while loop weirdness (does not accept compound statements?)

well i have finally solved my problem! woooohoooo!

now here is my question try to uncomment that while loop with the two statments and try using it... why does it not work when it is compund statement? any way to fix this?

Code:

---

#include <iostream.h>

int main()

{
        int number1;
        int number2;
        int stonum;
        int count=0;
        int num1;
        int num2;
       
        cout<<"Enter one single-digit number: ";
        cin>>number1;
        cout<<"Enter one single-digit number: ";
        cin>>number2;
       
        cout<<endl;
        cout<<number1<<" "<<number2;
               
        //while ((number1!=num1)&&(number2!=num2))
        while(number2!=num2)
        {
                if (count<1)
                {
                        num1=number1;
                        num2=number2;
                }
               
                count++;
                stonum=((num1+num2)%10);
                cout<<" "<<stonum;
               
                num1=num2;
                num2=stonum;
       
               
        }
        cout<<endl;
       
        return (0);
}

You have to place while loops within brackets { }

Do you get a syntax error or is something not working right?

no try it for yourself... it compiles fine but the while loop with the two statements will not analyse the second part of the statement for truth why does it do this?

You're telling me this doesn't work?

Code:

---

#include <iostream.h>

int main()

{
        int number1;
        int number2;
        int stonum;
        int count=0;
        int num1;
        int num2;
       
        cout<<"Enter one single-digit number: ";
        cin>>number1;
        cout<<"Enter one single-digit number: ";
        cin>>number2;
       
        cout<<endl;
        cout<<number1<<" "<<number2;
               
        while ((number1!=num1)&&(number2!=num2))
        {
                if (count<1)
                {
                        num1=number1;
                        num2=number2;
                }
               
                count++;
                stonum=((num1+num2)%10);
                cout<<" "<<stonum;
               
                num1=num2;
                num2=stonum;
       
               
        }
        cout<<endl;
       
        return (0);
}

I don't feel like opening a compiler right now but it looks fine to me.

yes the while loop will only check for this (number1!=num1) and when it is true it will end... the second part of the statement seems to have no effect on it... im not sure why...

int main()

{
int number1;
int number2;
int stonum;
int count=0;
int num1;
int num2;

cout<<"Enter one single-digit number: ";
cin>>number1;
cout<<"Enter one single-digit number: ";
cin>>number2;

cout<<endl;
cout<<number1<<" "<<number2;

while ((number1!=num1)&&(number2!=num2))
{
What I see here is that neither num1 nor num2 have been initialized. If this is intentional mystery code, I don't like it:mad: . If it's an error, why not document the program enough so I can understand what you are trying to do. :confused:
Ciao, Al

Yeah if people would use descriptive variable names and/or commenting it would be a lot easier and faster to debug programs.
