I need a pointer to a random type of data (void *) would be the right thing to use right? it seems I''m using wrong. How can you set green with yellow ? int green=20; int blue =20; void *yellow; //this may need to point to int , bool ,float ,ect. int * red; int main(int argc, char* argv[]) { char Text[40]; //this works fine red=&green; *red=50; //how do I get this to work, I need yellow to be void * yellow=&green; //ok *yellow=(void *)50; //error C2100: illegal indirection //how do I fix it. It does needs to be a void* so it can point to floats and bools too. sprintf(Text, "%u", green); //50 good printf(Text); sprintf(Text, "%u", blue); //? needs to be 50 too. printf(Text); return 0; }

True. Was trying to simplify a concept that can be difficult for people who haven''t fully grasped pointers as a concept yet.
