Number of semicolons.

This is a simpler token count than Statements: since each clause of a for loop's header counts as its own statement, it's actually a single semicolon that can end multiple statements at once — cyclomaticDemo()'s bool a = true, b = true, c = true; declares three variables (three declarative statements) with only one semicolon. Other lines, like a block or an if without a trailing statement, have none.

For example:


void SayHello::printHello() {
  switch (i) {
    case 0:
      cout << "Hello World" << endl;
    case 1:
      cout << "HELLO WORLD!" << endl;
    default: // a comment here
      for (int m = 0; m < j; m++);
      cout << "hello world" << endl;
  }
#ifdef A_VERY_NICE_VARIABLE

  cout << "Inactive Line" << endl; // Inactive
#endif

}

printHello() has 6 semicolons: one ending each of the three cout statements (lines 14, 16, 19), and three inside the for loop's header on line 18 (m = 0;, m < j;, and the empty body's own ;). The semicolon on the inactive cout line inside the #ifdef block (line 23) doesn't count.
