Missing a break in example

[fv3rdugo]

In the example, the default option is empty, it has a comment line, this would generate an error:

expected primary-expression before the '}' token

Normally, the default option has statements, but if it is not the case, insert a break line is a solution

switch (estat) {
    case 'A':
      // statements
      break;
    case 'M':
      // statements
      break;
      default:
      // statements
      break;  //not necessary if you have statements
  }
