Initilize constructor of class from another class

This might help you The problem is that A doesn't have a default constructor (because if you define another constructor and default one is not generated) and so A objects cannot be default constructed.
The solution is to use constructor initialization lists for every constructor of B where you call the appropriate constructor for tmp.
class B {
   A tmp;

public:
   B() : tmp(4) {}
};

class B {
  A tmp{4};

public:
  B() {};
}

initilize a struct array in a class constructor in c++

seems to work fine struct Foo myarray[]; should be struct Foo *myarray; if you're going to go with it in a dynamic approach. Otherwise, if you want it to be an unspecified static I think it has to have an initialization list.

cant initilize custom class

Any of those help You haven't implemented a "description" method in your class, so NSLog has nothing it can print out.
Here's how you could do it:
@implementation Account

- (NSString *)description
{
  return [NSString stringWithFormat:@"<Account ID %@>", self.accountID];
}

@end

 @synthesize deviceID = _deviceID;
 @synthesize deviceName = _deviceName;
 @synthesize deviceToken = _deviceToken;
 @synthesize type = _type;
 @synthesize oAuthCode = _oAuthCode;
 @synthesize accountID = _accountID;
 @synthesize os = _os;

I hope this helps . I have 2 different classes, Employee, PersonnelManager. I am trying to declare and instantiate an array of Employee in PersonnelManager. without using inheritance, just two completely seperate classes , You can initialize the array like below - 
public PersonnelManager() {
        EmployeesArray= new EmployeesArray[5]; 
    }

public PersonnelManager(int size) {
            EmployeesArray= new EmployeesArray[size]; 
        }
