In that situation pointer comparison is invalid. if(pc1>pc2)// illegal statement { } Note:The C standard does not allow the arithmetic operation on void pointers but GNU C allows with assuming the size of the void is 1. To know about the void pointer See this Link:Use of void pointer...
etc. However, as we know that pointer contains the address, the result of an arithmetic operation performed on the pointer will also be a pointer if the other operand is of type integer. In pointer-from-pointer subtraction, the result will be an integer value. Following arithmetic operations ...
Pointer Arithmetic Arithmetic can be performed on pointers. However, in pointer arithmetic, a pointer is a valid operand only for the addition(+) and subtraction(-) operators. An integral value n may be added to or subtracted from a pointer ptr. Assuming that the data item that ptr points ...
C++ Pointer Arithmetic - As you understood pointer is an address which is a numeric value; therefore, you can perform arithmetic operations on a pointer just as you can a numeric value. There are four arithmetic operators that can be used on pointers: ++
Pointer arithmetic in C programming language C pointer to an array Evaluation of statement '*ptr++' in C language Pointer and non-pointer variables declarations together in C? Pointer to an array of integers in C language [Declarations, Initialization with Example] Pointer to Pointer (Double Point...
Pointer arithmetic in C programming language C pointer to an array Evaluation of statement '*ptr++' in C language Pointer and non-pointer variables declarations together in C? Pointer to an array of integers in C language [Declarations, Initialization with Example] ...
C/C++ is powerful because of pointers. The pointers are used to represent the address of some memory locations. Pointers can be involved in arithmetic operations, for example, int *p; p ++ means p is the pointer to integer and p moves to the next int (4 byte offset). The pointers are...
Pointer Arithmetic Here, we have a simple program to illustrate the concepts of both incrementing a pointer and using a compound assignment operator to jump more than one element in the array. First, we initialize the pointer p to point to the array x. In this case, we are initializing th...
How Actually Pointers are Adjusted in Computer Memory Single , Double , Triple Pointer The concepts of LValue and RValue that most of us don’t know Type Mismatch Arithmetic Operation on Pointer Pre and Post Increment Pointer Generic , NULL Pointers ...
Pointer vs Array in C C program to display relation between pointer to pointer Explain the Union to pointer in C language Difference between pointer and array in C Sum of array using pointer arithmetic in C++ Sum of array using pointer arithmetic in C Difference Between Array and Poi...
