This is a topic I have absolutely no clue about. I don't know where to start, or what to even do. If someone could please tell me the best language/software to start with it would be greatly appreciated. I've been told Fortran is a really good place to start, but is Fortran a language or...

Homework Statement Write a PC SPIM program that can (1) Prompt for a complete file name. [Note: Probably should be in the same directory as the program.] (2) Echo the input. (3) Test to see if a file by that name already exists. If it does, query the user to see if destruction of the old...

Homework Statement I'm starting my C++ project which requires me to call a file stream and output the data to four other output streams. Before I start, I want to know if I need to have a .dat file premade and saved somewhere so I can call it or do I just make that file in my code by using...

As a basic exercise in C++ functional programming, I wrote the following code: #include <iostream> #include <string> using namespace std; template <class T> void Wib (T& a,T& b) { T temp = a; a = b; b = temp; }; int main() { string A = "World!"; string B = "Hello, "; Wib <string>...

I'm taking a second-year chemical engineering course online with BYU (link: http://is.byu.edu/site/courses/description.cfm?title=CHEN-273-200#). It uses the Felder textbook (link: https://www.amazon.com/dp/047168757X/?tag=pfamazon01-20), which I reckon is popular for most ChE programs. What...

Homework Statement I need to create a program that will prompt for two integers, echo those integers, and then multiply them without using the multiplication operation and report the result. Homework Equations The following is what I have so far. The prompts and echoes work, however I do...

If a linear Program (P) has a feasible solution x_{o}, ( x_{o} not necessarily optimal),does it follow that there exists a feasible solution to the dual problem (D) as well? If yes, why? I know that the Strong Duality Theorem guarantees an optimal finite solution to the dual problem if the...

Hello everyone, Can anyone suggest me a suitable GUI programming language for windows (like Microsoft VB or anything else). The software should be free of cost. It also should not restrict me to publish my product as freeware/open source. (Additionally the software should be able to handle...

Hi, I have some basic background in Python and was planning to self-learn more programming. I was wondering if people here that have self-learnt programming in C/C++ and now using it for "real world" purposes (such as image analysis for BEC or data processing in particle physics) can share...

I decided to write my problem and attach as a separate document so that everything was included and would leave room here to discuss my problem. From what I understand from the equations is that for each value of u I calculate the value of the basis function for each basis function i. Then...

Is it worth it to take an extra 10 courses (and thus a whole extra year) of computer science courses in university on top of my 4 year electrical engineering degree? If I want to work in the electrical engineering field, how useful will the knowledge gained from these courses be? I'm planning to...

hello - Do you know which programming languages have probability distributions available to use such as the binomial distribution (as an example). I guess I would like to limit my questions if it's necessary to languages that are either free or cheap - no specialty math packages for...

This is a repost of an old thread, maybe some new members can give it a shot. This puzzle was included at the start of a casual IBM Fortran programming class for high school students back in 1969. (Yes, I'm that old). I don't know the origin of this puzzle. An extremely simple and old...

Hi, I've never programmed before but I recently downloaded the book "Programming from the Ground Up" and I plan to start studying it in 2012. I've heard that many programmers who learn to program in Assembly don't see a need to use anything else besides this programming language. Is this...

Homework Statement I'm trying to learn the Branch and Bound method. For that, I need to master the Dual Simplex Method (DSA). I have tried and tried and tried to google examples but can't find any. Does anyone know where I can find any? How do you know the LPP has become infeasible with...

Can anyone recommend me a textbook that teaches you how to write simple physics models? I would like to take everything I learned this year in physics 1 and create a program for it since I'm also a comp sci major. This is the best one I found so far but I'm not sure if it's exactly what I...

This semester while taking Linear Programming (Linear Optimization Models), we talked about using a linear program to separate two sets of points A and B. The general program is: Max d s.t. yA ≥ axA+b+d yB ≤ axB+b-d It can be expanded into finding a polynomial that passes between the...
