Haha thanks!

using this code:



char **maze;
maze = (char **) malloc(20 * sizeof(char *));

if(maze == NULL)
{
printf("ERROR cannot be allocated");

Nope switching it isnt the problem, products output like so.

11111111111111111111
11111111111111111111
11111111111111111111
11111111111111111111
11111111111111111111
11111111111111111111...

Here is my input for this code.

Example:


struct stackNode **xstack;
push(xstack, 5);
push(xstack, 5);


printf("%d %d", pop(xstack), pop(xstack));

Im getting crashes if I initialize more than one stack using this code.




struct stackNode{

int data;
struct stackNode *nextptr;
};

Hello, I have a task of solving a 20 by 20 maze. The problem im facing is that currently, I take a .txt file in and have to solve a maze for J amount of mazes.

Im having problems getting my if...

so should do something like

if(fscanf("%d", &array[i][j])

else(fscanf("%c", &array[i][j])

Ok gotcha, so if I didn't know when the character was going to be coming in how would I cast it to take the acsii code for the two letters while still taking in the integers?

I have a two dimensional array that will be taking in about 38 numbers and 2 letters randomly.


I allocate the memory for 20 columns and 20 lines and take in simple 1 digit numbers and two...

Ah yes, create some sort of a flag inside the loop to exit out or modify your while statement.

I know bubble sort has O(n^2) and that is really bad, anyone have an extremely fast way of going about this? (sorting LOTS of strings)

My question is:
What is the best algorithm for alphabetizing strings of chars in C?

try putting else in brackets?



else
{

printf("How many individual units of food do you wish to buy: ");
scanf("%d", &amount);

No compile errors or anything but wondering if thats bad style/practice.

Alright, I understand that

now does that apply for needing 2 elements per line

am I not allocating enough to have 2 elements(each with 30 chars) on x number lines?


should I

with the [0][0] though I get an error, only works with


scanf("%s %s", c2names[0]);


and that was a typo for the post should be


scanf("%s %s", c2names[0][0], c2names[0][1]);

ok

2 2
Hi there
my name
**

2 and 2 is the numbers that signify 2 rows. 2 columns

Well heres what is going on in my head,

I want to take in say 10 lines and 2 words per line (seperate)

so


char **c2names;

c2names = (char **) malloc(amount_of_lines * sizeof(char *));

yes but what if I want to take in 2 words

correct way to call it would be


scanf("%s %s", c2names[0][0], c2names[0][0]);

?

Here is what I basically need:

I need to be able to take in say 2 words on 10 lines
each word can be a maximum of 30 chars

heres what I have but it seems incorrect:


char **c2names;...
