They should apply for: backspace, return, regular char input, vertical scrolling. There is only one buffer, and it is not allowed to side scroll past max col, instead it must scroll down, appending the line cur_y + 1.

View 6 Replies View RelatedI'm building a find and replace function for my text editor I'm building the function without support from the algorithm header.
The function is written like: doc.find_replace("Word_to_be_replaced", "The_word_that_is_replacing"); I find this very easy to understand replace this, with this.
find_replace will both have char * as their arguments.
The problem I'm having right now if I replace a bigger word for a smaller word how do I delete the extra characters from memory.
So if I replace "Goodbye" with "Hello" how do I delete the last two characters? So I don't print garbage code.
I am trying to make a text editor in C++ that uses Linked Lists as the main driving force. I need to make a program that can add a line of text at a certain point, delete a certain line of text, print the entire text, and quit and save the text to the original text file inputted from the shell script. My problems are with the cpp file, and the linked list files. My remove function is not what I need it to be I know that. I also know that there are some problems with my cpp file myEditor. My code is below.
#include <sstream>
#include "linkylist.h"
#include <iostream>
#include <fstream>
#include <string>
#include <cstdlib>
using namespace std;
int main(int argc, char *argv[]) {
//node* head = new node;

I'm supposed to make a basic text editor using a doubly linked list, I have pretty much written most of it but keep coming across several problems. In certain places,all marked in the code, I get the error "expected a declaration" ive looked online and nothing ive found works. And secondly I also get the error" declaration has no storage class or type specifier" but i havent been able to find anything that works either.
Code:
#include "stdafx.h"
#include <iostream>
#include <fstream>
#include <assert.h>
#include <string>

Any way to make a function that prints something. i wanted to make a function for
Code:
cout << " PAUSE MENU " << endl; cout << " 0. Resume Game " << endl;
cout << " 1. Commands " << endl;
cout << " 2. Controller Setup " << endl;
cout << " 3. Bottles of Beer " << endl;
cout << " 4. Quit " << endl;
cout << " What is your Choice - ";
cin >> userinput;
So i wouldn't have to retype it again in the loop, i would just call the function. but it seems whatever i try it doesn't display the text. i've tried making a function with no return time like this " Void Pausemenu(); " but that just goes blank.
Code:
#include <iostream>
using namespace std;
//This function displays different results based on the users input
int menu(int menuchoice);
int main()

I need a program that reads the number of lines of a file and then several (max of 20) lines of text from a .txt file so an example of the .txt file is: 2 This is the first string This is string number 2 So it first reads the 2 and then reads the two lines of text. It stores the text in an array of pointers. The code i have so far is:
#include<stdio.h>
#include<string.h>
#include<ctype.h>

I am trying to count the number of comparisons for each of the following sorting algorithms, Selection, Insertion, Bubble, Merge, and Quick sort. This is using an array of numbers that are sorted, reversed, and randomly arranged.
I currently increment the "number of comparison" variable before every conditional statement that compares two numbers and am getting the following results:
Number of Items in Array = 100
Selection: random = 5049; reverse = 5049; sorted = 5049;
Insertion: random = 2640; reverse = 5049; sorted = 99;
Bubble: random = 9207; reverse = 9900; sorted = 99;
Merge: random = 1221; revere = 988; sorted = 1028;
Quick: random = 690; revere = 587; sorted = 636;
Undirected graph G = {V, E} is given by the list next to the DS. Let u, v of V. Construction of two paths algorithm A1 (u, v) and A2 (u, v) such that no edge in common and have the shortest total length.

I would like for it to use a tile sheet from the user which they then can click on tiles from it and place it on the specified grid. Then export this as a binary file. Or perhaps it would be easier for the user to chose the grid size then have each grid space's number be able to be changed like 01,02,03 to represent an image. Then export this as a binary.

View 1 Replies View RelatedI am working on a script compiler that must output compiled script into binary file. Compiling etc is not a problem. The problem is detecting some specific cases. Nothing seems to work. If it works, then it breaks as soon as i modify the script.
Here is example "script1":
Code:
1VAR1 c1 = 44
2VAR2 c2 = 66
3beginscript
4if(c1=44)
5do_nothing
[Code] ....
Second example "script2", when there can be also some command between ENDIF and ENDIF. In this case: do_nothing command.
Code:
1VAR1 c1 = 44
2VAR2 c2 = 66
3beginscript
4if(c1=44)
5do_nothing
[Code] ....
The INDEXES before each line are not in actual script. They are just to point YOU to specific lines. Although the INDEXes are in compiled script!! This is very important. As you see there can be simple IF_ENDIF and nested (more complex) IF_ENDIF.
i.e IF_ENDIF inside another IF_ENDIF.
There are also IF_ELSE_ENDIF and some other ones, but im trying to make simple IF_ENDIF work first.
ENDIF is "SPECIAL" command, the IF, DO_NOTHING are "usual" commands.
"Usual" commands must always jump over(!) the ENDIF. ALWAYS!!
They must "ignore" them!
One strong RULE is like this for usual commands: always jump over any ENDIF, not matter what. If there is one, two or more ENDIF's in a row, then just jump over them to the closest NEXT usual block command. If there is some "usual" block command between multiple ENDIFs, then jump to this command and this command must therefore check whats next command right after it. And do the same: check if next command is ENDIF, if yes, jump over it, until "usual" block command is found.
This is the place im stuck. When i some time ago thinked about some ideas, i saw some patterns. One of them was that: Seems like if its nested IF_ENDIF, then every usual block command jumps out of it, i.e. right after the final ENDIF of this current nested IF_ENDIF.
But as soon as i added do_nothing between the two ENDIFs the so called "pattern" broke. In script2 above you see index 11 is do_nothing. Ok its in nested IF_ENDIF it should jump out to command index 17. But no, because there is do_nothing between index 13 and 16. If we jump out at index 11, the command 14 would never execute. This is a BIG NO. One idea i was thinking and trying was to use STL::FIND, STL::FIND_IF to find next "usual" command after specific index. But my code seems to crash sometimes and not work always.
Code:
bool NextNonENDIF(int i) {
return (i!=98);
}
int findNextBlockCmd(vector<int>&vec, int curidx)
[Code] ....
Here i pass him the vector that contains all the command TYPES in current script. Each command has its own TYPE or better called unique ID in which way compiler knows what is what. So in this case im trying to find a command thats NOT "ENDIF", in other words im trying to find next usual command after specific type of command. Lets just say the TYPE or unique ID of do_nothing is 555, im trying to find it.
How i should continue with this? What to use maybe stl::stack, some custom command indexing, some sort of labelling for usual commands in nested IF_ENDIFs or what?
In general, look script2, and i ask: There is index 11, this guy should look if there is any usual block command left for him before the final ENDIF at index 16. If there is, jump to it. If there is none, jump out of this nested IF_ENDIF to index 17.
Question: how to do it? What algorithms to use? I can use STL, BOOST, whatever. And i can use C++11.
I'm working with a game editor program, where the player can create their own maps. Right know I'm working with collisions, and since it's unpredictable where the player place the objects like trees, houses and cars...etc have I an idea with making a rectangle selection tool. Where the player can drag a collision box around the object, so the sprite stops when it hits the box. The problem is that I dont know how to make a tool like that. so my question is how do I create a tool like that (see picture under for more information)?
btw I'm using the SDL framework
here is a picture that illustrate the tool I want to create: [URL] ....
I'm working on a project which consists of several ocx loaded by one exe. The platform is WinCE. Now I'm on a process to create a new ocx. I do have a copy of those ocx projects in Win32 platform. These Win32 versions were only used to register ocx in local system and then put those on to application dialog by 'Insert ActiveX'.
Now the problem is those Win32 projects are so outdated, and unable to build. Getting too many linking errors to be solved.
I have build the new ocx and link that with exe manually by editing .rc file and all. But still no luck. New ocx is getting registered in WinCE device but failing to start application.
