I am doing my assignment that will calculate total tax amount per day and per week and finally sum those up.
One of the requirement is to filter out any number in the array that is less than 1000 to be assigned a value of zero instead of the stored value so as not to add it in the calculation. How to fulfill this requirement.
I am facing a problem which i could not obtain the total numbers which is greater than the average value. For example:
#include <iostream>
using namespace std;
int main (){
int size , count;
double no, max, min ,total, sum , average;
[Code] ....
In this case im able to compute the average of the numbers but when it comes to capture the total of numbers which is greater than the average value, how to compile the code , because the average number is only been compute once all the value capture by the input of user is sum up.
create a program that asks the user to input 10 integers of an array the program will add the numbers greater or equal to 10.

Create a program that will display all the composite numbers from 0 to 1000 and has a maximum column of 5 . A composite number is a positive integer that has at least one positive divisor other than one or itself. In other words a composite number is any positive integer greater than one that is not a prime number.
SAMPLE OUTPUT:
4 6 8 9 10
12 14 15 16 18
20 21 22 24 25
26 27 28 30 32
....and so on.
Sum up all the numbers between start and end. Lastly compare this sum to 1000.
--so i got the first part, but how to compare the sum to 1000.
I am new to programming in C++, and have got a project on this.
Write a C++ program that accepts three numbers from the user (All are integers):
Such as:
Enter the first mark: 3
Enter the second mark: 25
Enter the third mark: 23
The program should find and print the average of the odd numbers greater than 5 and less than 100.
I'm writing a program to display a histogram of 1000 Gaussian distributed numbers. I've generated the numbers using rand and now need to transform them. I have found the following formula to use
f(x) = exp(-x^2 / (2*sigma^2)) / sqrt(2*pi*sigma)
And I am unsure how to implement this into a function.
im trying to write a program that finds the max in an array and divedes it by two than oututs a modfied list with all the elements greater than the max/2.
I got the first part but just not sure how to find the elements greater than the max/2 and output them correctly into the modfied list.

Dynamic memory allocation in array in c programming. I am trying to make the user to choose the size of array they want to engage in the game.
However, i have remove the global variable which contribute the error to my code previously. Now I assigned all the arr individually but not using the global variable. However, i still not get the desired board i want. i still keep getting 9x9 array board.
And i also need limit the board size only from 4 to 9. And how do i do that.

How do I convert just the number from position 4 to 15 from this char array and convert to int and save to variable
char numbers[]="54155444546546545643246543241465432165456";
the real char got 1000 digits this is just example how do i convert chars from numbers[4] to numbers[15] and save them as one number ? in this case i will get int x = 5444546546545643 as u can see char numbers as a example above
I am looking for a way to create a virtual registry and force only certain programs to use this one? Or to create a virtual Registry but which i can shut down (this registry will be only used while i activate it)?
Or redirect all querys to another place in the registry I've seen similar issues. But there is no answer how to use the register selectively!
If I have a data file.dat like this, for example:
...
other information
...
physics:
4,5,6,7
...
line:
(4,2), (2,4)
line:
(1,2), (2,3)
...
...
I want to design a class and corresponding code so that every time when it reads "line:" for the file.dat , it will push_back a new line into the line_t vector, and each time when it encounter physics it will put the values to physics, How can I implement this?
every data in file.dat is useful, they need to be read into different class type. How can I implement this?
class line_t {
public:
vector<point_t> P(2, point_t());

I have a pile of data, which i need to access frequently and fast. One entry consists of two unsigned ints, let`s call them source and destination.
One source can have several destinations, but this rarely ever happens. Several sources can have the same destination - this happens more frequently, but still scarcely.
Once the data is set up, it rarely ever changes - yet it should be possible to add or remove entries.
I now need to find all sources for a given destination, or all destinations for a given source.
The question: which stl container to choose?
I have tried a multimap, using the source as key. This works good for finding all d for a given s, but is inefficient in the other direction.
Do you think it would be more efficient to have two multimaps, sorted respectively by source and destination?

vec.push_back(i);
random_shuffle(vec.begin(), vec.end());
nth_element(vec.begin(), vec.begin()+7, vec.end());

Write the function itob(n,s,b) that converts the integer n into a base b character representation in the string s . In particular, itob(n,s,16) formats n as a hexadecimal integer in s .
Note that it says the result is formatted into a hexadecimal integer in the string s. Here is the example provided:
Code:
void itob(int n, char s[], int b) {
static char digits[] = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ";

above is my program, I have received an assignment which the lecturer request us to find a series of k numbers then
-display the average
-display the total of numbers greater than the average
our lecturer request us do in 2 version, one is by using array, one is without using array, I have facing the coding problem when doing the VERSION WITHOUT USING ANY ARRAY to get the display the total numbers greater than the average, is there possible to get it?? because there are only one variable keep on looping, but the average will only get after get all the user input....?
I was wondering if there was some sort of C++ equivalent for the IDL FIX function. For example, say I want to find all the elements of FLOAT ARRAY1[] that are greater than NUM1 and convert them to INT ARRAY2[].
The problem I have with writing this code myself is not knowing how many elements are going to be greater than NUM1, so I don't know how to initialize ARRAY2[?].

I am working on a program in C# that should make a user choose a specific path for the program to work.
The path they are choosing is a path for a game and from that selected path I use coding to load pictures from to the program.
Anyhow
I am able to make the user choose a path and save the selected path in a xml file.
But the user can select ANY path.
How could I do to make the user choose a specific path that I want them to choose?
I've just started using the CImg library and when I try to load a picture with this code:
CImg<unsigned char> image("example.bmp");
It works perfectly. But when I try to type in the image file name using the console it gives me errors. For example, if I try this:
std::string input_file;
std::cin >> input_file;
CImg<unsigned char> image(input_file);
It doesn't work. The way I see it, I should be able type "example.bmp" into input_file and use it but it doesn't work, and gives me the error:
"error: no matching function for call to 'cimg_library::CImg<unsigned char>::CImg(std::string&)"
I have included iostream and string.h.
I've implemented a records system for a college assignment and everything works as intended. However upon increasing the amount of records to store in my array above 10, the program crashes upon adding a new employee and I can't work out why...

#include <string.h>
#define esize 10 /* Change max-records */

I've read that we can write a program that displays a menu of commands for the user to choose from.We can write some functions that implement these commands, then store pointers to the functions in the array :
Code:
void ( *file_cmd[])(void) = { new_cmd , open_cmd }; // 2 cmd's for simplicity
We can get a similar effect with a switch statement but using an array of function pointers gives us more flexibility since the elements of the array can be changed as the programm is running.
I decided to write an example about this in order to understand better the context, I am facing some problems though :
Code:
#include<stdio.h>
#include<stdlib.h>
typedef void (*p_foo) (int);
void foo(int x);
void foo2(int y);
