int main()
{
int a=0, c, d, N, K;
bool stopBool = 0;

This is supposed to find take a number N and K and find all numbers between 0 and N that equal K and cout the number of pairs that fit it but it doesn't work.
Find all the prime numbers between a given pair of numbers. Numbers should be read in from an input file called "numbers.txt" and find all the prime numbers between them. Store the prime numbers in an array, then sort the array from greatest to least. Display the array before and after the sort.
I'm stuck on how to put the prime numbers into an array.
The input file has the numbers 1 & 100.
Here's what I have so far.
#include <iostream>
#include <fstream>
using namespace std;
int main() {
ifstream fin;
fin.open("numbers.txt");

I have an assigment to make program which deletes from sentence all words with character count which is equal to pair number , for example - [ I like C ] and the result of this program should be [I C] because the word like contains 4 characters which is pair and it should be removed.
So I started writing my program and I am stuck at this block of code -
#include <stdio.h>
#include <stdlib.h>
main () {
char text[100], blank[100];
int c=0,d=0,i,j;
gets(text);
[Code] ....
To explain what is happening - I go through all string and search for first ' ' space symbol and check its value. If it is pair then my program prints that it is not pair[because last character before space had not pair number of characters], but the hardest part comes in when i have two not pair words , because space takes one character and now when i check if i%2 == 1 the answer is false [0] for the second word .
how to make a programm in native c++ which print out all prime numbers less than or equal to given number????????

when i make
cout<<R1;

i get

In my program I am supposed to call isEqualTo with a user defined class type, and print out if my two numbers being compared are equal or not. I had to write two versions of this, one with just a template which works fine, but when I implemented the class, all the sudden my program just spews out true no matter if actually equal or not. Here is what I have so far:
#include "stdafx.h"
#include <iostream>
#include "UserClass.h"
using namespace std;
template<typename T>
bool isEqualTo(T value1, T value2){
if (value1 == value2)

I have tried to implement a much simplified version of boost::compressed_pair.What follows is a partially specialized EBO_pair<T1, T2> class template, written in C++11.The first type T1 is constrained to not be empty.The second type T2 may or may not be empty.
#pragma once
#include <memory>
#include <type_traits>

Edit: added non-member swap() function template.
Goal: To allocate some memory as a char*, read in some binary data, re-interpret it as a float* and then free the memory.
My code looks like:
void someFunction(float* &result) {
char * tmp = new char[1000];
//...Fill the char buffer here...
result = (float*)tmp; //Reinterpret binary data as floats
[Code] ....
Is the cast back to char* necessary on the red line (or could I have validly left it as float*)? Would it be different if I had written char * tmp = (char*)malloc(sizeof(char)*1000); on the blue line (and correspondingly used free (char*)floatData on the red line?

i have to make a program where a user inputs one number and i have to find the number of a certain amount of number in the program.
for example:
user input: 2349354787839
output: There are two sevens
i know it has the use of loops but i am having trouble finding a way to scan each individual digit in the input to find if it is a seven or not.
I have the random values down but when I try to assign randValue to another integer I get an error.I want to make an inner loop where I find 5 random number 50 times and print the average of those numbers.
I know I have the bare bones of the below, but without giving me a huge shove in the right direction can I have a poke? I have been programing for three months now. I have noticed when I do simple fun projects I learn more then what my professor assigned to me. The class is over but I want to keep building.C++ starts in one week...

if i have two integers, say number1 and number2, stored in arrays where each index is a digit of the number (i.e. if my numbers are 321 and 158, then number1 = {3,2,1} and number2 = {1,5,8}), can i find the remainder of number1/number2? assume number1 > number2.
