings in the order input.
2) Print list of strings in the reverse order input.
3) Print list of strings in order of length.
4) Quit

-------------------
Enter: 3
Sorted Line #0: C programming is interesting
Sorted Line #1: yet one more line of text!
Sorted Line #2: antidisestablishmentarism
Sorted Line #3: another line of text
Sorted Line #4: drink of water
Sorted Line #5: cable TV news
Sorted Line #6: pumpkin pie
Sorted Line #7: apple sauce
Sorted Line #8: house
Sorted Line #9: car
1) Print list of strings in the order input.
2) Print list of strings in the reverse order input.
3) Print list of strings in order of length.
4) Quit
-----------------------

just want to ask how could i set different quote into different array, so i could compare them?

The strings are not supposed to be sorted.

What you are to do is print the strings in the order in which they were entered. This has nothing to do with the contents of the string.

So put the strings in an array as you enter them and then just display the array front to end and end to front.

Post again when you have this working. Then we'll talk about displaying by length.

is that mean..

 
if (option = 1 )
{
 printf("car");
 printf("house ");
}
 
if (option =2)
{
 printf("yet one more line of text!");
}
 
 

since i am not that good at C program...
hope you can explain to me more detail...

If you enter these strings:

car
truck
airplane

then in reverse order these are

airplane
truck
car

If these were sorted by value you would have:

airplane
car
truck

But you are not being asked to do this.

[Timothy Chan]

in stead of using the simple method like using [printf]

how do i set [car, truck,airplain] into strings?

Is that original list of strings (car, house, ..., yet one more line of text!) supposed to be typed in by the user or do you think it is ok to "hard-code" that list into your program?

Never mind. I suggest you start by writing functions that accept an array of strings and produce the three kinds of outputs. Whether your main program populates that array from user input or a hard-coded initializer has no impact on the lower level function. Start with a hard-coded initializer so you can focus on the lower level functions. Change it later if you wish.

static const char * const array[] = {
   "car", "house", ..., "yet another line of text!" };
static const int arraysize = (int) (sizeof(array) / sizeof(array[0]));

do you know how to sort a number array??

have you seen the bubble sort??

If you understand bubble sort then ask. I believe you will get help from people over here about how you can effectively use bubble sort to sort your string array. (Bubble sort is the simplest of all sorting)

[Timothy Chan]

never heard it before... may be i have learn something similar...
how do i use it to get the out put in order?

[donbock]

Review the replies from weaknessforcats. Option 1 calls for printing the strings in the order of input; no sorting required. Option 2 calls for printing the strings in the reverse order of input; no sorting required. Option 3 calls for printing the strings in order of length; here you will have to sort.

Get options 1 and 2 working first before you worry about sorting. Where do you stand on those?

[Timothy Chan]

this is what i have right now, is it correct?

#include <stdio.h>
#include <string.h>
#include <stdbool.h>
 
 
{
printf("car\n", "house\n", "antidisestablishmentarism\n", "another line of text\n",
       "C programming is interesting\n", "apple sauce\n", "pumpkin pie\n",
        "cable TV news\n", "drink of water\n", "yet one more line of text\n");
printf(" 1) Print list of strings in the order input.\n" , 
       " 2) Print list of strings in the reverse order input.\n",
       " 3) Print list of strings in order of the length\n");
char c=getcher();
 
if ( c == 1)
{
static const char array[] = (
 "car", "house", "antidisestablishmentarism", "oanother line of text", 
 "C programming is interesting", "apple sauce", "pumpkin pie", 
 "cable TV news", "drink of water", "yet one more line of text");
 static const int arraysize = (int) (sizeof(array)/ sizeof(array[0]));
) 
}
