What would a box-circle diagram look like at point 4 and point 5?

Struct T{int data; struct T* next;}; struct T** p; struct T** q; struct T **r; struct T* c, d; int main() {struct T** a; {struct T* b; a = (struct T**) malloc(sizeof(struct T *))//memory 1 *a = (struct T*) malloc (sizeof(struct T b (struct T));//memory 2 b = (struct T*)malloc(sizeof (struct T));//memory 3 (*b).next= * a; p =&b; b = (struct T*) malloc(sizeof(struct T));//memory 4 (*(*a)).next b;//point 1 c = (struct T*) malloc(sizeof(struct T));//memory 5 p = a; a = c; b (struct T*) malloc(sizeof(struct T))//memory 6//point 2 q = &b; r = &c; a (struct T*) malloc (sizeof(struct T));//memory 7 (*b).next = *a; d = *a;//point 3 free(a); free(b);//point 4}//point 5} Struct T{int data; struct T* next;}; struct T** p; struct T** q; struct T **r; struct T* c, d; int main() {struct T** a; {struct T* b; a = (struct T**) malloc(sizeof(struct T *))//memory 1 *a = (struct T*) malloc (sizeof(struct T b (struct T));//memory 2 b = (struct T*)malloc(sizeof (struct T));//memory 3 (*b).next= * a; p =&b; b = (struct T*) malloc(sizeof(struct T));//memory 4 (*(*a)).next b;//point 1 c = (struct T*) malloc(sizeof(struct T));//memory 5 p = a; a = c; b (struct T*) malloc(sizeof(struct T))//memory 6//point 2 q = &b; r = &c; a (struct T*) malloc (sizeof(struct T));//memory 7 (*b).next = *a; d = *a;//point 3 free(a); free(b);//point 4}//point 5}
