Gaussian elimination is designed to solve systems of linear algebraic equations,
[A][X] = [B]

Yup, i had been extremely unlucky, it worked 100% of the times.

I see. Thanks Narue. I really appreciate this.

In your first example you used sprintf:
#include <stdio.h>

int main ( void )
{
char buffer[20];

sprintf ( buffer, "%d", 12345 );

itoa isn't a standard function, so it may not be available.

I tried to investigate the reason behind it and found this...

Just showing you how to extract digits one by one from an int

#include<stdio.h>

int main()
{
unsigned input, temp;
printf("\nEnter int: ");
scanf("%u",&input);
temp = input;

Looking forward to this.

this is causing the crash:
list_of_lists.InsertatLast(implicant_list);

and no my InsertatLast() doesnt take reference. By the way I might have made a mistake writing the copy constructor, please...

Run time error. I m sure it's related to pointers. Memory error to be specific.

I have a template linked list class, eg:
LinkedList<int> list1;
LinkedList<implicant> list_imp;
Now I need a Linked List of Linked Lists, This is how I declared
LinkedList<LinkedList<implicant> >...

Yes, segmentation fault has chased me long enough when i was learning pointers. Most of the time it gotta do something with the pointers or array. It occurs when...

I cant believe u r asking for help again after Narue just did the whole thing for u. You know which letter will stand at the end, only thing left for u to do is to display it. May be u should try...

According to Josephus problem the standing letter for 'flames' would be 'e', unless u r including the nul character u have in ur string. So r u considering 'flames' or 'flames\0' ?

Ha ha! There are so many ways to do it. The easiest process is to try divide the number with every number less than (or half of it) and see if it has the remainder 0. If it does then check if the...

Would have been better if it were a template class.

Great! Although a bit more comments would have made it an easy read for the beginners.

This is unbelievable. There is no reason to scuttle a project because someone used bubble sort. It just needs to be replaced with a better sorting algorithm and that's all. I am a moronic bobo but i...

First I would like to make ur bubble sort implementation a bit shorter so that it doesnt look bigger than ur insertion sort which i believe u did intentionally.

void bubble_sort(int array[], int...

Yes Bubble sort is the least efficient algorithm available.
However, for small data sets it doesnt matter much what sorting algorithm u use. And bubble sort does have a few good qualities. Apart...

Suppose i have a linked list of say integers. So whenever i add a new integer to that linkedlist i also:
1. calculate the hash code for that integer
2. add a pointer to that integer into the...

This is probably a stupid question, but i dont get the answer. Plz help me understand.

Question:
How could a linked list and a hash table be combined to allow someone to run through the list...

why is everyone so much into STL?
Did i not explain why i dont want to use STL? Cos i m not into it yet. My knowledge on C++ is limited. Well what the heck, i have done it by parsing -- seems like...

"EOF"
>>I did try that too. But the problem is when i signal the EOF it stops taking input alright but doesnt take any other inputs after that. Say after inserting the page numbers the user might...

Well i got ur point. Can u suggest me any other technique to read in the page numbers easily one by one untill we meet some "end condition". What would be a smart end condition?

I do have a linked list of integers and i have to insert the page numbers into it, but thats not the problem --the problem is about the end condition when it will stop inserting.

To Jwenting,
ahem ahem,:rolleyes:
Thanx for that boss,BUT
i havent learned to use STL yet, and i dont plan to use them until i study them thoroughly and that's not gonna happen anytime soon. Do u...

I want to take integer inputs separated by spaces and terminated by newline character. suppose the user will be inserting integers this way

thanx for all that. I will be working on it and will let u know if i can pull it through.

>>I know it's weird, and yes thats just bcos it was the assignment. You said i could do this with running average, could u plz show me how?That's what i have been trying to do. Unfortunately, i dont...

i wanted to see the findaverage function independent. Most of my friends solved the problem using a global variable total and some did using static variables(none of which i liked). There are two...

I need to add a recursive function, called findaverage() into BST class that takes as input the root of the BST and returns the average of the entire integer items stored in that BST of integers.

I would like to see what kind of response u get.
I just have one thing to say OMG

>>This book will suck ur brain out.

Whaatttt? i thought Narue was a guy!!!http://daniweb.com/techtalkforums/techtalk-images/smilies/fiyellow/icon_lol.gif

Well she is a good programmer but an even better critic.

"Not unless the terminal stream supports seeking, doesn't discard previously read input, and you know exactly how many characters were read on the first pass."

hmmm, i did thought of these possibilities , but i think saving it into a file is much a easier process. So theres actually no way to read things back from console, i reckon.

I have a weird situation. Suppose a string will be entered as an input. using the getchar() function i count the number of characters the string contains until a new line character is encountered. So...

errr... sorry i forgot that sin() functions return value must be between -1 and 1 inclusive. What I should have said is that sin() takes a double as it's argument but takes it as if it is in radian...
