Well, in C, the name of an array, is actually a pointer to the first element of the array.Confused? Let's try to understand this better, and use our "memory address example" above again. The memory address of the first element is the same as the name of the array:...
In the line 'int arr[5];' we are declaring an array of 5 integers. So the program allocated a buffer of 20 bytes because each integer takes 4 bytes. Then we assign an arbitrary integer to each of the positions, and then we print them on a loop. However, what if we want to print...
Just like we can declare an array of int, float or char etc, we can also declare an array of pointers, here is the syntax to do the same. Syntax: d…
To create a pointer to an array, the following syntax is followed: data_type (*var_name)[size_of_array]; The pointer that points to the first element of the array and the one that points to the whole array are different. Because the first value is a single integer. The following ...
to access the values pointed to by the pointers in an array, you'd first use the array index to access the pointer, and then the dereference operator to get the value. in c/c++, *arr[2] would get you the value pointed to by the third pointer in the array arr. can i have an ...

Precedence:Operator precedence describes the order in which C reads expressions. (): this operator is used to declare and define the function. []: this is an array subscript operator. *: this is a pointer operator. Identifier: this is the name of a pointer. ...
But In C language we do not have the freedom to start the array index from any other number than zero, and language strictly sticks to zero as start index of array. It is because in C the name of an array is a pointer, which is a reference to a memory location. Therefore, an expr...
arr2 is a pointer (the parenthesis block the right-left) to an array of 8 integers. int *(arr3[8]); 1. arr3 is an array of 8 pointers to integers. This should help you out with complex declarations. Here is a great article about reading complex declarations in C:unixwiz.net/tech...
arr3 is an array of 8 pointers to integers. This should help you out with complex declarations. Here is a great article about reading complex declarations in C:unixwiz.net/techtips/reading-cdecl.html The ``Clockwise/Spiral Rule'' There is a technique known as the ``Clockwise/Spiral Rule'...
