Why wont this C++ program show any Odd numbers!!!!!?

This works and shows the factors or tells if the number is a prime number but doesn't show ODD factors please help!! I need to turn this tomorrow:


#include %26lt;iostream%26gt;


using namespace std;


int prime(int num);


int main()


{


int num;


cout%26lt;%26lt;"Enter number: ";


cin%26gt;%26gt;num;


if(prime(num)==1)


cout%26lt;%26lt;"The number is prime";


else


{


cout%26lt;%26lt;"The number is not prime, factors are\n1\n";


if( num%2==0)


for(int j=2;j%26lt;num;j+=2)


{


if(num%j==0)


cout%26lt;%26lt;j%26lt;%26lt;endl;


}


for( int n=num;n%26lt;=num;n/=2)


{


if(num%n==0)


cout%26lt;%26lt;n%26lt;%26lt;endl;


}


for(int m=3;m%26lt;num;m+=3)


{


if(num%m==0)


cout%26lt;%26lt;m%26lt;%26lt;endl;


}


}


}


int prime(int num)


{


if(num %26lt;= 1)


{


return false;


}


if(num == 2)


{


return true;


}


if ( num%2 == 0)


{


return false;


}





for (int n=3;n*n %26lt;= num;n+=2)


{ if (num%n == 0)


return false;


}


return true;


}

I rewrote your program:


#include %26lt;iostream%26gt;


using namespace std;


int prime(int num);


int main()


{


int num;


cout%26lt;%26lt;"Enter number: ";


cin%26gt;%26gt;num;


if(prime(num)==1)


cout%26lt;%26lt;"The number is prime";


else


{


cout%26lt;%26lt;"The number is not prime, factors are\n1\n";


{


for(int j=2;j%26lt;num;j+=2)


{


if(num%j==0)


cout%26lt;%26lt;j%26lt;%26lt;endl;


if((num%(j-1)==0) %26amp;%26amp;(j%26gt;2))


{


cout%26lt;%26lt;(j-1)%26lt;%26lt;endl;


}


}


}


}





cin%26gt;%26gt;num;


return 0;


}





int prime(int num)


{


if(num %26lt;= 1)


{


return false;


}


if(num == 2)


{


return true;


}


if ( num%2 == 0)


{


return false;


}





for (int n=3;n*n %26lt;= num;n+=2)


{


if (num%n == 0)


return false;


}


return true;


}








Change this piece of code :


for( int n=num;n%26lt;=num;n/=2)


{


if(num%n==0)


cout%26lt;%26lt;n%26lt;%26lt;endl;


}





to this:





for( int n=1;n%26lt;=num;n+=2)


{


if(num%n==0)


cout%26lt;%26lt;n%26lt;%26lt;endl;


}
