C++ :: NCurses Outputting Vectors
May 19, 2013The following code works perfectly with "normal" C++
#include <iostream>
#include <vector>
int main() {
std::vector <std::string> hello {
[Code] ....
This prints "HELLO" on the screen. A function a bit more like NCurses is:
for (std::vector <std::string>::const_iterator it = hello.begin(); it != hello.end(); it++) {
std::string temp = *it;
std::cout << temp.c_str() << std::endl;
}
This still works with "normal" C++. Now, how do I get this working with NCurses? I tried
#include <curses.h>
#include <string>
#include <vector>
int main() {
initscr();
[Code] ....
But this just gives me an empty screen.

C++ :: Adding Content To Window Using Ncurses
Aug 12, 2013I'm makeing a card game with ncurses. I have all the card and player objects in order but i'm stuck trying to get the gui to work.
I'm using multiple windows for different players deck and pile. Now to the problem: I can get all the windows to show with borders in the console but i can't get any content printed in the windows and I rally can't see why!?
I have been reading the guide on [URL] but I don't get any further on the problem right now.
PS. the complete code incl. Makefile can be found at:

C++ :: Ncurses - Highlighting A Line Of Characters On Screen
Oct 25, 2013I am writing a program using ncurses that needs a function to highlight a line of characters on the screen. I started writing this function that took the x & y coordinates of a character on the screen and the length of characters after that to highlight. Whilst doing this I noticed that if I highlighted the last character in a row (maxX-1 in my example) it highlighted that character (as expected), and if I highlighted just the character before that (maxX-2) it also works. But if I do both, it highlights the whole row/line. Also, if there are characters in those spaces other than the 'space' character it works too, but for my program I need to be able to highlight empty spaces as well.
To highlight I am using inch() to get the character and addch() to print it because I am using some alternate characters that chgat() replaces with normal characters.
#include <ncurses.h>
int main(){
initscr();
start_color();
use_default_colors();
curs_set(0);
noecho();
int maxX=0, maxY=0;

C++ :: Make Terminal Screen Bigger In NCurses Program?
Jun 29, 2013I wanted to make the terminal screen bigger in my NCurses program. Let's say if the defaults are 25 LINES and 80 COLS, I want to set them to 40 LINES and 120 COLS.
I've tried resizing all windows, but that did not work, because the actual terminal (console) was not resized. Then I found functions resizeterm and newterm, but they did not work. As far as my understanding goes resizeterm only updates NCurses information with the current configuration, while the window itself is not actually modified.
NCurses man page wrote:The function resizeterm resizes the standard and current windows to the specified dimensions
If I haven't made myself clear ( I sometimes make a mess of things... ), another example would be that I want my program to be fullscreen when I start it. Is this possible? It should be, I found a fullscreen NCurses program once, but the code was too confusing for me to understand.
Having read about things like SIGWINCH, I assume you must define a method for resizing the terminal screen yourself, I don't know where to start?

View 4 Replies View RelatedC++ :: How To Start A Printer Queue
Nov 30, 2014Write a program to simulate a printer queue (priority queue or heap – Bentley article has code) where 3 printers are “fed” by this queue. Each print job has an unchanging priority and higher priority jobs go first (although once started, a job isn't stopped to let a higher one go). For each unit of time, there is a 26% probability that a job will be added to the queue and all jobs take 8 time units to complete. Print job priorities are between 5 and 100. The queue opens 20 time units prior to the start of printing for adding print “jobs”. A print “day” is 1000 time units. The output from your program is:
1) A list of jobs completed with their priorities for each printer
2) A list of jobs not completed (if any).

May 19, 2013How to write a simple script to convert F to C. That was easy enough once I read about how C treats the math of 5/9 being less then 1 thus converts to 0. Fixed that issue and the code works great.
I find it a useful tool and would like to, way outside of the scope of the homework mind you, figure out a way to get the script to restart if a [Yy] answer is provided at the end of the script. All other responses result in return(0).
I only have limited knowledge in BASH scripting. In BASH i would have just placed the int main(void) {foo} into a single function then created a simple if/then test after the function is called.
Reading up on functions in C, they do not work in the same way I would like to treat them from BASH. understandable this is not BASH.
then i started looking into do/while loops. On an other forum someone pointed out the possibility of using fgets as part of the challenge response. Now when I try to compile the code im getting an odd result. for some reason the compiler seems to think that my character string(or is it an array) is an integer...
Code:
/* 5. Write a program to convert a temperature in degrees Fahrenheit to degrees Celsius. *///##########################################################

[Code] ....
//above is were the homework ends, below is what im trying to do now.
/* Prompt for new input */
printf("
Would you like to enter a new temperature [Y]es or [N]o? ");
fgets( BUFFER, sizeof(BUFFER), stdin );
}
while ( sscanf( BUFFER, "%1s%*1s", ANS ) != 1 || strchr( "YyNn", *ANS ) == NULL );
return(0);
}
This results in the following error:
Code:
$ gcc -o hw_1_5.v2 hw_1_5.v2.c
hw_1_5.v2.c: In function "main":
hw_1_5.v2.c:52:

View 4 Replies View RelatedC# :: Switch To End Or Start Of Array Depending On Conditions?
Apr 1, 2015I have a seat allocation algorithm for an airplane 30 x 6 seats. The plane is 'split' front (1 - 15) and back (16 -30), right (A,B,C) and left (D,E,F). I am placing passengers in window seats front right centre (15A) first then back left centre (16F) followed by (15F) followed by (16A). This will continue for single passengers middle seats then aisle.
Another part of the algorithm is to ensure parties >2 or <=6 to sit together in an empty row, if not possible the party will be split as to not have a person in the party sitting alone firstly. i.e. 6 is 3 + 3 or 2 + 2 + 2 or 4 + 2 or 3 + 2 + 1 or 4 + 1 + 1 or 3 + 1 + 1 + 1 and so.
I have got it working for one person but seating two people is a bit more difficult. I am trying to get 15A,15B then 16E,16F then 16A,16B then 15E,15F then 16C 16D and 15C 15D.
This code only allocates passengers 15 A 15B then 15C 15D then 15E 15F
//seat allocation for two people
public bool[,] seatTwoPerson(bool[,] seatArray, int startCol, int endCol, int directionX, int startRow, int endRow, int directionY)
{ //loop through seatArray section determined by parameters
//for (int col = startCol; directionX < 0 ? col >= endCol : col < endCol; col += directionX)
