Reviewing and brushing up my c# skills via HackerRank's 30 days of code challenge.
int i = 5;
double d = 5.0;
string s = "TestString";
// Read and save an integer, double, and String to your variables.
int intVar = Convert.ToInt32(Console.ReadLine());
double doubleVar = Convert.ToDouble(Console.ReadLine());
string stringVar = Console.ReadLine();
// Print the sum of both integer variables on a new line.
Console.WriteLine(i + intVar);
// Print the sum of the double variables on a new line.
Console.WriteLine((d + doubleVar).ToString("F1"));
// Concatenate and print the String variables on a new line
// The 's' variable above should be printed first.
string concatString = s + stringVar;
Console.WriteLine(concatString);
