c++ structure pointers

Example code:

struct MyStruct {
   char c;
   int i;
   double d;

   char* get_c() {
      return &c;
   }
   int* get_i() {
      return &i;
   }
   double* get_d() {
      return &d;
   }
};

void foo() {
   MyStruct s;
   char* pc = s.get_c();
   *pc = 'a';
   *(s.get_i()) = 1;
   double& rd = *(s.get_d());
   rd = 3.14;
}

This code uses a local pointer variable, a temporary, and a local reference to access members of the struct. All of these should work.

Note my use of accessor functions: you didn't state what you intended, but if you're accessing these member variables multiple times, it's usually a good idea to have a function for that purpose.

P.S.:

This error pretty clearly states what you did wrong: the right hand side obviously evaluates to an integer value, but the left hand side evaluates to a type that the compiler can't assign an integer to. The reason is that your pointer variable is not of the appropriate type - it must be pointer to int, or pointer to any other type that an int can be converted into, e. g. pointer to long or pointer to double.
