Each pointer is associated with some type of data. Their internal representation does not depend on the internal type: both the size of memory occupied by an object of the pointer type and the range of values are the same. The difference is how the compiler perceives the addressable object....

There is one difference between an array name and a pointer that must be kept in mind. A pointer is a variable, so pa=a and pa++ are legal. But an array name is not a variable; constructions like a=pa and a++ are illegal. Pointers and integers are not interchangeable.Zero is the ...
Basically, “array” is a“pointer to the first element of array”but “&array” is a“pointer to whole array of 5 int”. Example: intarray[5];cout<<"array = "<<array<<" : &array = "<< &array<<endl;cout<<"array + 1 = "<<array+1<<" : &array + 1 = "<< &array+1;...

Note: Only when two pointerspoint to elements in the same array, pointer subtraction is meaningful, meaning thesubscript difference of the element pointed to by the pointer; when the elementpointed to by the two pointers is not in the same array,undefined ...
traversing an array of pointers is similar to navigating a regular array; you'd typically use a loop. the difference is in how you access the values. when you reach each pointer, you'd dereference it to get the value it points to. this allows you to perform operations on the actual ...
