  6. {
  7. //Execute this part.
  8. }

Simple Code

  1. static void Main(string[] args)
  2. {
  3. int a = 2; //initialization and declaration..
  4. int b = 3; //initialization and declaration..
  5. int c; //initialization..
  6. c = a + b; //doing sum of a & b and store in c..
  7. if (c == 5) //checking condition..
  8. {
  9. Console.Write("Condition True.."); //true condition code..
  10. }
  11. else //false statement
  12. {
  13. Console.Write("conditiion false.."); //false condition code..
  14. }
