Compiler Error C2048

  • Artikkeli

more than one default

A switch statement contains multiple default labels. Delete one of the default labels to resolve the error.

The following sample generates C2048:

// C2048.cpp
int main() {
   int a = 1;
   switch (a) {
      case 1:
         a = 0;
      default:
         a = 2;
      default:   // C2048
         a = 3;
   }
}

Possible resolution:

// C2048b.cpp
int main() {
   int a = 1;
   switch (a) {
      case 1:
         a = 0;
      default:
         a = 2;
   }
}
