'+' : pointer addition requires integral operand

An attempt was made to add a nonintegral value to a pointer using the plus ( + ) operator.

The following sample generates C2111:

// C2111.cpp
int main() {
   int *a = 0, *pa = 0, b = 0;
   double d = 0.00;
   
   a = pa + d;   // C2111
   a = pa + b;   // OK
}
