Understanding Pointers In C By Yashwant Kanetkar Pdf Verified

In C, arrays and pointers are bound tightly together. An array name is fundamentally a constant pointer pointing to the very first element of the array. int arr[3] = 10, 20, 30; Use code with caution. arr yields the address of the 0th element ( &arr[0] ). *(arr + 1) yields the value of the 1st element ( 20 ). *(arr + 2) yields the value of the 2nd element ( 30 ).

By passing addresses, the function manipulates the actual memory locations of the original variables.
