Flow of a Program

Sequence, selection, iteration shape control flow.

Control Structures

  • Sequence: statements run in order.
  • Selection: if / switch choose branches.
  • Iteration: loops repeat.

Runtime Model

  • CPU executes instructions; branching alters instruction pointer.

Mini Example

  • int sum = 0;
  • for(int i=1;i<=3;i++){ sum += i; }
  • if(sum > 3) System.out.println(sum);
