Yeah, I noticed that right after I posted. However, I've changed that now, to no avail. -
More problems with string manipulation and seg faults
Alright, here's what I'm working on now. It's supposed to go through an inputted list of words, pick out actual words and create a numbered list of them, then, where it finds a number in the list, go back in the list from that number, replace it with a word, augment the list accordingly and continue.
Anyways, here's what I have:
...Code:#include <stdio.h> #include <string.h> #include <ctype.h>
-
NVM, I solved the initial problem, but I have a new one, which will be posted in a second.
Anyways, strtok(NULL, " ") takes a string and seperates it based on where the spaces are. So, if the input was char test = {"These are a bunch of words."}, it would seperate it into "These", "are", "a", "bunch", "of", "words."
Anyways, new problem:...Leave a comment:

Help with tokenizing
Ok, the program I'm working on now involves taking an input string and tokenizing it, by seperating it by spaces. Here's what I've got:
...Code:#include <stdio.h> #include <string.h> int main (void) { char *tokenarray[100]; char input[200] = {"Test , Test2"}; char *tokenPtr; int cnt = 0; tokenPtr = strtok(input, " -
Problems with file reading and strings
Alright, as a continuation of my previous question, I've got two problems with this program-the file read only reads the last line of the input file, and, when I try to assign a tokened word to a spot in the array, it returns a segmentation fault. Anybody know what I'm missing?
...Code:#include <stdio.h> #include <string.h> int main (void) { FILE *file; file = fopen("input2.txt", -
Help with reading in a string from a file
I'm working on a program that, eventually, is supposed to uncompress a text file where words are replaced by numbers. However, before I get to that part, I need a hand with reading in the text from a file and parsing it with strtok. Here's what I've got so far:
...Code:#include <stdio.h> #include <string.h> int main (void) { FILE *file; file = fopen("input2.txt", "r"); -
Ah, thanks DeMan, that was half the problem, and I realized the other half.
The correct version is:
...Code:int BubbleSort (int numlist[], int size, int order) { int pass, num1, num2; int cnt; for (pass = 0; pass < size - 1; pass ++) { for (cnt = 0; cnt < size - 1; cnt ++) {Leave a comment:

Normally, I would and all would be well, except that the prof has specificed that we can't use Array[] anywhere other then the declaration of the array.Leave a comment:

sicarie-an incorrect value, namely the unsorted array. And the return 0; was a brain fart (It was originally in main before I reorganized the program-I just forgot to delete it!) However, removing it doesn't do anything.
RedSon:
Here's the call in main that calls the sort:
...Code:case 3: printf("Please enter the size of the array: "); scanf("%d",Leave a comment:

Yeah, sorry I wasn't more clear about it. The problem is that...well, it doesn't work. I think the problem is with the if ((numlist + cnt) > (numlist + cnt + 1)) and if ((numlist + cnt) < (numlist + cnt + 1)) statements-I think they don't cycle through the array properly.Leave a comment:

Arrays and Pointers
I'm currently working on some more stuff for an assignment, this time with pointers. The current task is to bubble sort an array using a extrnal swap function that uses pointers, and to reference the array without using the Arrayname[] operator.
Anyways, here's what I've got:
...Code:int BubbleSort (int numlist[], int size, int order) { int pass, num1, num2; int cnt; for (pass -
That would be correct.Leave a comment:

Yeah, bubble sort is a requirement, else I'd use something more efficient.
It's a 2D array, in that is starts off as an X by Y array of random variables (The row and column variables are passed in as a and b, respectively.) I'm trying to get it to sort in increasing order.
Anyways, here's what I'm trying to get it to do:
While (cycling through the array)
If (Array[x][y] > Array(Next variable,...Leave a comment:

2-dimensional array bubble sort
Hey, I'm working on a project that involves sorting a two-dimensional array of integers using bubble sort. I've got it semi-working, my only issue is that it seems to be 'losing' values, I'm assuming when it gets to the end of a line in the array. It also has to run several times to get the values it keeps in completely correct order.
Here's what I've got so far:
...Code:int SortArray (int Array[][N], int a, int b) { -
Help with Pancake Sorting
Alright, I'm working on a pancake sorting program, and I'm currently working it to try and switch the position of the first and the largest numbers, then invert the array. Anyways, here's what I have ATM:
...Code:#include <stdio.h> void main (void) { int array[5], temparray[5], f, g, l, flip, lgp, lgn = 0; printf("Please enter the numbers: "); for (f = 0; f < 5; -
Alright, I've made the modifications, and got parts of the array to flip. Now, the next part.
By the way, I'm supposed to be working towards creating a Pancake Sorting program, so if anybody has any help at all for that, I'd love to see it.
Anyways, here's my next hurdle-I'm trying to get it to find the largest number, have it switch places with the first number, then invert the whole array. As usual, here's what I have:...Leave a comment:

Alright, here's what I've got so far for it:
...Code:#include <stdio.h> void main (void) { int array[5], temparray[5], f, l, flip; printf("Please enter the numbers: "); for (f = 0; f < 5; f ++) { scanf("%d", &array[f]); temparray[f] = array[f]; }Leave a comment:

Flipping a section of an array
Hey, another question. How do you flip a section of a one-dimensional array? For example, you have array[5] = {1,2,3,4,5}, and I want to flip the last 3 numbers, to produce array[5] = {1,2,5,4,3}.
Any help would be much appreciated! -
Beautiful, thanks!
Knew it was something small like that.Leave a comment:

A (likely really simple) random number generator question
Preface: Yes, I know. I'm a noob. I'm currently in an Intro to Programming class at university. So, I'm betting everybody here can answer this question, and I'm gonna feel silly for not knowing the obvious answer. But, hey, whatever gets my assignments done.
Anyways. Here's part of an assignment I'm working on:
...Code:#include <stdio.h> #include <time.h> int rand(void); void srand(unsigned
