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.

Apr 6, 2013I am trying to create a simple interface on console to allow to input some values to some variables. For ex:
int main() {
double a = 1.5;
double b = 2.5;
double c = 3.5;
string x;
[Code] ....
However, I want these three to display at the same time (now they display one by one), and in the console window I can move the cursor between input place of a, b and c with "arrow key" of keyboard.
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;
#include <iostream>
#include <fstream>
#include <string>
using namespace std;
class mstream {

C++ :: Change Output Of Console?
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.

View 7 Replies View RelatedC++ :: Static Variable Initialization - Console Output Of Program
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
class Firstclass {
private:
Firstclass(); //constructor
~Firstclass(); //destructor
[Code] ....
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?

C++ :: Output Unicode Number If Extract A Character Off A Console Or Out Of A File
Oct 31, 2014How do I output a Unicode number if I extract a character off a console or out of a file.
If I do the below, I use the Unicode number to show a character. The below shows me 25² .
char b = 'u00B2';
mystring = "25";
mystring.append(1,b);
How do you go back the other way? If I extract the 25 and the ² separately, how do I get the unicode number for ² ?
C++ :: Input File Directory From The Console?
Aug 19, 2014Convert this code into one where you can input the file directory from the console?
#define WIN32_LEAN_AND_MEAN // prevent windows.h from including "kitchen sink"
#include <windows.h>
#include <iostream>
#include <string>
using namespace std;
int main()
{LPCSTR Application = "C:Program FilesWindows Media Playerwmplayer.exe";
// Media file extension must be provided
// Paths are quoted

This code works but the directory can only be changed from the code not the console.

C++ :: Best Way To Show A Program Remotely And Also Provide Console Input?
Sep 27, 2013I want some people to see my C++ program, enter inputs (they can enter number 1, 2, 3, etc) as CIN, and then the program runs as it would if they were sitting in my place.
I have seen a few places which try to do this e.g.
[URL]
The problem is the CIN is not fully featured. For example in the first website you have to enter the input before you run the program. So that would not work for a program where CIN was being done all the time.
So I can get a domain, ask them to telnet into the Linux shell and compile and run my c++ Demo program. Is that the best way? Thats the worst case. I send them the .cpp file and they'll have to run and compile it on their own machine.
The best case is that they click on a link, get an online console and interact with it like they would with a real input/output c++ interface.how this can be done?
C++ :: Program Breaks If Copy Stuff With Multiple Lines Into Console - Clearing Input Buffer
Apr 16, 2014Using cin.sync() works great so far, but my program still breaks if you copy something with multiple lines into the console.
string test = "";
while(true) {
cin.sync();
getline(cin, test );
cout << endl << "test: " << test << endl;
}
However, if you were to copy this:
1
2
3
and paste it into the program, the output would be1
2
3
test: 1
test: 2
And if you press enter one more time:1
2
3
test: 1
test: 2
test: 3
The 3 finally pops out.

I would like to, when running cat, send in some data like "testing" to its stdin, and then catch the output of stdout, and put it into a character array variable.Currently the parent stalls till the child is done.I imagine the parent has to some how detect that the child executed 'cat', and then send in input to stdin?Then somehow detect that 'cat' is done executing, and read the output from stdout? I have looked around and found "dup2", but I don't understand how to send in and get data to the child from the parent, especially since the "file descriptors" is not pointing to any files in the first place..

C :: How To Arrange Input / Output Order
Sep 22, 2014for our school project, we have to make a program which involves three students and the prices each of them paid for the meals. The program has to calculate how much each of the students has to pay/receive to/from the others. Most of it, we got from our teacher. The error we are getting is that we have to 'take care of the input/output order'. So if you type in the names/numbers of the students in a different way, so for example if you type first number 1, then 0, then 2 and 0 and 1 have to pay money to number 2, number 0 has to be in front of 1. Our output is that number 1 is in front of number 0.
