error: use of deleted function 'ClassName::ClassName(const ClassName&)' - c++

Question

I keep getting this error when compiling, but I don't know why. I have looked at this post and this one, but they appeared to be different problems.
The relavent code structure is:
// main.cpp
#include "MyClass.h"
int main() {
MyClass newClass = MyClass();
}
// MyClass.h
#include <string>
#include <sstream>
#include <vector>
using namespace std;
class Node;
class MyClass {
private:
vector<Node*> nodes;
int number;
stringstream fileInfo;
public:
MyClass();
~MyClass();
};
// MyClass.cpp
#include "MyClass.h"
MyClass::MyClass() {
number = 1;
}
MyClass::~MyClass() {}
The error I get when compiling is:
main.cpp: In function 'int main()':
main.cpp:4:29: error: use of deleted function 'MyClass(const MyClass&)'
MyClass new Class = MyClass();
^
In file included from main.cpp:1:0:
MyClass.h:7:7: note: 'MyClass::MyClass(const MyClass&)' is implicitly deleted because the definition would be ill-formed:
class MyClass {

I have tried initializing all the class members in the constructor, but that didn't change the error. Other than that I can't think of what is wrong.

Answer 1

The problem is that your class is not copy-able because it contains a std::stringstream (which is itself not copy-able). This results in its copy constructor being deleted, which is what the compiler is trying to tell you. To fix this, simply don't use the copy-initialization syntax in your main function.
int main() {
MyClass newClass;
}
