I am trying to teach mips to my self and wrote a fairly simple program and it isn't working and found out that the strings I declared in .data are somehow affecting one of my pointers. Here is the code: #Write a program that allows the user to enter 5 ints and store these ints in an array...

I'm learning C on my own time. I'm going at a pretty fast pace, but I'm highlighting most of the important things or at least, what I think is important so I can refer back to it later. I struggle with most of the back of the chapter exercises mainly because I'm going through it really fast and...

Hi there, As the title suggests, I am looking to start learning my first programming language. I am a mature student (24) who has recently returned to school to pursue physics. A friend of mine who does physics suggested that I learn Fortran (90/95) as my first language. I am looking online...

I have been solving some programming questions and all are some sort of puzzles? What are they trying to teach us with puzzles? What skills are they trying to develop by solving puzzles?

Hi everyone~ I think that I have used polling here where I shouldn't have done. Does anyone have any ideas? #include "p18f8722.h" #include "timers.h" void configure_PB2_interrupt (void); void enable_global_interrupts(void); unsigned char PB2_pressed (void); void isr...

Under what circumstances would you use ADCON1=0x0F? All I know at the moment is for using the pushbuttons and using the switches and then I saw a piece of code using the pushbuttons without this line in it and I was wondering whether I was wrong all of this time. I have tried googling and...

The universe keeps (emphatically) yowling at me to learn a progamming language. As part of my research in computational biophysics I'm attempting to learn python as rapidly as possible. But I'm trying to figure out which languages are most useful to learn, and which languages I should learn...

I want to start with assembly language programming after some years with C, cause I think it's a good way to learn how a computer actually works. But how I can compile assembly code under Mac OS X? I went to a library, and I had found out that many books are outdated, and no book covers...

Hi guys, I've started a programming internship about a month ago and i have some concerns and I'm hoping to hear some of your programming internship (or any internship for that matter) experiences. My biggest concern is that i feel that i am doing too much rummaging. I am always searching on...

Fortran has been around since the 1950s and obviously there is a large amount of Fortran code lying around. However, I'm curious if C or another programming language will someday supplant Fortran. Perhaps scientists will gravitate towards high-level math packages like Matlab and Maple, and...

Ok, so ill start this off with this, I don't know a whole lot about math. I do however have a question that I am pretty sure someone on these forums can help me out with. What I am looking for is an equation that I can later plug different numbers into. Lets say you have $1,000,000...

Homework Statement Alright, I actually solved this problem myself, it is just ugly and hilariously inelegant. I won't lose points since it is an introductory course, and it technically works, but I wondered what the "right way" to do this is. Here is what I had to do. Create an array where...

Hi everyone, It's that time again at my school-registration. I've been picking out my classes but I came across a rather annoying dilemma. My discrete math and data structures and program design classes conflict temporally. The discrete math class would count for my math minor, and the data...

Hello, So basically I am worried that once I begin learning math subjects beyond algebra I will struggle. I can program in C and BASIC and was wondering if that programmer knowledge will help me with the abstract thinking and problem solving part of it.

Hello, What programming languages are used in the majority of satellites? I was thinking it would be C,C++, and Ada because these languages are close to the processor. I'm sure ASM is also used too. Am I correct? I don't think any satellite uses Java but I could be wrong.

I'm an IT consultant and would like to ask for opinions. Do you think it is smarter to program algorithms or buy them from a library? Especially for complicated algorithms involving higher math functions. Some libraries charge a flat rate with unlimited downloads, they check their algorithms...

I'm updating some particle physics code from Pang's An Introduction to Computational Physics. It looks like he updated F77 code to F90, but kept a lot of iffy practices in like putting all of his functions, subroutines, and modules into one file without the use of a contains. What I'm aiming...

I am taking C++ this semester, and am not really good at it. It is my first programming class, and I kind of stink, though I am trying. I don't think I'm going to get a great grade, and it will bring down my average. I was thinking of dropping it, but then had a look at the class averages...most...

I started programming like 1-2 months ago - In most of the questions I actually try to tell the computer what I would actually do to solve the problem. I am just telling the computer what humans would do to solve that problem. Is that the right practice?
