Miért nem működik (megfelelően) ez a C++ program? (3) (forráskód lent)

// SquareDemo - demonstrate the use if a function

// which processes arguments

#include <cstdio>

#include <cstdlib>

#include <iostream>

using namespace std;

//square - returns the square of its argument

// doubleVar - the valuse to be squared

// returns - square of doubleVar

double square (double doubleVar)

{

return doubleVar * doubleVar ;

}

// sumSequence - accumlate the square of the number

// entered at the keyboard into a sequence

// until the user enter a negative number

double sumSequence(void)

{

// loop forever

double accumlator = 0.0;

for(;;)

{

// fetch another number

double dValue = 0;

cout << "Enter next number: ";

cin >> dValue;

// if it's negative...

if(dValue < 0);

{

// ... then exit from loop

break;

}

// ... otherwise calculate the square to the

double value = square(dValue);

// now add the square to the accumlator

//accumlator

accumlator = accumlator + value;

}

//return the accumlated value

return accumlator;

}

int main (int nNumberofArgs, char*)

{

cout << "This program sums multiple series/n"

<< "of numbers squared.Terminate each sequance/n"

<< "by entering a negative number. /n"

<< "Terminate the series by entering two/n"

<< endl ;

// Continue to accumulate numbers...

double accumulatedValue;

for(;;)

{

// sum a sequence of numbers entered from

// the keyboard

cout << "Enter the next sequence: " << endl;

if (accumulatedValue <= 0.0)

{

break;

}

// now output the accumulated result

cout << "/n The total of the values squared is "

<< accumulatedValue

<< endl ;

}

cout << "Thank you" << endl;

//wait until user is ready before terminating program

// to allow the user to see the program results

system("PAUSE");

return 0;

}

Ez egy "egyszerű" C++ program lenne, amit egy könyvből "másoltam" ki, de úgy tűnik, hogy valamit nagyon benéztem, viszont arra már nem tudok rájönni, hogy mit. Lett belőle egy jó kis infinite cout.

Előre is köszi minden helpet :)
