Storage for seven character sized pointers is allocated to the week pointer, which is a double pointer shown here at line 13, and the malloc function, which returns the pointer's address, is type cast to a double character pointer as well. Each week day string is manually assigned to the array lines 23 through 29, and then the for loop at line 31 outputs each of the array elements one at a time using pointer notation, build and run. And there are the seven days of the week. Now, the point here is two fold, first to show how an array of pointers can be allocated in an extremely clumsy manner.
