ok guys this is my code it dosent appear to to what i want it to.

#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

#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.

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.

[7stud]

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?

[thestien]

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

[thestien]

7stud i compiled and ran the program and it displayed the same result over and over .
i know what your saying though as im not displaying the result of (b)
and sorry i dont know what order to write the code but (a) will = the input form the user.
eventually
i been trying to write this for a week lol
