When you build and run a project in Xcode, the executable is placed in the build/Debug (or build/Release) folder relative to the project directory.

Perhaps your compiler decided to optimize the code by substituting the contents of the function for the function call as if the function were declared inline.

If you are assigning the return value of the new operator to arrays, it had better be a pointer.

Space in memory is reserved whether you use dynamic allocation or not. What that space holds is...

Just because it works with your compiler does not mean it will work with others. The initial values of an array are undefined in C++, which means they may be 0 or anything else.

To initialize an...

As this is C++, you can use STL functions to do the work for you:
#include <algorithm>
#include <iostream>

int main()
{
int array[] = { 2, 5, 8, 1, 4, 2 };
size_t array_size = 6;
...

Reverse psychology works well, it would seem. :P

I learned Java as my first programming language by reading Beginning Java by Ivor Horton. The book weights in at over 1000 pages. I found that an encyclopedic tutorial is an excellent way to learn...

Read the comments in the input function.

There is no operator for raising to powers in C++ similar to the ** operator in Python. You can do the multiplication or use the pow library function as suggested.

Is there a difference, in terms of performance, between the two loops below? (myvec is type std::vector<int>.)
std::vector<int>::const_iterator pos;
for (int i = 0; i < N; i++) {
pos =...

You can use the std::noskipws stream manipulator to alter the behavior of the stream. See here (http://www.cplusplus.com/reference/iostream/manipulators/noskipws.html).

That is a neat trick. Thanks.

I figured it out. I was calling the std::vector constructor with the arguments reversed (as well as providing an incorrect initial size). The solution:

Polynomial(int val = 0, int exp = 0) :...

coefs is initialized in the initializer list of the constructor:

Polynomial(int val = 0, int exp = 0) : coefs(0, exp), degree(exp)


Am I missing something? Thanks.

The default copy constructor should work for the Polynomial class below because it does not contain any dynamic data types. However, when I create a new Polynomial via the copy constructor, it...

I did some searching on this topic but couldn't find anything definitive.

Are basic types automatically initialized to 0 in C++ when allocated via new? For example, are all values of nums...

You are calling payroll::setvariables twice with 4 arguments, whereas the function definition specifies that it requires 7 arguments. In addition, you have not defined the function, only declared it.

How about this:

char *ns = malloc(l * sizeof(*ns));

Alternatively you can use STL functions:
#include <string>
#include <algorithm>
...
std::string::iterator end_pos = std::remove(str.begin(), str.end(), '\\');
str.erase(end_pos, str.end());

Ignore the pass-by-value/pass-by-reference discrepancies in the function declarations in my previous post.

@vijayan121: Thanks for the info, I have updated my code.

As a matter of style, is it better (in general) to write:

sarehu's code works for me.

Thanks, that is just what I was looking for.

What does this mean: template <typename> class Container? I can figure out what it does, but typename is not followed by a name, which I find...

I have a template function as follows:

template <typename T>
int my_func(T& arg)

T is expected to be of type map<T1, T2>. T1 is expected to be of a basic type (int, long, etc.) and T2 is...

If I declare a struct node, is the following legal in C++?

node nodes_array[vector.size()];


I know this is not legal in C. However, my C++ compiler does not complain. Is this only in recent...

Like ruggedrat said, a breadth first search will suffice. Starting at M, mark each reachable node as distance 1; from those nodes, mark each reachable node that has not already been visited as...

Ah, I'm an idiot. Some of the entries in Board::pieces were NULL. Thanks for pointing that out.

Thanks for the info.


The move function is empty: void Pawn::move(int rank, int file) { }. I should mention that Pawn (the type that is returned by board[0][0]) is a subclass of the pure...

Although my last question has not yet been answered, I have another. What is the difference between Piece* const* and Piece** const?

Here is my code for Board.h:

#ifndef BOARD_H
#define BOARD_H

#include <iostream>
#include "Piece.h"

static const int BOARD_DIM = 8;

@vijayan121: That would work, but I want to be able to modify the Piece corresponding to board[0][0].

Board b;
const Piece *p = b[0][0];

p.move(0,0); // not legal

Does this mean that I...

I am writing a chess game to familiarize myself with the C++ language. I have a Board class which contains a 2D array of pointers to Piece objects. I want to implement Board::operator[] such that...

An even better way to do this would be to create a Person class with the appropriate fields, and create a new class that implements Comparator for each desired sort order. See here...

float fah = console.nextFloat();

You can use a javax.swing.JFormattedTextField with a java.text.NumberFormat as the format. For example:
numberField = new JFormattedTextField(NumberFormat.getInstance());
