In first case the mem is allocated for struct but not for pName. so you will get runtime error as "Segmentation fault".

In second case also you will get the same, because here allocating memory and then freeing the object and then using in the printf statement. So obj is freed and your refering an unallocated memory. so you will get the same error.
