I am writing to write a program and performs the following tasks
- Reading a file (txt file contains some temperature values) - Display the temperature values (contents of the file) - Calculating the average of the temperature values in the file. - finds the maximum and minim value of temperature in the file.
The program is user interactive and waits for the user input and process according to his input (choice)
I have managed to complete the program and covered all the expect except the error handling for file opening and reading, although I have managed to do it for the part one part (i.e for the choice == 1)
I can repeat it for the other choices (i.e for 2, 3 ) but I do not want to repeat the code and do it in a different function or do it once for all. While making an attempt I can not handle the rest of the program and all the program turns into a mess.
#include <iostream> #include <fstream> #include <iomanip> int menu(); int myChoice(char); char inputValidating();
[Code] .....
Need Error handling for file opening and Reading that is used once, So far I have managed to do it for choice 1
I'm attempting to write a method that opens a file from Excel, finds a value within the spreadsheet and returns the value from another column along that row.
So I know I want to pass in the filename and the item I'm initially searching for, plus also a column identifier and that way I can locate so something like this:
public static int GetParameter(string filename, string parameter, string channel)
I've attached a snip of the spreadsheet so you can see what I'm lokoing at. I want to open the spreadsheet, find the parameter I've specified, move along the column to find the channel I've specified and finally read and return the value.
The bit that's troubling me is I have no idea how to work with excel in c#. I've done a few searches and I believe I need to add thiese references
using DocumentFormat.OpenXml.Spreadsheet; using DocumentFormat.OpenXml.Office2010.Excel; using DocumentFormat.OpenXml.Office.Excel; using Excel = Microsoft.Office.Interop.Excel; using Excel;
I have added those usings and also made reference to them in my project. I was also looking at this as well but it just confuses me in how I add my parameters and modify the code to suit:
using System; using System.Windows.Forms; using Excel = Microsoft.Office.Interop.Excel; namespace WindowsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent();
I'm in a CIS 143 class which is Introduction to Programming using C++. We've been assigned a lab with little to no detail on how to do the things listed.
The purpose of this lab is to practice the file input and output concepts. For this lab you may assume that the input files exist and contain appropriate data inside of them.
Four separate text files* which contain the following lines, different for each file.
(*: This isn't on the lab, but don't worry about what the name, age, id, and major are. those can be random and I can just change them what they need to be)
Name Age Student ID Number Major
Your program should ask the user which of the four input files they would like to open, and then read the contents from the file. Once the contents have been read in, it should output to both the screen and a file named "output.txt" the four values were read in, arranged as follows:
"Hello <name>! You are a <age> years old <major> student, and your ID number is <ID number>"
Now I am by no means saying "Do it for me". I just need to know how to have a user type file1, file2, file3, or file4, and then have the program open that file, then have the output.txt file arrange the wording into the sentence above.
This is what I have so far and I don't think it is anywhere near correct:
#include <iostream> #include <fstream> #include <string> using namespace std; int main() { ifstream inFile; string file1; string file2;
I want to open a command prompt from a console application in a separate window and write some lines of text in the new command prompt.
In the Below code it is not opening the new cmd and not writing the text...
Here is the code: public static int Main(string[] args) { int retValue = 0; try { ProcessStartInfo MyProcess = new ProcessStartInfo(); MyProcess.FileName = "cmd.exe";
extracting records from a text file based on the user input of a specific date. Below is a image of the Text file with Dates and records that follow. a code to extract records from file based on the day the user enters with month and year not necessary here.so it is based on the day the user enters, which the code will extract the records and if day is not found then "DATE NOT FOUND"
I'm writing a code which has to read a text from a file. In this text, there are some symbol and numbers (ex, This is $19 of....). Those symbols and numbers should be replaced with the words from the other file. i.e.
transformed file
This is just an $19 of what the $5 should obtain.
And $19 should be replaced from association file
19 example 5 program
The result:
This is just example of what the program should obtain. I'd like to save the first file content into an array of strings and the same for the text of second file.
I got an assignment to do...and in that i need to get the inputs from a .txt file....and im not getting how to read the data i want and skip the rest thrash.
The program runs fine but i just want it to read the inputs from a text file rather than user manually entering it! what changes should i make in the codes..
I would like to program a simple finite element solver in c++ (I'm a relatively new programmer by the way). This is the issue, I have a text file with all the information of the model arranged in matrices; an input file would look something like this:
I am trying to read lines from a .txt file like this:
// "file.txt" This is the first line. This is the second line.
To do this, I tried using the following code:
int main() { std::ifstream data; data.open("file.txt");
[Code] ....
The output I want is:
This is the first line. This is the second line.
However, all I am getting is:
This is the first line.
I can't quite see why this isn't working. I am decently familiar with file streams in C++, so I thought I would know what I was doing, but apparently not.
I need to open a text file game_scores.txt and i can not figure out a way to.
#include <iostream> #include <string> #include <fstream> using namespace std; int main() {
[Code] ....
the code is used to read the text and take the first 4 pieces of info but i do not know how to do it. i have already created the text file and moved it into the source. i am using visual studios 2012. In 2010 the text file would show a relative path, it doesn't in 2012
Reading in a maze into a 2D array. The first two reads will give me the dimension of the maze(ex. m x n maze). So in order to create the 2D array i need the first two reads. Then after it is created it will read the rest of the data which are 1s and 0s. I have to create a program that will solve the maze but i cant test my movement code if i cant read in the data first. the entire program compiles but to test if i read the file i have a function to print it. But it says "There are: 0 rows and 0 columns " so it didn't read anything since rCount and cCount are initialized to 0. and basically the maze has nothing in it.
read some information from a text file. The program I'm working on is like a simple betting program.
What I need to read are:
match_code - team1 - team2 - odd1 - odd0 - odd2 139 Atletico Madrid - Real Madrid 2.853.40 2.35
But the spaces between datas are not known. We only know that both team names may contain more than one word and there is one space, exactly one dash and one more space (" – ") between team names.
Also match_code is an int and odds are double values.
I am working on my final project for my intro to c++. Its a simple program where you buy a car, choose parts for it, see the price of it in total, buying option, and to view past records.
So my problem lies with displaying the records. For some reason(doesn't many how many records there are) the very last record displays again without the "Model" part, but displays the rest of them fine. In other words, there are 2 problems, the last record is displayed twice, 2nd that added record displayed is missing the "model"(this problem doesn't matter really if you can solve the first problem, but would still like to know why it does that).
I tried debugging it and I believe the problem lies with the --------while(fName.good()). It just decides to repeat it again even though in the text file, it does not have that extra record.
I am trying to read numbers stored in a txt file to populate an integer array. The problem is that the numbers read from a file have to be treated as strings and then I am not able to put them in an integer array.
I tried the stoi function to convert the string in 'box' into an integer but I am getting an error.
Code: #include <iostream> #include <stdlib.h> #include <fstream> #include <string> using namespace std; int main() { int amount=10; int k[amount];
I have to take a text file with 62 8 25 7 90 82 22 46 15 54 in it. The array has to read from the file. I cannot figure out how to do it. This is what I have.
I wanted to improve the game from my last thread. I want to read and store a question in this format: Code: Who invented the BALLPOINT PEN?
A - Biro Brothers B - Waterman Brothers C - Bicc Brothers D - Write Bothers
But when I use fgets() to read the string, it reads all the ' ' literally instead of outputting a real newline. Like if it read the above question, I want it to print something like this:
Code: Who invented the BALLPOINT PEN?
A - Biro Brothers B - Waterman Brothers C - Bicc Brothers D - Write Bothers
