Visual Studio editor thinks that my declared vector is actually a declared function

vaderboi (140)
I am trying to create a class that, when instantiated in to an object, will place a number of randomly generated elements in to a vector. Right off the bat, the Visual Studio editor thinks that my declared vector variable is actually a function. When I hover over "listOfNums", I get this error:

"std::vector<int> SortedArray::listOfNums(size_t numOfElements)
Function definition for 'listOfNums' not found."

Shouldn't the C++ compiler recognize that "listOfNums" is using a constructor to take size "numOfElements"?

Here is my code:

1
2
3
4
 
class SortedArray{
   private:
		std::vector<int> listOfNums(size_t numOfElements);
}

Don't just "hover". Compile it and post all of the error output (including any that scrolled off the top). The error presumably begins somewhere else.

If you want do define a function that takes a size_t and returns a vector of int, how would you write it?

Okay will do. Will let you all know what the error is.

#include<iostream>
#include <vector>

class SortedArray
{
public:
	SortedArray(size_t numberOfElements = 5);

	std::vector<int> listOfNumbers;
};

SortedArray::SortedArray(size_t numberOfElements)
	: listOfNumbers(numberOfElements)
{

}

int main()
{
	SortedArray sa1;
	SortedArray sa2(19);

	std::cout << "sa1 capacity: " << sa1.listOfNumbers.capacity() << "\n";
	std::cout << "sa2 capacity: " << sa2.listOfNumbers.capacity() << "\n";

	return 0;
}
 
sa1 capacity: 5
sa2 capacity: 19

Yeah, I wasn't even thinking, man. That's a function declaration. You need to do it like CodeMonkey shows.

Took your advice, CodeMonkey. I looked up member initialization in my textbook and created the constructor you recommended.
