I am writing a spellchecker program and have some issues. First thing is that I need to make better use of the memory. My code iterates through a large dictionary file repeatedly. I know its better to read this into memory first then iterate through the block but I really …

Hello, everybody! I've been struggling on implementing the Binary Tree data structure with some standard functions in it. After reading information from many sources and some work on my own, I've came up to this: [url]http://pastebin.com/B6Gtjb61[/url] Problems occur in the main funciton. What I can't understand is why does the …

pls help me with this the user enters a number n.consider the sequence from 1 through n in ascending order.insert either '+' or'-' between each of the digits so that the resultant sum is zero. for eg: input=7 output= 1+2-3+4-5-6+7=0 1+2-3-4+5+6-7=0 1-2+3+4-5+6-7=0 1-2-3-4-5+6+7=0 however when i programmed it i only …

Hello, I would like to know how can I put a binary number such as 110 in a register in MIPS? Thanks,

I am having problems with my program to add and multiply two 4 bit binary numbers. The part in which I am currently having trouble is when I run the program the output for the addition function is not correct. Instead of displaying the correct answer it is just displaying …

There are many places on internet for great help regarding many things. Proper implementation of really fast routines for sorting data however is not common. I am not claiming these routines to be the fastest around, but their ease of implementation and use may make them welcome. As a thank …

I'm having trouble writing binary data out to a file. My end goal is to add a chunk to a PNG file; which has a format of: length (4 bytes), type (4 bytes), data (lots of bytes), crc32 (4 bytes). Collecting each of these pieces is not a problem, but …

Im doing my project on number conversion. I found the coding below. can anyone help me to explain the coding. why the coding have "count"? why the "count + 1"? what function of "count"?

Hi, Does anyone know a function that prints out binary tree in this form example : ................15 .........12.............17 .......10 14.........16 18 ? my Node class : [CODE] class Node { double Node_Data; Node Left_Child; Node Right_Child; Node Parent; }[/CODE]

Hello Daniweb! :) I am brand new to this site, and wish I didn't need the help but I do! So let's give it a go shall we? I have a program I have been working on for about two weeks now, and I feel like it should not be …

[CODE] #include<stdio.h> #include<conio.h> #include<stdlib.h> struct node {struct node * left; struct node * right; int info; }; typedef struct node node; node * root=NULL,*loc,*par,*save,*child; int item; void pre(node *); void in(node *); void post(node *); void find() { node * ptr; loc=root; par=NULL; if(root==NULL) { loc=NULL; par=NULL; return; } if(root->info==item) …

So my problem is writing a program that asks the user to input a number wich is stored with scanf then print the binary representation of that number in 32 bits, as in if the number is 1 i would need 31 0's and a 1. [CODE]#include <stdio.h> void dec_bin(long …

Everytime I run this program and enter a new record, it gets terminated on these statements: [CODE] stud.pcent=((stud.mhin+stud.meng+stud.mmat+stud.msci+stud.msst)*100)/(mm.hin+mm.eng+mm.sst+mm.sci+mm.mat); fwrite(&stud,recsize,1,file); [/CODE] The whole program is this. It is only partially complete.

Very trivial program which could be thought as conclusion from the Quiz posts (thanks Gribouillis for inspiration for format)

I have a program assignment in my C and Unix class that allows the user to enter two numbers in binary seperated by (*,+,-,or /). It then has to produce an answer and loop back to the beginning. It also has to have an option to exit. Can anyone help?

I think its more than a year that I ask my questions about programming in this forum.Looks like its the time that I help a little too. So I wanna put my best here.I hope it'll help some one. Still I'll appreciate any suggestion. Another point,It was my first time …

Lookup table is usually the fastest method to find function value, if number of values is small. Here we demonstrate the principle by using task of showing the value of byte as binary string or transforming binary string to byte binary value.

Hi there, I'm working on a map for a class assignment and running into trouble. I've tried looking around the web but couldn't find anything that helped. I know how insertion works on a basic level when returning a node pointer but think i'm missing some key ideas when using …

Hey guys, I'm working on a project to use Huffman trees to compress a text file into binary. For instance, based on the frequency of the characters in a string like "aardvark", a - 3 r - 2 d - 1 v - 1 k - 1, compression using a …

I was looking at a page called [URL="http://blog.sarathonline.com/2009/02/javascript-convert-strings-to-binary.html"]Javascript: Convert Strings to Binary (and representing in a nerdy way!)[/URL] where you can convert a [icode]String[/icode] into binary dots using Javascript and I loved that, but how I can do that? Since the code isn't for making that grid...
