Solidity provides a rich infrastructure for decision and looping constructs. It provides if...else decision control structures and the for, do...while, and while loops for looping over data variables that can be iterated.

The following chapter will discuss Solidity and contract functions in detail; these are core elements for writing contracts. Blockchain is about executing and storing transactions and transactions are created when contract functions ...
