Pointers are variables that hold address of another variable of same data type. Pointers are one of the most distinct and exciting features of C language. It provides power and flexibility to the language. Although pointer may appear little confusing and complicated in the beginning, but trust me its a powerful tool and handy to …
When an array is declared, compiler allocates sufficient amount of memory to contain all the elements of the array. Base address which gives location of the first element is also allocated by the compiler. Suppose we declare an array arr, int arr[5]={ 1, 2, 3, 4, 5 }; Assuming that the base address of arr …
Like we have array of integers, array of pointer etc, we can also have array of structure variables. And to make the use of array of structure variables efficient, we use pointers of structure type. We can also have pointer to a single structure variable, but it is mostly used with array of structure variables. …
Pointer arithmetic is very important to understand, if you want to have complete knowledge of pointer. In this topic we will study how the memory addresses change when you increment a pointer. 16 bit Machine ( Turbo C ) In a 16 bit machine, size of all types of pointer, be it int*, float*, char* …
Pointer in function parameter list is used to hold address of argument passed during function call. This is also known as call by reference. When a function is called by reference any change made to the reference variable will effect the original variable. Example: Sorting an array using Pointer #include <stdio.h> #include <conio.h> void sorting(int …
