Summary
| Description |
English: Some examples of control flow graphs (CFG):
(a) the CFG of a if-then-else (b) a while loop (c) a natural loop with two exits, e.g. while with an if...break in the middle; non-structured by reducible (d) an irreducible CFG: a loop with to entry points, e.g. goto into a while loop
