5/1

so my parents thought it would be cool to go on vacation during the school week -_-

anyway ive been working on 2 different programs in that time


#include <iostream>
#include <cmath>

using namespace std;

int main ()
{
int num;
int x;
int root;
bool prime;

cout << "Please enter a number: ";
cin  >>  num;
cout  <<  endl;

root  =  pow(num, 0.5);

for  (x=2;  x <=  root;  x++)
{
if (num % x == 0)
{
cout << "number is not prime" << endl;
prime = false;
}
else
{
cout << "number is prime" << endl;
prime = true;
}
}


   
   
    system("PAUSE");
    return EXIT_SUCCESS;
}


for this one you are input a positive number and the output is supposed to tell you if the number you input is a prime number(if you cant tell this week is loops)


#include <cstdlib>
#include <iostream>
#include <iomanip>


using namespace std;



int main(int argc, char *argv[])
{
    int counter;
    int num;
    int zero = 0;
    int even = 0;
    int odd = 0;
    int N = 10;
    int sum = 0;
   
    cout << "please enter " << N << " integers, "
         << "posative, negative, or zeros."
         << endl;
       
    cout << "the numbers you entered are:" << endl;
   
    for (counter = 1; counter <=N; counter++)
    {
                 cin >> num;
                 cout << num << " ";
               
               
                 switch (num % 2)
    {
    case 0:
         even++;
         if (num == 0)
            zero++;
           while (num == even)
           {
                 sum = sum + num;
                 cin >> num;
                 }
         
         break;
         case 1:
         case -1:
              odd++;
         }
              }
       
         cout << endl;
         
         cout << "there are " << even << " evens, "
              << "which includes " << zero << " zeros. "
              << endl;
         cout << "the number of odd numbers is: " << odd
              << endl;
       

   

   

   
   
   
    system("PAUSE");
    return EXIT_SUCCESS;
}

this one was tough, you have to enter a set of numbers and then have it output the sum of the even numbers and odd numbers and how many zeros there are
