rbroller815 · #1 02-Apr-2007, 22:31

CPP / C++ / C Code:

double getA ()
{

	int A
	
	
	cout<<" Please enter the A coefficient ";
	cin>>A;

	if (A==0)
	cout<<" Please enter another value that is non-zero";
	cin>>A;
	else 
	return A;
	
	
}

Thats the function i am working on i know its wrong but i need help doing the loop it needs to take in A and then it needs to c if it is zero and if it is then return an error then call for another answer till it is right. help thank you.

When I pointed out

Quote:

Do what that Yellow on Red post titled Read This explains.

You seem to have missed 1A, 2B, 2F, 3, and 6

And you need to look at WHILE loops, like I already suggested. Did you? What you have is just about there. You are simply missing the WHILE statement. Think about where it should go and put one in. We'll help you fix it if you miss. Like we always say, we won't do it for you. But we'll help you fix it.

CPP / C++ / C Code:

double getA ()
{
  int A;
  cout<<" Please enter the A coefficient ";
  cin>>A;
while(A==0)
 {
    cout<<" Please enter another value that is non-zero"<<endl;
    cin>>A;
 }
	
   return A;
}

This will be ok!I think you should read the c++ books first.
