Compiler Error C3484

expected '->' before the return type

Remarks

You must provide -> before the return type of a lambda expression.

To correct this error

• Provide -> before the return type.

Example

The following example generates C3484:

// C3484a.cpp

int main()
{
   return []() . int { return 42; }(); // C3484
}

The following example resolves C3484 by providing -> before the return type of the lambda expression:

// C3484b.cpp

int main()
{
   return []() -> int { return 42; }();
}
