I'm saving the images in folder by using:
webClient.DownloadFile(href, sourcepath);
I don't want to give name as Current date and time..shown in given below code
string sub = @"Gadhada";
DirectoryInfo subFolder = dir1.CreateSubdirectory(sub);
Imagename = DateTime.Now.Year.ToString() + DateTime.Now.Month.ToString() +

I want to save my imagename as 1.jpg, 2.jpg, 3.jpg.
I was told to use a round function to round a number to give an integer number that is closer to the real value. (for example if the number is 114.67 I need to print an int value of 115 instead of 114)
I am not exactly sure how a round function works, but I am told to include math.h library. What I try doesn't seem to work.
All my code is good, except the functions: findMacLoc and findMinLoc .They don't give me the correct array location of the max/min number in the array.I know is something simple I need to tweak in those two functions.
#include <iostream>
#include <time.h>
using namespace std;
void printArray(int a [], int & size)
{
int i;
for (i = 0; i < size; i++)
cout << a[i] << " ";

i have only recently got into programming. i have this homework assignment that is frying my brains, the program needs to take a number from the user and give the 'reduced' sum. for example: if the user enters 888 then the sum should be: 6. it takes the number and adds its digits im just looking for a direction to where my problem is
#include "iostream.h"
int reduction (int number) {
return number/10+number%10;
}
int main() {
int number,loopcount;
cout<< "please enter a number"<<endl;
cin>>number;

I have two unassigned variables A,B . My program goes as follows
#include <iostream>
#include <string>
#include <cmath>
#include <stdlib.h>
using namespace std;
bool die (const string & msg);
[Code] ....
This a program that makes a calculator in which this is a small portion of it, all the exponent numbers work exceptfor anything ending in 5.
Examples go as follow 2^3=8, 3^2=9, 5^2=24
I want to why this happens, is it because they are unassigned variables?
I have to write a program to find the nth number of the Ulam numbers.
It's a bit complicated to explain what an Ulam number is but Wolfram explains it very well here: [URL]
I have to find the nth Ulam number but I don't know what I have to do to get that. My program gives me all the Ulam numbers from a range of 0 to n.
What I want the program to do is tell me that the 49th Ulam number is 243.

I am trying to write a program that checks whether the number is in sequence(as in if the numbers are in order it is a sequence). Ex: If the numbers are {1,2,3,6,7,8,9,10,11,13,15,17,20,21}, then, the underlined parts are a sequence. Now i want to find
1) the no of sequence in the array(in the above it is 3 )
2) the longest sequence (7to 11 which is 5).
The next code is right. I mean it works. It gives the sequence of fibonaci numbers ...
Code:
#include <iostream>
#include <iomanip>
using namespace std;
int fibo(int pos) {
if(!pos)return 0;
if(pos==1)return 1;
[Code] .....
But.... when I change the lines:
Code:
int r1=fibo(pos1);
int r2=fibo(pos2);
int r=r1+r2;
For the lines:
Code:
int r=fibo(pos1)+fibo(pos2);
It doesn't work right. Apparently it should work the same.
I have created an error message if the user inputs the wrong selection number
if (choices < 1 || choices > 5)
{
cout << "
Please Enter a number between 1-5
";
}
How would i create a error message if the user inputs letters/words instead of a number.
I am currently working on an assignment.
#include <iostream>

int main(int argc, char *argv[]) {
char letter;
int count = 0;
double ppl = 0;
double finalCost = ppl * (count - 1);

I am trying to create a word counter program that asks for the price per letter and then asks for the sentence they are writing. The app should then calculate the number of letters and give the total cost similar to:
You have 40 letters at $3.45 per letter, and your total is $138.00.
Everything compiles fine but when I run it the inputs don't work and it outputs:
You have -1 per letter, and your total cost is $-0.
I was trying to create a code to calculate the nth number in a Fibonacci sequence, when the nth number is entered interactively.

Server:Waiting for connection
Server:Receive connection from client

Server:Print 10 Fibonacci
Server:1 1 2 3 5 8 13 21 34 54
Client:1 1 2 3 5 8 13 21 34 54
if Client send value of 5, the output would be 1 1 2 3 5
When ever I enter a value higher than 10, my out put looks like this
How many numbers are in the Fibonacci Series? 20

0 0 0 0 34 21
13 8 5 3 2 1
1 0
Press any key to continue . . .
This is what I got when I entered the value 20.
As you can see, it will only display up to the 10 term of the Fibonacci sequence
I'm trying to get the output to look like this:

233 144 89 55 34 21
13 8 5 3 2 1
1 0

int main( ) {
cout << "How many numbers are in the Fibonacci Series? ";

I have to made a programme which will search for given number and it must work in O(log(n)). The problem is that this programme beside finding this number have to find how many times this given number is used in this sequence.
Sequence is from lowest to highest only one possibility to use binary search algorithm
For example when we have squence
-1 -2 3 3 3 3 4 5 6 7 7 8 9 9 9 9 10
The numbers we need to search are
1 , 3 , 7 , 9 , 11 , 12
The answer is
0 , 4 , 2 , 4 , 0 , 0
So we need to find the sum of used number in sequence.
I have written algorithm Code: int start = 0;
int end = sequencelenght - 1;
int mid = 0;
/// Binary serach
while (start<=end) {
int mid=(start+end)/2;
if (sequence[mid]==givennumber) {
[Code] .....
As u see i search for given numer with binary with O(log(n)) but when i have to sum the duplicates the only good way i see is using loop to right and left but this have got log(n) specification (because when sequence would be for example 7 7 7 7 7 7 7 7 7 and given number to search will be 7 this will be O(n) loop).
How would look the most optimal algorithm look for this exercise? I mean O(log(n)) the fastest algorithm....
I was doing a side project from my textbook about finding the mode, which is the number that occurs most often in a sequence of numbers. I racked my brain on this for an embarrassing amount of time and finally came up with this, which I think works but for some reason I still feel like I'm not done.
#include "stdafx.h"
#include <iostream>
using namespace std;
void mode(int *, int);
void main() {
const int NUMBERS = 15;
int list[NUMBERS] = {99,73,56,14,28,42,93,64,51,26,56,16,38,81,98};
mode(list,NUMBERS);
[Code] ....
Console Output:
Final Mode 56
Press any key to continue . . .
There it is, I would have commented more but I couldnt think of the right words to explain everything.

The code gives me seemingly logical integer values for size, width and height. But how would I find the max color value and so called "magic number" for this PPM image file?
Create a script that lets you rotate an image through some number of degrees(out of a maximum of 360 degrees). The script should let you specify that you want to spin the image continuously. It should let you adjust the spin speed dynamically.

Im trying to compare the image of a button to another image in Visual Studio like so...
//variables
Image active = Image.FromFile("C:\Users\Ethan\Desktop\StarWars Status\active.png");
Image stunned = Image.FromFile("C:\Users\Ethan\Desktop\StarWars Status\stunned.png");
[Code]...
btnStatusPlr1.Image SHOULD come back as True.Then I realized it might not be the same as setting the buttons image in the properties (Which is what i did to get the original image (the one being compared to))
I do have a feeling ive done something wrong here (Yes im a noob /> )
Variable active, is the same image as the buttons default (Well should be)

I'm trying to build a basic shell for Unix. This is the code I use to create a new process:
Code:
pid = fork();
if (pid == 0) {
setpgrp();
complexCommand(argv, isComplex);
[code] .....
Where complexCommand is a function that handles the command (uses execvp after generating the correct string out of argv). My problem is that after if while in the shell I use a program that needs to print to the screen and handle input, it doesn't work as expected. To test this, I built this small program:
Code:
#include <iostream>
#include <stdio.h>
#include <stdlib.h>
using namespace std;
int main() {
int x1, x2;
[code] ....
And when I use the shell I built to run it, the output is only "Enter 2 numbers" for one time. It doesn't print the result, or anything else. Is there anything I need to do in the parent process (my shell in this case) to give the child the output?
