C++ :: Difference Between F And Fn

Jan 26, 2013

#include <functional>
using namespace std;

template<typename...Args>
void on(function<void(Args...)> f) {
function<void(Args...)> fn; // this line causes error C2059: syntax error : '<fake-expression>'
}
int main() {
function<void()> f;
on(f);
}

What's the difference between 'f' and 'fn'?

C# :: Difference Between Char And Int

Feb 5, 2015

Creating a C# program to prompt the user to choose the correct answer from a list of answer choices of a question and if the answer is wrong then try to prompt the same question again with do while loop but it is not working as it suppose to be.

class Program
{
static void Main(string[] args {
char UserChoice = ' ';
do {
Console.WriteLine("What is the command keyword to exit a loop in C#?");
Console.WriteLine("a.quit");
Console.WriteLine("b.continue");

[Code] ....

But if i use int instead of char in this program and replace a, b, c and d with 1, 2, 3 and 4 then this program work fine. What is wrong in this code when using char

C++ :: Difference Between Cout And Cerr

Oct 30, 2013

Other than the theoretical difference between cout and cerr where the former puts values to the monitor and the latter puts values related to errors to the monitor, is there any real difference here? Why not use cout when you want to send anything to monitor? Why use cerr at all?

C++ :: Difference Between Iterator And Pointer

Jan 21, 2013

I just figured out that some std functions (for example: copy) need the resource and target objects have iterators to work. Otherwise, the compiler rejects. In case of two arrays, declared as:

double myA[100] = {};
array<double, 100> myB = {};

myA[0] is like a pointer, myB.begin() an iterator, if I do not make any mistake. So, what is exactly the difference between the pointer and the iterator here? They all give the access to elements.

If I need the target of copy to be an array like myA which cannot give an iterator, is there a way to make the command "copy" work for it?

int main () {
char name[256], title[256];

[Code] ....

which is preferable and can i pick characters one by one in string?

C++ :: Inverted Difference Triangle

Jun 21, 2013

Similar to Pascal’s triangle, the difference triangle has some interesting properties that find applications in various fields of the natural and applied sciences. In simple terms, a difference triangle is a set of integers arranged in an inverted triangle where each inverted triangle triad has its lower element equal to the difference (absolute value) of the two elements in the upper row. A difference triangle can be created from a sequence of integers forming the uppermost row by iteratively taking differences between consecutive terms to form the next row until a single-element row is created.

Example Consider the sequence 5, 8, 13, 21, 34, 55 from the Fibonacci series as the uppermost row of the difference triangle. The difference between successive elements form a new set: 3 (= 8 – 5), 5 (= 13 – 8), 8 (= 21 – 13), 13 (= 34 – 21), and 21 (= 55 – 34). The process can then be repeated until there is only one element left giving the following difference triangle:

5 8 13 21 34 55
3 5 8 13 21
2 3 5 8
1 2 3
1 1
0

Problem Write a program that forms a difference triangle using a given series of numbers as topmost row.

C/C++ :: Computing Bit Difference Between Two Arrays?

Jul 23, 2014

#include <stdio.h>
#include <stdlib.h>
int b_diff (int, int);

[Code].....

I am trying to take two arrays H[], and V[] and call each element to compute the bit difference(Hamming distance) and return that back to the main function to be used in calculating pixel_phase and pixel_smoothing. I'm getting an error that bit_diff cannot be used as a function and I've tried renaming it but nothing seems to work.

[ int b_diff (int a, int ] is how it should actually look.int b_diff (int a, int is how it should actually look).

C/C++ :: Difference Between Auto And Decltype In 0x

Jun 7, 2012

I'm having trouble with auto and decltype.

 void f(const vector<int>& a, vector<float>& b) {
        typedef decltype(a[0]*b[0]) Tmp;
        for (int i=0; i < b.size(); ++i) {
          auto p0 = new auto(a[i]*b[i]);
          auto p1 = new decltype(a[i]*b[i]);

[Code] ....  

The above code runs well in GCC4.7.

Could I use 'new auto(a[0]*b[0])' to allocate memory for the type of a[0]*b[0]?

And I can not distinguish the difference between decltype and auto in this case.

C++ :: Underlying Difference Between Reference And Pointer

Jul 12, 2014

I've read about the difference between the two, what one can do that the other can't syntactially, but I'm still very confused by the concept of references in C++. I'm trying to understand what is the difference in terms of undelying implementation.

Take, for example, the following code:

void foo(int *bar) {
++*bar;
}
int main(void) {
int n = 0;
foo(&n);
return 0;
} Translated into: Code: __Z3fooPi:

[Code] ....

Considering the above assembly code, and the memory that was used in both cases, I'm tempted to say that references was added to C++ to make the synax looks prettier... Where would I be wrong?

C# :: Difference When Starting A Program From Network?

Aug 17, 2012

The following code prevents windows from letting the monitor go into sleep mode when the program is active and wakes the monitor up after a scanner scans something.

Code:
protected override void WndProc(ref Message m) {
if (m.Msg == W32.Const.WM_SYSCOMMAND &&
(m.WParam.ToInt32() & 0xfff0) == W32.Const.SC_MONITORPOWER && m.LParam.ToInt32() != -1)
{
return;

[Code] ....

When the program is started normally it works fine. But when the program is started from a network share it goes to sleep anyway and the OnScan does not work anymore. Removing the Send Message line makes On Scan work again but then the monitor wont wake up on a scan of course.

What could be the problem here when started from the network?
