ofstream infile;
infile.open("Input.txt");
if(infile.fail()) {
cout << "Error Opening File in Input" << endl;
system("pause");
exit(1);
}
So I'm trying to see if it fails, but if i change "Input" name would the computer just create a new file name of it for example if i change "Input" to "asdf" the computer is just going to create "asdf" how do i fix it.
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();

Need Error handling for file opening and Reading that is used once, So far I have managed to do it for choice 1
Text file can be found in the attachment
why this is looping in an error message. I am inputting the entire file name when I run the program and it just keeps falling into my "if(!inputfile)" statement. Let me know if there is anything I'm just not seeing.

Recently I tried a project template from infragistics
Infragistics Windows Forms -ProjectManager
every time I open the design form it desply this message.
What should I do to resolve it.
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'm making a small MFC module that should generate a report (formatted using HTML) and then display it for a user on schedule at 8:30 AM every day. Pretty straightforward stuff.
I compose my report and then save it as a local HTML file in the CSIDL_APPDATA folder. I then use the following calls to display it using the default web browser (Internet Explorer in this case):
Code:
//Error checks are omitted for brevity
CoInitializeEx(NULL, COINIT_APARTMENTTHREADED | COINIT_DISABLE_OLE1DDE);
ShellExecute(NULL, NULL, strSaveFileTo, NULL, NULL, SW_SHOWNORMAL);
This module is run on schedule from the Task Scheduler. (The task is set up to run when a user is logged on, which is all the time for that PC. It is never turned off, put to sleep, etc. That computer has only one user that is never logged off either.)
This works perfectly fine when I test it by setting the task a minute or so in the future. But when the actual task is supposed to run at 8:30 AM, when the user wakes the screen all they see is a blank Internet Explorer page. (Note that if someone refreshes that page by hitting F5, only then my report is shown on the screen.)
So I started looking into it:
1) I checked that the file is properly saved (before calling ShellExecute) by reading it back and by comparing it with the original HTML markup that I saved earlier. It's all correct there.
2) I then checked the power saving options. That computer is set up to show screensaver after 5 minutes and to turn off screen after 25 minutes.
3) The web browser that causes this issue is IE version 11, with the latest updates installed. The operating system is Windows 7 Professional.
And why is IE showing a blank page only when computer is running unattended?
The code is supposed to display the total and averages of the data as well, but cuts off due to an error in the code.

Now, this only works for strings that are contained in the file wordlist. That being said, I would like this to repeat this search multiple times. Currently, the process is being repeated 7 times, but it only works on the first iteration. The code and sample input/output is below.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

4132dcba

The code is supposed to display the total and averages of the data as well, but cuts off due to an error in the code. The code should also:
1)Print checks for all employees, one per page, sorted by lastname. The first check number, 100, is to be read from a company data file (see requirement 4). The border of each check is important and should not be omitted.
2)Convert the net pay to a text string for each check printed.
3)Print a reference code on each check. The reference code is obtained by combining the first letter of the lastname with all the consonants remaining after removing all vowels (a,e,i,o,u).
4)Use the same employee data found in assignment 2. Use company data, obtained from a text file, for each check printed:
