• Program Layout

  • Statements end with semi-colons.
  • Blocks of statements delimited by braces.

• Condition execution

  if(condition) { ... } else { ... }
  

• Conditional Loops

  while(condition) { .... }
  
  do{ ... } while(condition);
  

• Two kinds of for : Iteration

• Multiway Branching : switch

Iteration

• for loop inherited from C.

  for ( init; cond; update;) { ... }
  

  • init → Initialization
  • cond → termination condition
  • update

• Second type of for loop

  • In style of Python

  for(type x : a)
  {
  	//do something with x
  }
  

  • The loop variable MUST be declared in local scope for this version of for.

    • i.e. cannot do something like

    int x;
    for( x : a)   //error . should be for(int x:a)
    {
    	//do
    }
    

Multiway branching

• switch statements
• Need to explicitly break out of switch or else “fall through” from one case to the case below.
• In case statements: the option given should be a constant → Cannot use conditional Expressions
