Control structures

Solidity supports if, else, while, for, break, continue, return, ? : control structures.

Here is an example to demonstrate the control structures:

contract sample{     int a = 12;     int[] b;     function sample()     {         //"==" throws exception for complex types          if(a == 12)         {         }         else if(a == 34)         {         }         else         {         }         var temp = 10;         while(temp < 20)         {             if(temp == 17)             {                 break;             }             else             {                 continue;             }             temp++;         }         for(var iii = 0; iii < b.length; iii++)         {         }     } }
