I wrote this GCD function to find gcd of an array of numbers . Here is the code:
long long GCD(long long min,int loc,long long b[]) {
for (long long i=min;i>0;i--) {
bool p=0;
for (long long x=0;x<loc;x++) {
if (b[x]%i!=0)

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

Question: How to find a duplicate numbers and numbers found once in array.
View 7 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>

I have a question regarding finding similar 4 digit numbers in a pool of 120 numbers
Below is an linear single dimension array of 4 digits
There are 120, 4 digit numbers in total
My question is this - How can I code in C - a function that looks through all the 120, 4 digits to find similar numbers
Example - 2095 is similar or matches to - 0950, 5095, 5250, 5269 - i.e having 3 of the digits that are the same in the 4
The code must print out 2095 + all the matched numbers
If the Matched or Similar numbers are less then a certain number n - that number is discarded and the code should go onto the next number

View 8 Replies View Relatedi 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:

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'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!

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.
