The return value is missing after 'return'DRT-W1606

The analyzer produces this diagnostic when it finds a return statement without an expression in a function that declares a return type.

Example

The following code produces this diagnostic because the function f is expected to return an int, but no value is being returned:

int f() {
  return;
}

Common fixes

Add an expression that computes the value to be returned:

int f() {
  return 0;
}
