Assigning values not working

[L4dcrusader]

I need to make a program that will determine an odd or even number and when I try to assign a value to "int o" or "int e" it says o and e are "uninitialized local variable 'name' used". The thing is I have to use a "ternary/conditional operator" and I'm unfamiliar with this.

 #include <iostream>

using namespace std;

int main()
{
	int digit;
	int solution;
	int o, e;

	cout << "Please enter a number for me to determine if it is odd or even " << endl;
	cin >> digit;
	
	solution = digit % 2 == 0 ? solution = e : solution = o;
	
	if (solution = e)
	{
		cout << "The number you input is even " << endl;
	}
	else
	{
		cout << "The number you input is odd " << endl;
	}
	

	return 0;
}

Where do you assign values to e or o?

The tutorial http://www.cplusplus.com/doc/tutorial/operators/
shows the use of ternary with an example.


PS. You do have an assignment on line 16. Should you rather compare values there?

Why do you even need e or o?

Why not something like:

int main()
{
	int digit;
	bool solution;

	cout << "Please enter a number for me to determine if it is odd or even " << endl;
	cin >> digit;

	solution = digit % 2 ? false : true;

	if (solution)
	{
		cout << "The number you input is even " << endl;)
