C :: Incrementing Number - Variable Count Stays On 1

Mar 3, 2013

I am forking 3 times in a loop like this but the variable "count" does not increment, it stays on '1' and therefore this is an infinite loop, and this simple thing dont make sense to me.

I have checked so that the pointer address is the correct one every loop.

Code:
void increase(int* x) {
*x += 1;
}
main() {
int pid, i, number = 0;

C/C++ :: Count Number Of Digits In Long Variable - While Loop

Aug 3, 2014

So I have been given and as part of the solution I need to count the number of digits in a long long variable. To do this I use a while loop, but it is behaving strangely. Here is the code.

#include <stdio.h>
#include <cs50.h>
#include <math.h>
int main (void) {
printf("What is the card number?");
long long card = GetLongLong();
if(card <= 0)

[Code] .....

When I execute the program it asked for the number, but then nothing happens. Of course, my first instinct was that the program was caught in an infinite loop somehow, but could not figure out how. I commented out the while loop and the program completed (albeit returning the incorrect value), so I was further convinced that there was an infinite loop that I was not seeing. I ran the program throug gdb. Strangely, the program did not loop infinitely, instead it got to line 16 [while(card1 > 0] and then just stopped, it was not executing the next line of code at all.

C++ :: Incrementing Values In Vector Based On Variable Input

Mar 24, 2014

I'm trying to increment the values in a vector, not the vector size, based on variable input. Basically I have a vector of size 10, and all of its values are initialized at zero. The program counts the frequency of numbers 0-9 in a four digit user input. This is what I have (I want it to work so badly but the compiler says that I'm using a pointer to a function used in arithmetic):

for (int i=0; i < num_slots; ++i) {
++guess_frequency[guess[i]];
}

I just want to know if you can increment values within a vector:

E.g.
change
0 0 0 0 0 0 0 0 0 0
to
1 0 0 0 2 0 0 1 0 0

C++ :: Search For A Number When Vector Is In Order - Count How Many Times That Number Appears

Feb 6, 2014

In this program what i'm doing is to search for a number when the vector is in order, and count how many times that number appears, the problem is that count how many times the number does not appear, but when its appear the program stays in an "standby mode" and the cursor does not move.

int buscarNumOrdenado (int x [MAX]) //MAX is the define {
int num,d, LimiteInferior, LimiteSuperior,mitad;
d=0;
LimiteInferior = 0;
LimiteSuperior = MAX-1;

C++ :: Random Number Generator - Count How Many Times Each Number Shows Up

Sep 26, 2012

I'm running a game online and designing a program to generate Enemy Stats. Basically, it's supposed to generate 25 numbers between 0 and 7(to represent 8 Attributes on a 25 Point Buy system) and count how many times each number shows up.

Here's what the code looks like:

Code:
#include <iostream>
#include <ctime>
#include <cstdlib>
using namespace std;
int Generate() {
int r= rand();
int s= r%7;
[Code] ....

And here's two outputs.

1: Code:

12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 12133089220 Stats[0]= 25 Stats[1]= 0 Stats[2]= 0 Stats[3]= 0 Stats[4]= 0 Stats[5]= 0 Stats[6]= 0 Stats[7]= 0 Stats[8]= 0 Disallowed system call: SYS_socketcall

2: Code:

14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 14787708434 Stats[0]= 0 Stats[1]= 0 Stats[2]= 0 Stats[3]= 0 Stats[4]= 25 Stats[5]= 0 Stats[6]= 0 Stats[7]= 0 Stats[8]= 0 Disallowed system call: SYS_socketcall

Note that the number does change, but only between runs.

C++ :: Method Passes Values To A Vector But It Stays Empty?

Dec 10, 2014

I have two classes, one class requests another class to populate a vector with some data using getAvailableStreams() method:

vector<AutoRefPtr<ManifestStream> > availableStreams;
std::cout << "now asking for streams." << std::endl;
manifest->getAvailableStreams(&availableStreams);
std::cout << "got so many streams: " << availableStreams.size() << std::endl;

The other class passes another pre-populated vector back:

virtual RESULT getAvailableStreams(std::vector< AutoRefPtr<ManifestStream> >* availableStreams) {
availableStreams = static_cast<std::vector< AutoRefPtr<ManifestStream> >* >(myStreams); //myStreams contains 1 stream

I'm also adding a stream here directly just for testing purposes:

ManifestStream stream2;
availableStreams->push_back(AutoRefPtr<ManifestStream>(&stream2));
std::cout << "calling getAvailableStreams. Giving so many streams: " << myStreams->size() << ", " <<
availableStreams->size() << std::endl;
return result_OK;
}

If I run the code, I can see the following logs:

Now asking for streams. Calling getAvailableStreams.
Giving so many streams: 2, 2
got so many streams: 0

Why am I getting 0 streams when I exist the method? I just had 2 streams in availableStreams while I was inside the method, where have they disappeared?

C++ :: Count Number Less Than Average Of All Number Combined

The following fuction from a class is supposed to count the number less then the average of all number combined. but it does not do that, now the fun part if you change it to count the number greater then the average it works great.

void IntegerArray::countBelowAverage() {
avrg=calcAverage(avg);
int count=0;
for(int x=0; x<100; x++) {

C Sharp :: How To Count Number Of Lines In XML

Feb 4, 2013

Below is the response XML my programmer is getting from business service -

<Data>
<Maintain>
  <AssetList>
     <AssetDetails>
          <AssetDescriptor> 
             <ns1:ParentProductCat category="ABC">ABC</ns1:ParentProductCat

[code].....

In above XMl if you check the ParentProductCat is prefixed with ns1:,ns2:,ns3:....

My XSLT code only checkes for the ParentProductCat but since it is prefixed with "ns*:" (* is integer) it fails to find it. So that in C# code replace function is used to replace ns*: a for loop is used for this and it goes until 1000

But now my response crossed the 1000 mark and this time the XML contains total 14500 lines.So I want to replace all ns:*

For this I want to count the number of lines present in the XML so that the for loop will run until that line number. how to do that?

C++ :: Generate 100 Random Integers Between 0 And 9 And Displays Count For Each Number

May 3, 2013

I've been currently stuck on a C++ problem. Here's the question:

Write a program that generates one hundred random integers between 0 and 9 and displays the count for each number. (Hint: Use rand()

% 10 to generate a random integer between 0 and 9. Use an array of ten integers, say counts, to store the counts for the number of O's, l 's, . .. , 9's.)

I think I'm pretty close, but I keep on getting "0" for the occurrences (or counts) of each random integer.

#include <iostream>
#include <cstdlib>
#include <ctime>
#include <conio.h>
#include <fstream>
using namespace std;
const int SIZE = 100;
