C++ :: How To Output Console Display To TXT File
Aug 8, 2014I am currently doing a complex number calculator ,and i wish to output my data to a txt.file . i tried fstream and it doesnt work. However the txt.file was created but no text was output.
Below is the program:
#include<iomanip>
#include<cmath>
#include<iostream>
#include<fstream>
using namespace std;
#define PI 3.14159265358979323

When impedance A & B are in series,the effective Impedance is " <<setprecision(4)<< z << " + j" <<setprecision(3)<< x<<endl;
else
cout << "
When impedance A & B are in series,the effective Impedance is " <<setprecision(4)<<z << " - j" <<setprecision(3)<< x*(-1)<<endl;

Visual C++ :: Receiving Windows Message In Console Application?
Oct 11, 2013I'm trying to write a program that passes Windows messages back and forth from another program that controls a laboratory instrument. I was able to write a program that successfully passes instructions, as evidenced by the instrument doing what I tell it. However, I am having trouble getting a return status from the instrument. The manual instructs the following:
// demo code, etc.
// send message to the instrument operating software here...
SendMessage(hwnd, WM_COPYDATA, tag, (LPARAM) &cd)
Either a completion message or return data is returned. Remote commands ReturnStatus, ReturnTiming, and ReturnData return data. In either case, data is received through an asynchronous windows message inside Win32 COPYDATASTRUCT type data packet.For example, a typical OnCopyData window callback is shown below, where the string data retrieved is finally stored into a Microsoft CString object. Note the use of variable replyTag, discussed above, which is used to isolate the correct windows message returned.
BOOL CUserDlg::OnCopyData(CWnd* pWnd, COPYDATASTRUCT* cd) {
….
if (cd->dwData == replyTag) {
/* String pointing to status */
CString retStatus = (char*) cd->lpData;
}
….
}
I can't tell if my problem is in generating the replyTag, getting the HWND to my own console window, or the actual receiving part of the code.
When setting the replyTag, the manual instructs: UINT replyTag = RegisterWindowMessage(“SOFTMaxProReplyMsg”);. However, I have to put an "L" in front of the string or I get a data type error (can't convert const char* to LPCWSTR).
When setting a HWND for myself, the manual instructs: HWND MyWnd = GetSafeHwnd().
That produces an error because GetSafeHwnd is a function of the Cwnd class, and I don't have a Cwnd. I have replaced it with HWND MyWnd = GetConsoleWindow();
When listening for the reply message, the manual instructs what I quoted above. However, I again don't have a Cwnd. I therefore simply used
if (cd.dwData == replyTag) {
CString retStatus = (char*) cd.lpData;
}
The above if statement always evaluates false, and the cd.lpdata contains the message that I had sent out instead of a reply message. How to get a reply using my console application. Here is the full code of my function:
Code:
#include "stdafx.h"
#include<iostream>
#include<vector>
#include<string>
#include<afxwin.h>
using namespace std;
void SendCommand(string command) {
// Get tags to identify the receiving and sending messages

C :: Take Integer Input For Temperature And Display Message For Different Ranges For Each Day Of Week
Apr 20, 2014I'm writing the program below to take an integer input for temperature and display a cheesy message for different ranges for each day of the week.
I tried using two if statements, the first to determine if the input is valid, and the else display that it was invalid and to try again.
The second set of if (if else) statements would evaluate a number input and display the cheesy message based on the value, or if it was out of range, to make you re input that days temperature.
I understand that the else statement is linked to the closest if statement, unless brackets are added to prevent this. I thought my brackets were correct, but I keep getting [Error]'else' without previous if'. The red lines are the if and else statement I'd like to be linked, and tried to do so by enclosing the 2nd if statement in brackets.
The assignment doesn't require the error checking, but if I don't use some form of it I believe it will just loop. Again I have to use the last 4 lines due to instructors rules, and have to use scanf and not strings or arrays.
This program will ask the user what the temperature will be for each day of the week. The integer input from the keyboard will be tested in a series of IF tests and a message will be printed depending on the temperature.

#include <stdio.h>
#define MAX 100

C/C++ :: Keeping List Of User Guesses And Output Message If Guess Is Duplicate
Apr 19, 2015The label "You already picked that" doesn't always appear. Sometimes it does, but only if a duplicate has been entered at least 3 times. I haven't been able to correct this. I am new to programming and array-based lists.

C++ :: Output To Console And Log File
Apr 4, 2013I have 18,000 lines of code that i would like to upgrade to include a log file. I want to replace the cout with a stream or something similar so that i can easily output to the console and to a log file at the same time with minimal change to 18,000 lines of code. I'm nearly there.
I used this post heavily as a reference; [URL] .... however it is highly incomplete and this is above my knowledge so I'm struggling somewhat.
I was able to get the bulk of it working with some guess work and modification to the code from that link.
For some reason i had to comment out "mstream(void);" and "~mstream(void);"
Also how to get :
mstream& operator<< (ostream& (*pfun)(ostream&)) {
pfun(coss);
pfun(cout);
return *this;
}
to work for endl as per the previous link. Not sure if i'm even putting it in the right place. Otherwise the code works fine for streaming to both locations and such. See the code below;

Nov 4, 2013is there a way to change output of console without clearing the screen? so making some kind of animation?
e.g.
I have used
Code:
cout << "Hello";
is there any way I can erase last "lo" and replace it by "p" so I will have "Help" without clearing the screen ? just changing the output like some text file?
I tried using something like this
Code:
#include <iostream>
using namespace std;
int main() {
cout << "abcd";
long pos = cout.tellp();
cout.seekp(pos-2);
cout.write("ef", 2);
cout.flush();
cin.get();
return 0;
}
but it doesnt work, there is still a "abcd"...

C :: Program Console Output Being Interrupted
Mar 6, 2015I am wrapping up a Linux/C programming assignment that requires several small programs for encrypting and decrypting text. There is a bash grading script which will be used to assess the performance of my programs. The script runs fine on my local machine and all of my tests pass, but when I run everything on my University's server via SSH, the script is not behaving the same. I am fairly certain the error exists somewhere in my C code, because no other students are having this issue. The 4 main programs consist of 2 daemons which wait for clients to connect via sockets, and the two clients. There is a daemon/client pair for handling encryption, and another for handling decryption.
And here is a screenshot of what happens with the same files on the remote server:As you can see, in the 4th and 5th tests (where the program's output should read), it's instead showing "ssIgnore this message". In later tests (not pictured) there is another message that reads "ddServer to client message". This text appears nowhere in my code or the grading script, so it must be server-side.
C++ :: Console Input And Output At The Same Time
Mar 4, 2014Alright, so to better myself with network logic I've decided to make a small net game.
I need to input commands to the console as well as output status updates at the same time. I'd prefer to write a gui interface for that, but I'd rather work with WinAPI as little as possible (I mean, look at the way it's designed...).
I'd like to do this with standard operations, limiting dependencies is a must for me.

Oct 11, 2013What does the order of console output from your program tell you about when the static object is initialized?
#include <iostream>
using namespace std;
//class

Firstclass(); //constructor
~Firstclass(); //destructor

Doesn't it allocate the class static variable to the heap, thus executing its algorithm then destroying it when the program ends - or. What exactly does it tell me? When the static variable is initialized, it takes place first before any of my other functions?
