string concatenation

We all know what is string, String is a datatype which is used to store collection of characters(Word or sentance). String Concatenation is the process of appending one string to the end of another string. We can append one string to another string using '+' symbol.

NOTE:
Arithemetic Addition(+) will only takes place if both the LHS(Left hand side) and RHS(Right Hand Side) of the '+' are numerical datatypes(datatypes which used to store intergers and decimal values). Else if even one side is a non numerical datatype system will simply merge first datatype value to second.

CODE

static void Main(string[] args) {
    string text1 = "CODERS";
    string text2 = "CAPSULE";
    //'+' present below will simply merge text1 and text2
    string finalText = text1 + text2;
    Console.WriteLine(finalText); //Output : CODERSCAPSULE

    int number = 25;
    string text = "age";
    string finalResult = number + text;
    Console.WriteLine(finalResult); //Output : 25age
}

Exercises
Take below values and Experiment adding them
1. "He is " + 25 + " years old"
2. "It's " + true;
3. "Coders" + "Forum"
4. "The pi value is " + 3.14159265359
