Your Function definitions are different to the declaration.

void getPlan_Minutes(int A, int B);
void getPlan_Text(int& A, int& B);


void getPlan_Minutes(char& PLAN, int& MINUTES,double& A,double& B)

void getPlan_Text(char PLAN,int Text,double& A, double& B)


These things must match.

how should it be sir
TheIdeasMan (6817)
Make the arguments in the declarations, the same type as the arguments in the function definition.

That's because you're not calling your outputBill function.

What result do you get?

What result do you expect to get?
