Pointer to Pointer Pointer to pointer is a variable that holds the address of another pointer. Declaration datatype ** pointer_name; For example, int **p; //p is a pointer to pointer Initialization The ‘&’ is used for initialization. Eg − int a = 10; int *p; int **q; p =...

The method is indirective one! C provides an operator and data type to solve above problem Pointers • A pointer is a variable that contains the address of a variable. 100 int k=100 &k &k int *pk Variable pk is a pointer points to k contains the address of k ...
In C, there is a strong relationship between pointers and arrays, strong enough that pointers and arrays should be discussed simultaneously. Any operation that can be achieved by array subscripting can also be done with pointers. The pointer version will in general be faster but, at least to t...

constintarray_size=3;intia[array_size]={0,1,2}; If we explicitly specify a list of values, we may not specify the size of the array: the compiler itself will count the number of elements. C++ Pointer A pointer is an object containing the address of another object and allowing indirect...

The array is declared as a raw C-style array, which is mostly useful for operating with pointers. The array is passed with the int arr[] notation of the parameter, but it is converted underneath by the compiler as the pointer to the array, and we can treat it as such in the ...
