    need a little help please

    ok guys this is my code it dosent appear to to what i want it to.
    Code:
    #include <iostream>
    
    using namespace std;
    
    int main ()
    {
    int a;      
    int b;      
    int c;     
    int d;      
    b=1;
    c=a*b+b;
    d=20;
    
    cout<<"please enter to number\n";
    cin>>a;
    cin.ignore();
    
    while (c<d){
    b++;
    cout<<c;
    }
    cout<<c;
    cin.get();
    }
    it just throws 3's everywhere lol is this a valid way to use a while loop?i mean it wont do the ++ thing with b??thank you in advance

    Code:
    #include <iostream>
    
    using namespace std;
    
    int main ()
    {
    int a;      
    int b;      
    int c;     
    int d;      
    b=1;
    c=a*b+b;
    a is unintialized at this point.

    Code:
    d=20;
    
    cout<<"please enter to number\n";
    cin>>a;
    cin.ignore();
    
    while (c<d){
    b++;
    cout<<c;
    }
    Neither c nor d are changing in this loop. As written, the b++ line does not affect how many times the loop will execute.

    c=a*b+b;
    What does 'a' equal in that statement?

    i mean it wont do the ++ thing with b?
    How do you know? What if I told you it did. How would you prove me wrong?

    Code:
    cout<<"please enter to number\n";
    cin>>a;
    cin.ignore();
    
    while (c<d){
    b++;
    cout<<c;
    }
    is there any way i can get (b++) to control the loop?
    sorry im a complete newb but i try
