Hello I'm writing a program that reads in data from a file to create an array of clients and stocks. I completed my client class and stock class. I'm stuck on my driver.  This is what I have it prints the text file but where would I include the array its part of the project? I would love any feedback.

analyze the problem. walkthrough the code. I would like to charge for this solution $10 to Renewal Computer Services, if I may post here (kids & teens free). when -50 is reached, doesn't blow past the maxvalue+1U and cause a cpu-hogging forever loop, it doesn't actually reach -50 equivalent (UINTMAX-49). #include <cstdint> #define ufordown0(var,maxvalue,step) for(uint64_t var=maxvalue; var>maxvalue; var-=step) /* Example: ufordown0(i,200U,50U) { } */

I got an assignment in which I need to create a physics calculator to solve the 'Motion' formulas, this is an screenshot of the formulas I need: [Motion formulas](https://imgur.com/a/sU8SfEk) The problem that I'm having is that I'm literally lost in how to implement them. I have found lots of tutorials but all of them want to solve for everything, I mean all of the letter of each equation and that's not what I want. I currently have this but I feel like I'm complicating my life with a lot of fuctions for something that is supposed to be simple. Right …

Machine learning is the science of getting computers to act without being explicitly programmed. machine learning has given us self-driving cars, practical speech recognition, effective web search, and a vastly improved understanding of the human genome. It is so pervasive today that you probably use it dozens of times a day without knowing it.

**Dear** I have the hyperspectral image --- how to preprocess data need time Traditional CNN cannot be applied to project directly --- it needs a lot of time to test (may be take 3 months) Need to do many experiments to get good result --- especially when compared to other existed methods (own contribution) May I know** how to simplify **my experimentation and research --- and I am using Spyder Python 3.7 with Winsdows 10 *Here I would like to apply the CNN and DNN for computing and later will compare that both of them which one is better or …

So the the longest time I had been struggling with popping and crackle when using HDMI audio on my GPU out to my TV. I've tried different cables, different graphics card drivers, new Windows installs, not using the nvidia HDMI audio drivers, uninstalling nvidia experience, even a new GPU, lots of things. I think the cause was a latency problem of some kind. I downloaded a latency checker program and indeed, when the audio was crackling there was a latency spike. I tried disabling various drivers, which helped, but never fully solved the problem. But then, after I did a …

I'm trying to write a function that will draw a right triangle that will ascend and then descend after the max height is reached. It is to be drawn using the asterisk symbol. I'm fairly new to recursion and that is the primary method I need to use to solve this problem. Any guidance or critique to my code would be appreciative. I can only edit the code that is marked TODO.  // File: main.cpp #include <iostream> #include <fstream> #include <iomanip> using namespace std; int recursiveCount = 0; void triangle(const char drawChar, const int maxHeight, const int currentHeight); int …

So, I have created a text file containing the following: 10001 General Electronics 500 20001 fACEBOOK 700 10002 Twitter 400 The records are stored in a struct containing an integer id, string company and integer number of shares variables. I want the user to enter a Id, say 20001, and the output should display the details of only that particular user and not of anyone else. Also, I want to change number of shares of user 20001 from 700 to 600.

Hello all. So, I'm in my final year of my B.Tech. in computer science programme and I have to do a project for my final year. The thing is I want the project to be unique/innovative. I brainstormed a few things: 1. An online music player that can store your local computer files on cloud. Sorts them according to album, artists, stars, favorites, etc. You can listen to your songs anywhere on any anydevice once the are synched. But this is already implemented by amazon as cloudplayer.com. Is there any extra feature or more innovative faeture that I can implement. …

Write a function (seat_type) that reads an input from the user that represents a seat class. The user should enter F: for a first class seat, C: for a business class seat, or Y: for an economy seat. The function should validate the user input to accept only F, C, or Y.

I am thinking of something that would require extreme use of algorithms, maybe a search engine or a distributed computing systems. Any other idea for heavily algorithim based project that would of course increase my marketability ? and by the way i have 2 instead of 1 year to complete the project if i start now.

Hello everyone, I am 23 years old and currently in my 2nd semester of my 4th year of college. Regular college students are typically done after this semester, but unfortunately I still have 43 credits to go due to starting out at a local community college and dealing with pre-requisites. I should be able to graduate by Summer 2013 even if I switch from CS to IT. Here is my dilemma. I am considering switching from Computer Science to Information Technology. I have started becoming less and less interested in programming. I am pretty sure I do not want a …

Hi all, I am at a lost and do not know where to start from. Here is what I have to do "Given the data below, you are to design an IA-32 assembly language program to sort array X by the number of binary 0's in each member and save the sorted array in Y.

Every day on his way home, little Billy passes by his great aunt Clara Mitchum's house. Generally he stops in for a chat with his aunt and sometimes he asks for some lollies. When he does, she generally gives him some, but then adds now don't be asking for any more for another N days where N is some positive integer. If N = 1 that means he can ask for some on the next day, but for example if it is April 6 and N = 4 then he must wait until April 10 or later before asking for …

I'm a computer science student at the University of Tennessee Knoxville and for my "Technical and Professional writing" course I have to interview someone in my field. Seeing as I know no computer scientist and my professors are too busy, would anybody in the wonderful Daniweb community be willing to lend me a short interview? Instant message, irc, chat room, doesn't really matter to me. Should take about 30 minutes ( I think) and we can do it at your convenience. I'd like to do it either today or tomorrow, but just let me know if this is at all …

so I recently wrote a function that sorted using the last value in a tuple. Obviously this couldn't be done simply say sorted(tuples, key=tuples[-1]) because that is not a "legal" call. However I did run across, while trying to figure out how to make things like this work, the utilization of lambda so the code became. [CODE]def sort_last(tuples): x=sorted(tuples, key=lambda tuples: tuples[-1]) return(x)[/CODE] The code runs correctly and, that's all well and good, but I don't understand why lambda tuples"or any given var for that matter":. makes this possible. Can someone explain this to me in a way I'll understand …
