struct data structure
This line of code is allocating memory dynamically using the malloc() function for a structure called "node". The size of the memory block allocated is determined by the sizeof() function and is the size of the structure "node". The function returns a pointer to the allocated memory block, which is then assigned to the variable "p". This is commonly used in C programming to dynamically allocate memory for data structures at runtime.
