    //................................Quiz...........................//

	//Write code to print Sum of numbers from 1 to 10 using for loop:


	//int sum = 0;
	//for (int i = 1; i <= 10; i++) {
	//	sum = sum + i;
	//}
	//cout << sum << endl;

	// but what if i want to Solve it without loops ?

	//int num = 10,sum=0;
	//sum = num * (num + 1) / 2;
	//cout << sum;

	//................................Arrays...........................//

	//int myNumbers[5] = { 10, 20, 30, 40, 50 };
	//for (int i = 0; i < 5; i++) {
	//	cout << myNumbers[i] << "\n";
	//}

	// cout << sizeof(myNumbers);  // what is the result ?

	//int getArrayLength = sizeof(myNumbers) / sizeof(myNumbers[0]);
	//cout << getArrayLength;

	// ..............................The best way...........................//

	//int myNumbers[5] = { 10, 20, 30, 40, 50 };
	//for (int num : myNumbers) {
	//	cout << num << "\n";
	//}
	// ..............................2D Arrays...........................//

    //   string letters[2][4] = {
    //     { "A", "B", "C", "D" },
    //     { "E", "F", "G", "H" }
    //   };

	//cout << letters[1][2];  //What is the result ?

	// ..............................references...........................//
    //string food = "Pizza";
    //string& meal = food;

    //cout << food << "\n";  // Outputs Pizza
	//cout << meal << "\n";  // Outputs Pizza


	//meal = "Hamburger";
	//cout << food << "\n";  // Outputs Hamburger

	// ..............................pointers.............................//

    //string food = "Pizza";  // A food variable of type string
    //string* ptr = &food;    // A pointer variable, with the name ptr, that stores the address of food
    //
    //// Output the value of food (Pizza)
    //cout << food << "\n";
    //
    //// Output the memory address of food (0x6dfed4)
    //cout << &food << "\n";
    //
    //// Output the memory address of food with the pointer (0x6dfed4)

    //cout << ptr << "\n";  //what if ( ,& ,* )?
