C# Concatenation

Definition:
Concatenation is the process of combining any and all of data types (strings, integers, doubles or floats, chars, a even a boolean).

Syntax:
Here is some examples of how concatenation works and when to use it:

string firstName = "John";
string lastName = "Smith";
string fullName = firstName + " " + lastName;
string gender = "Male";

int age = 25;
int phoneNumber = 1234567890;
int SSN = 101010101;

bool isMarried = true;

Console.WriteLine("Full Name is: "+ fullName );
Console.WriteLine("Age is: " + age + " years old" );
Console.WriteLine("Gender is: " + gender );
Console.WriteLine("Is married?: " + isMarried );
Console.WriteLine("Phone number: " + phoneNumber );
Console.WriteLine("SSN: " +SSN);

// output:
/*
  Full Name is: John Smith
  Age is: 25 years old
  Gender is: Male
  Is married?: True
  Phone number is: 1234567890
  SSN: 101010101
