I have to make a hardware project using a microcontroller, memory, screens, etc. Is it possible to make an independent PDF / documents reader, which is capable of running on battery power? Please note I don't want to use any technology which needs licensing. It must be all freeware readers, etc., and programing language can be assembly...
I have a listbox and I want to loop through each of the items to see if the string im looking for is inside. I know I could do .contains but that wouldnt look at substrings. The code im using looks like this: While tempInt > Listbox.items.count then if searchString.contains(listbox(tempInt)) then end if tempInt+=1 end while Everything...

So I am writing a program that deals with reading in and writing out to a file. I use the getline() function because some of the lines in the text file may contain multiple elements. I've never had a problem with getline until now. Here's what I got. The text file looks like this: John Smith // Client name 123...
I am supposed to be making a jeopardy game for my class. I was wondering it there is a template for it already out? Or do I have to make one myself, in which case, what would be the best approach to making this game in Silverlight? (My last resort is to make it in PowerPoint) ...
I'm having a great deal of difficulty trying to figure out the logic behind this problem. I have developed everything else, but I really could use some help, any sort of help, on the part I'm stuck on. Back story: *A group of actors waits in a circle. They "count off" by various amounts. The last few to audition are thought to have the...

I'm using Microsoft SQL Server 2008 Management Studio to create a relational schema by following an Entity-Relationship diagram. (included below; unrelated details removed) Until now, primary and foreign keys have been working as expected. But when I try to create a foreign key from the entity relationship takes onto the weak entity s...

Hi, i have been given some code to work out big o runtimes on them, could someone tell me if i am on the right track or not?? //program1 int i, count = 0, n = 20000; for(i = 0; i < n * n; i++) { count++; } Is that O(n^2)? //number2 int i, inner_count = 0, n = 2000000000; for(i = 0; i < n; i++) { inner_count++;...
hi! i have 3 tables A,B and C. table A has column employee_name,id table B is the main table and has columns id,os version. table c has the columns id,package id and p_version. I want to query the count of employee_name where the id of table a and c are matched with id of table b(which is the main table). I should also get the names...
I wrote a .sh file to compile and run a few programs for a homework assignment. I have a "for" loop in the script, but it won't work unless I use only integers: #!/bin/bash for (( i=10; i<=100000; i+=100)) do ./hw3_2_2 $i done The variable $i is an input for the program hw3_2_2, and I have non-integer values I'd like to use. How c...
I have hit a brick wall whilst attempting to create a two-class Java calculator. I have the code for an interface which works and displays ok but creating a separate class 'CalcEngine' to do the actual calculations has proven to be beyond me. I'd appreciate it if someone could kick start things for me and create a class calcEngine which...
I want to make my avl tree support adding duplicates but there is a problem with the default behavior of the binary search tree with duplicates that the rotation could make nodes with equal key be on the left and the right of the parent for example adding A,A,A will cause the tree to do a rotation to be something like that A / \...
New to C++, and for that matter OO programming. I have a class with fields like firstname, age, school etc. I need to be able to store other information like for instance, where they have travelled, and what year it was in. I cannot declare another class specifically to hold travelDestination and what year, so I think a struct might be ...
hi can anybody tell me the error in this? #include<stdio.h> int main() { char a[]="abcdefgh"; int i=0; int n=strlen(a); char *first; char *second; char *c; *first=a[0]; *second=a[7]; for(i=0;i<=n/2;i++) { *c=*first; *first=*second; *second=*c; first...
Generate 6 characters: the first character is randomly generated from the alphabets with odd ordering in the alphabet list (A, C, E, …, Y) the second character is randomly generated from the alphabets with even ordering in the alphabet list (B, D, F, …, Z) the third character is randomly generated from alphabet list (A to Z) each of the ...
I'm doing a grad-school software engineering project and I'm looking for the protocol that governs communications between ATMs and bank networks. I've been googling for quite a while now, and though I'm finding all sorts of interesting information about ATMs, I'm surprised to find that there seems to be no industry standard for high-lev...
I have a problem and can't solve it alone. My teacher gives me one logic task today, and i'm sure you can help me. How can I count the number of zeroes at the end of factorial(41). (on paper) I understand that it has nothing to do with programing, but I'm sure programers can help me. Thanks in advance. ...
Write a JAVA program that calculates the surface area of a cylinder, C= 2( π r2) + 2 π r h, where r is the radius and h is the height of the cylinder. Allow the user to enter in a radius and a height. Format the output to three decimal places. Use the constant PI and the method pow() from the Math class. This is what I've done so far bu...
