What is a pointer in programming?
pointers are the variable which stores the address of another variable.
What is a ponters in c-programming?
with the help of pointers we able to store the memory location of any variable. In c the pointer variable is use to store the memory location of any variable. The pointer variable is define as a simple variable but in pointer variable use a special "*" character at the left most side of name of pointer variable. If any variable name have * it means it is a pointer variable it hold the memory location of variable.
C program pointers to pointers examples?
Pointer to Pointer is a double pointer, denoted by (**). Pointer stores the address of the variable and pointer to pointer stores the address of a pointer variable and syntax can be given as int **ptr2ptr;
Array of pointers?
a pointer is a variable that contains memory location of another variable.the value u assign to the pointers are memory address of other variable.
What is pointers in c?
a pointer is a variable .it specify the address of the particular variable ,the & symbol is to specify the address of the variable.
What is an array of pointers to pointers?
A pointer is a variable that stores value of address of a variable. Since a pointer itself is a variable, it is allocated a memory location.Pointer to pointer means a pointer which points to the address of a pointer. In other words a pointer to a pointer has the address of the address of a variable.We can have pointers to int, and pointers to char, and pointers to any structures we've defined, and in fact pointers to any type in C, it shouldn't come as too much of a surprise that we can have pointers to other pointers. If we're used to thinking about simple pointers, and to keeping clear in our minds the distinction between the pointer itself and what it points to, we should be able to think about pointers to pointers, too, although we'll now have to distinguish between the pointer, what it points to, and what the pointer that it points to points.
What is pointer in java?
There is no concept similar to pointers in Java. Pointers are a feature in C programming using which a programmer can access the memory. This was the cause of major catastrophic programming bugs. The creators of Java excluded this feature just to avoid such catastrophic bugs.
How many pointers can be used in a c program?
Answergenerally we use simple pointer, void pointer,null pointer, structure pointer. Answerzero or more (unlimited).
How do pointer work in c program?
Pointer can be defined as variable that is used to store memory address , usually the location another variable in memory. Pointers provide a means through which memory location of a variable can be directly accessed.
What you use in case of pointer in java?
Java does not have pointers
Is it true or false that assigning an address to a pointer variable is valid operation?
Pointers are meant to store adresses.
What is pointer and pointer types and uses of pointer and the meaning of pointer?
The main advantages of using pointers are 1.) Function cannot return more than one value. But when the same function can modify many pointer variables and function as if it is returning more than one variable. 2.) In the case of arrays, we can decide the size of the array at runtime by allocating the necessary space. C has a minimum number of fundamental data types - a single character, a single integer or float, and a few derived data types such as a structure, an enumerated list, and an array. If you want to do much more than that, you make use of pointers. Pointers allow you to dynamically request memory to store off information for use later. They allow you to create linked lists and other algorithmically oriented data structures.
