// Different type of Conversion for data types and variables.
// 1 - Convert Class

// We can use this we want to Convert a variable to another data type,
// except Float (there isn't a ToFloat method in the Convert class)
// so use Double or Decimal. Also can be used in input.
string str = "100";
int num1 = Convert.ToInt32(str);
Console.WriteLine(num1);

int num2 = Convert.ToInt32(Console.ReadLine());
Console.WriteLine(num2);
// num1 will be equal to 100 and num2 will be equal to whatever the input is.
// But if str is null then num1 will be equal to 0.
// And if the input of num2 is null there will be an exception thrown. 

// 2 - Parse Method
// Like the Convert class use this to get input of different data types
// icluding float, but this time not string since string.Parse() does not exist
// because it's no needed (the default type of inputs is string).

string str = "100";
int num1 = int.Parse(str);
Console.WriteLine(num1);

int num2 = int.Parse(Console.ReadLine());
Console.WriteLine(num2);
// num1 will be equal to 100 and num2 will be equal to whatever the input is.
// but this time if both are null an exception will be thrown for each.
// if str is null int.Parse will throw an excpetion and not set the value to 0.

// 3 - casting
// Casting is a way for us to Convert something to another data type for 
// a temporary thing like a single calculation like we do with chars
char letter = 'A';
char nextLetter = (char)(letter + 1);

// in this way we can calculate the next letter of a char by using 
// ascii and then convert it into a char by using (char) before
// it can be used in this format: (data_type)(calcultion or whatever)

// another example
double dbl;
dbl = (double)20 / 8;
