Q)Write a program to find the sum between (2 numbers )
what's the problem here !
#include<stdio.h>
main()
{
int a,b,c;
int sum=0;
for(a=0;b>a<c;a++)
{
printf(" number1=");
[Code]...
int main()
{
int a=0, c, d, N, K;
bool stopBool = 0;
[Code]....
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.
user enter four number and the output will be the greatestt number among these
View 1 Replies View RelatedFind 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() {

fin.open("numbers.txt");

Its returning wrong answers. When i tried 6 14 it returns 6

View 8 Replies View RelatedI wrote some code for class to find prime numbers.The teacher says that I need to revise my code with the requirement below: use a bit array to store the prime number checking. The bit array will also be in the heap. Use the max value of an unsigned 32-bt integer (UINT_MAX) to be the maximum size of the prime number you want to check.
Code:
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <pthread.h>
#include <getopt.h>
#include <ctype.h>
#include <stdint.h>
//function to set all non-primes to 0
void *zero_multiples(void *threadid);

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...
Code:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define NUMBERS 5
int main(int argc, const char * argv[]) {
float randValue = 0.0;
int i;

I am trying to create a program that lists all prime numbers within a range of two number. Why the below program isn't working?

i did a code that determine if the number is prime or not, and i have to do a one that finding the prime numbers between two variables .
the first code:
#include<iostream>
using namespace std;
int main(){

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.

I made a program that is suppose to receive 20 numbers or less and find the average, then show all numbers entered but my average does not show. It shows as 0 and a line pops up after every number returned. I am stuck and dont know how to fix the logical errors.

how i solve this..?
View 1 Replies View RelatedI'm new to C++ and I'm trying to solve the question but there is just something wrong somewhere.

When I run my program it just gives me 'The smallest number is: 2682760' which isn't true obviously.

I'm working on a silent auction program that will scan a file and find the highest from each group of bids, then have a running total of money made throughout the auction. I'm pretty sure the rest of my code works, i'm just getting stuck on finding the largest number from the line in the file, saving it, then moving to the next auction.
input file text (first number is num of auctions, after that it's num of bids, then the bids):
5 4 100 500 250 300 1 700 3 300 150 175 2 920 680 8 20 10 15 25 50 30 19 23
Sample Output
Auction 1 sold for $500.00!
Auction 2 sold for $700.00!
Auction 3 sold for $300.00!
Auction 4 sold for $920.00!
Auction 5 sold for $50.00!
The silent auction raised $2470.00 for charity!

My question is how to write this code if the prototype of function is:
Code: void series(int *array, int n, int (*s)(int), int **begining, int *lenght);
1): write program to c++ to read three numbers from keyboard and find the average of the three numbers?
2): write program c++ to read two numbers from keyboard and swap between numbers like x=4; y=6; the result x=6; y=4;?
I think that int can do that job. but im not sure.
3): must be the result of positive example: (x+(-y)=z)?
with abs ?
4): values for each of : X= ;y= ;z= ;
I had to write a program to find all the primes between 1 and 100 using the sieve of Eratosthenes so I wrote this program :
#include <iostream>
#include <vector>
using namespace std;
// find all the primes number using Eratosthenes
int main() {
vector<bool> numbers(101);
[Code] .....
My problem is that if I try to modify the program to find all the primes between 1 and max (setting the size of the vector uqual to max) my program becomes slower and I would like to listen by other people some possible solution to don't use vector in this program, the author hasn't shown me yet how to delete a value from a vector so I just used this method to solve the problem.
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.
program:
Example input: 2 4 6 -1 7 3 -2 1
Output: 3 3 (longest series of even is 3, longest series of positive is 3)
Here is the code:
#include <stdio.h>
