Hi. I'm learning how to program in assembly to PICs and I'm stuck quite a while in a problem trying to figure out how to read an input value. I've been googling a lot and it seems that my code it's fine but as I'm beginning to learn I would like to know if any of you guys could tell me if its...

Hi guys, straight to the point, how do you make your READ statement to be able to read both numbers and letters(words) or functions at the same time? okay, for example, i want the user to input a continuous function. what if the function is, let say, sin(x)? do i need to break the READ...

I'm well aware of all the Hangman codes that are out there given, but I feel that I will get a better understanding of this project if I did it myself with some help. My main problem is knowing how to compare one character of array from a string text file. The text file consist of a whole...

hi guys, so I'm in my third year at a UK university, studying Aerospace (Avionics mainly) Engineering. We've covered some programming in different modules. Some Matlab, some Java, some C. However, I'd like to start learning more thoroughly. Which languages are used the most in...

Hey there, (I apologize if this is in the wrong section - please move it if it is) I'm an EE undergrad, and I'm wondering how much embedded software/programming is involved in fields like control and signal processing. To be a bit more specific, by "embedded software," I'm referring to...

My question is simple. And that is: How to find out the programming language used in creating the softwares that we use on our different platforms/architectures/instruction sets? Is there any method to find it? Is it necessary that all the windows based software use C/C++ to create softwares...

I've done a very small amount of C++, but I don't want to spend the time I have to prepare on learning a language when it would have been more preferable to learn another (even though it seems you may use several language, and learning one helps to learn another.) But are there any language...

Dennis Ritchie died on the 8th, but I didn't find out until today. He created the C programming language. http://www.wired.com/wiredenterprise/2011/10/dennis-ritchie/"

Please explain what this C code will do : #include <stdio.h> /* count characters in input; 1st version */ main() { long nc; nc = 0; while (getchar() != EOF) ++nc; printf("%ld\n", nc); } 'The C Programming' Book says that this code counts characters but it doesn't do the same ...

I want to start learning Java programming,by myself. I got some PDF books. In the introduction, it talks about UML, but I find it complicated. I want to know whether it is a must to read the theory part, or I can just start on the practical part.

I was wondering which programming language I should learn for general purpose calculations and physics simulations. I already know a bit java.

Can anyone please explain what is EOF in C programming language. Is it a value (numeric, character) or something else ?? While reading the book "The C programming language", by Ritchie I came across this term. The code was : [FONT="Fixedsys"]#include <stdio.h> /* copy input to output...

Hi all, Greetings. This could be a basic question, and if it is, pardon me for my ignorance as I am a newbie to FORTRAN. I am trying to modify a FORTRAN code where I have added a subroutine (say SUB1) to calculate a variable, say (QX). What I did is to call this subroutine in another one...

I am taking Linear Programming and I haven't completed the course yet, but here is my question. I've notice that all these problems could have been solved just as easily with Lagrange multipliers. We got a bunch of linear inequality constraints and an obj function, we can use Lagrange...

Just like there's LaTeX for writing math papers and LaTeX editors to parse it, is there anything for writing papers in programming? Specifically a nice way to automatically format code.

It would be fantastic if someone could come up with a rough list of what you think the necessary skills are for a programming internship. Let's say in C#, for example. I read that companies want interns who are (in theory) very proficient at a language but want to apply their learned skills in...

I have been programming for quite awhile, but never extensively studied it. I took a AP Computer Science course that was taught in Java (Passed with a 5). I have known Java since 9th grade (4 years as of now). I learned Fortran 90 at Governors School for computational physics. I did a little C...

My professor wanted us to create a program that will automate the computations for our leveling practices, e.g. Computing height of the instrument when elevation and backsight is given etc. that may be tabulated. I believe excel would be the best bet for that. But he also included that we must...

This question has been bugging me. I have a math degree, and my computer knowledge is limited to VERY BASIC programming and being able to build my own PC, so I thought this would be a good place to ask. Note: This question has no "clean cut" forum to fit into. I read ALL the forum...
