error: expected primary-expression before ‘)’ token - c++

Question

I have tried many times to solve this problem but i got nothing.
The main purpose of this code is saving pair keys (Public and Private) in nested class NslObject::KeyK or NewKeyPair1.
.cpp file
unsigned long int keyLength = 10;
//KeyPair ADD(RSA::GenerateKeyPair(keyLength));
NslObject::KeyK(RSA::GenerateKeyPair(keyLength));
typedef NslObject::KeyK NewKeyPair1;
NewKeyPair1(RSA::GenerateKeyPair(keyLength));
//NslObject::
Key OtmanK(NslObject::Get_PublicKey(NewKeyPair1));
.h file:

//--------------------------------------------------------
};
so, the problem in this line in cpp file :
Key OtmanK(NslObject::Get_PublicKey(NewKeyPair1));
when i tried to compile this project, i got this Error message:
object.cc:87: error: expected primary-expression before ‘)’ token
please, help me.
when i tried to make a directed call for key class, the other problem was appeared such as :
unsigned long int keyLength = 10;
//KeyPair ADD(RSA::GenerateKeyPair(keyLength));
NslObject::KeyK(RSA::GenerateKeyPair(keyLength));
typedef NslObject::KeyK NewKeyPair1;
NewKeyPair1(RSA::GenerateKeyPair(keyLength));
//NslObject::
//Key OtmanK(NewKeyPair1.GetPublicKey());
std::string message = "othman Alkilany";
// NslObject::NewKeyPair.GetPrivateKey()
std::string cypherText = RSA::Encrypt( message, NewKeyPair1.GetPublicKey());
the Error Message is :
error: expected primary-expression before ‘.’ token

Answer 1

I guess your issue is in the second line here:
typedef NslObject::KeyK NewKeyPair1;
NewKeyPair1(RSA::GenerateKeyPair(keyLength));
Resolving the typedef you've essentially written the following:
NslObject::KeyK(RSA::GenerateKeyPair(keyLength));
So you can clearly see you're missing the variable name for this line.
To fix this, name the variable/object:
NewKeyPair1 somekeypair(RSA::GenerateKeyPair(keyLength));
However, I guess you misused the typedef anyway? Did you try to name that NewKeyPair1? Something like this:
NslObject::KeyK NewKeyPair1(RSA::GenerateKeyPair(keyLength));
