C++ :: Alternate Keyword For Getch Function
Aug 18, 2014
I was trying to make a tic tac toe game where the user can play against the computer
It s in borland c++ and not in c++ 11 so i wanted to convert it into c++11. My program shows error since there is nothing called conio.h in c++11. Hence I want to know if there is any alternate keyword gor the function getch() so that i could ask the user to press [ENTER].
Code:
#include<process.h>
#include<stdlib.h>
#include<string.h>
#include<iostream.h>
#include<conio.h>
int usbox,i,j,nandu=0,result,cusb,cobox,r,d;
int playl=0;
char copybox[10];
[Code] ....

I'm trying to read a C code, but there are functions including CLASS word at the titles of functions. Is it a correct implementation?
For example: double CLASS getreal (int type)
What is the meaning of CLASS in titles of functions in C? I could not find such an usage in my C book?

I am asking for input for a char by using the _getch() function. The thing is that when a key is pressed multiple times it screws the program because it executes every single key that is entered.
I am asking for the user to enter a letter that will determine an action to be used in battle, like attack, magic, "use item", etc.
char option;
cout<<"Enter your choice for battle: ";
option=getch();
if(option=='a')
//Executes an attack
else if(option=='b')
//Opens magic menu
else if(option=='c')
//Opens item menu
Suppose the user enters a character, then the program executes an action by the enemy monster. This is where the problem arises, if the user entered multiple keys or if he enters input during the time the monster attacks, the next time it is the user's turn it will execute the first attack automatically because it keeps reading the input.
I want to know how to cut it off, so that it doesn't ruin the program like that.

How do reverse every alternate words in a string that I read into my program:
e.g. The mouse was caught in a clothes peg.
reversed (including the full stop)
The esoum was thguac in a clothes gep.
I could program it to reverse the whole sentence. But no clue how to reverse certain words such as every even word. Do I need a function and/or loop to solve this?
#include<iostream> // allow input and output
#include<string> // allow for larger entries of characters
using namespace std;
int main() {
string sentence, reversed_sentence;
[Code] ....

I am writing a program to hide files behind other files using Alternate Data Streams in Windows NTFS file systems.
The program is as follows:
Code:
#include <stdio.h>
#include <stdlib.h>
int main(void){
char hostfile[75], hiddenfile[75], hiddenFileName[15] ;
printf("Enter the name(with extension) and path of the file whose behind you want to hide another file: ");
scanf("%75s", hostfile);
[Code]...
The complier is showing error as "Extra Perimeter in call to system" but I am not getting where?

for starters i hope this question wasn't posted yet.i want to write a small program that askes the user what he wants to do , and then executes the comand in system . But for some reason it doesn't quit on the key word this is the code:
Code:
#include <stdio.h>
/*a simple interaction programme that schow the system options*/
#define systemt "x1b[32m" /*changes the color to green for system output*/
#define user "x1b[0m" /*changes the color to white for user input*/
int main() {
[Code]...
Is there something wrong white the code or does the system bock me from reusing the choise string. i'll inculde the original c file as well

have a look at the following code :
class Base
{
public:
virtual ~Base()
{
cout << "Calling ~Base()" << endl;
[Code]...
Now this program produces the following result:
Calling ~Derived()
Calling ~Base()
i was reading online and got stuck here. i am unable to understand why 'calling ~Base()' is been printed here? when we reached delete pbase; in int main() it goes to Base class first and finds that its destructor is virtual so it goes to Derive class and finds another destructor and executes it but why does it prints ~Base() in any case?

How to put virtual keyword in the function of the base class. Will the function still be over-written properly? What will happen if I
(1) call function from base class pointer
(2) call function from derived class pointer
(3) call function from derived class object
If the virtual keyword is present, the over-written version will be called in all cases, am I mistaken?

One thing make me consider:
FistClass F1 = new FistClass ();
FistClass F2 = F1;
second line why i dont need to firstly create instance for F2 and then make reference betwwen to classes like:
FistClass F1 = new FistClass ();
FistClass F2 = new FistClass ();
F2 = F1;

Is the bool keyword in C exactly like the boolean keyword in Java? why this code is getting an 'unknown type error' when I initiialze looping.
#include <stdio.h>
#include <stdlib.h>
int main()
[Code].....
If I am completely using the boolean concept wrong in C, should I just use break statements instead?

In C++ by FLTK, to define a circle we use some code like this:
Circle c(Point(x,y), r);
And we can using vector_ref put and save them in a vector, like:
Vector_ref<Circle> vc;
vc.push_back(new Circle(Point(x,y),r));
Ok, those were about Circle and no problem till now!
Triangle can be defined like this for using in codes:
Graph_lib::polyline poly;
poly.add(Point(x1,y1),r1);
poly.add(Point(x2,y2),r2);
poly.add(Point(x3,y3),r3);
and this is a vector to saving them:
Vector_ref<Graph_lib::Polygon> vp;
The problem is that how to save/put triangles/polylines into that vp vector using new keyword like the circle does?
My sig: Save Cobani.

I think there is no always need of keyword extern in order to declare variables globally. Is it right?
For example I can declare a variable globally in one file and use it in some other provided that I have included the last one file ( that has the declaration of the variable of course) and compile these files together :
gcc -c f1.c f2.c for example

I'm working on a program that reads in a .txt file and searches through the text for a keyword. If it gets a hit on the keyword, the line number where the keyword is located and the line that contains the keyword is printed out. What I have now doesn't catch every occurance of the keyword "a".

I am reading a file whick looks like following:
Code:
10 = NAND(1, 3)
11 = NAND(3, 6, 5)
15 = NAND(9, 6, 2, 8)
Problem: I have to find the word "NAND" and then find the numbers inside the brackets because they are the inputs to that NAND gate. I have written a code below but that code can detect the fixed number of inputs. I need a code which can detect any number of inputs (whether 2 inputs or more than two). But i don't understand how do i do that?
My code:
Code:
string input_str ("INPUT"), output_str ("OUTPUT"), nand_str("NAND");
while (getline( input_file, line ))
{
std::size_t guard_found = line.find(guard_str);

i need a function that will work for both dynamic and static implementations of a function to get the transverse of a matrix. so far, i have this
Code:
matrix transpose(matrix m)
{
int row, col;
row = m.com_dim;
col= m.row_dim;
}
[code]....
this works well with my static implementation, but when i try it in dynamic it gives me errors. the function has to be the same for both dynamic and static implementation

Ok so I am working on a game and I'm in the process of developing my Player class. Anyways, what I have is a keyboard function that is called in my main function to make a shape move.
void myKeyboardFunction(unsigned char key, int x, int y) {
switch ( key ) {
[Code].....
But when I try to call it, trying to copy my previous method,
glutKeyboardFunc(Player1.playerControls);
I get an error
error C3867: 'Player::playerControls': function call missing argument list; use '&Player::playerControls' to create a pointer to member
I get an error saying it can't convert parameters. I would just like to understand why the arguments become a problem when I make the function a member of my class, when the first method I used is so easy.

I searched the web for error: C3867... and the discussions where murky or obscure.
My code excerpt is:
#pragma once
#include <windows.h>
#include <stdlib.h>
#include <process.h>
void PutUpfrmIO(void *);
namespace WordParsor {
[Code] .....
I get the generic message:
error C3867: 'WordParsor::Form1::PutUpfrmIO': function call missing argument list; use '&WordParsor::Form1::PutUpfrmIO' to create a pointer to memberc:userskingc++wordparsorwordparsorForm1.h... and the suggestion fix generate another error.
One person suggested the gcroot<> object wrapper... but I do not know how to modify/declair the function or its argument type.

I have written a function that inserts and prints a binary function correctly.
For example a tree like this [URL] ..... would print like this
Code:
node: 10
node: 7
node: 6
node: 8
node: 9
[Code] ....
Here is my print function
Code:
void prt_tree(struct node *tree) {
if (tree == NULL) {
printf("Null Tree
");
return;
[Code] .....
Could I just make some adjustments to my function to reverse it? and if so, how?

I'm trying to pass 2 arrays into a void funtion, and return values to one function.
this is the the program I'm working with, after I'm done I have to split it into 3 files, a header, a main, and a separate cpp file for the functions to live in.
#include <iostream>
using namespace std;
void processArrary(int numberCount[], int Numbers[], int intnumberSize, int numberCountSize);
int main() {
int Scores[26] = {76, 89, 150, 135, 200, 76, 12, 100, 150, 28, 178, 189, 167, 200, 175, 150, 87, 99, 129, 149, 176, 200, 87, 35, 157, 189};
int numberCount[8] = { 0 };
[code]...
The goal of this program is to separate and count the groups of numbers then output the amount of numbers in each group. Near as I can tell, everthing should work, but I'm getting all zeros to be displayed in each group.

The function is supposed to return value from the file in my main, but I am getting empty value. I am trying to get better with pointer. Right now just teaching myself.
right now the only way for this code to show value is when in put the putchar(*ps) inside my readfile function. I would like to readfile to return value and print in the main function.
Code:
#include <stdio.h>
char *readfile(char filename[]);
int main(int argc, char *argv[] ) {
