C Pointers

A pointer is a variable that stores the address of some other variable. With the exception of several other variables that hold values of a given type, the pointer holds the address of a variable.

  1. C Pointers      Pointers in C    Pointers in C are clean, and learning a laugh. Some ​C language tasks are accomplished with                   guidance more easily, and other duties, including the complex reminiscence distribution,             can not be done by using pointers. So learning hints in becoming a super C programmer will                 become important.    What are the Pointers?    In C language, the guidelines are basically a variable that is acknowledged to save the deal                 with another variable, and the variable may be types, array, function, int, char, or any other               pointer from these. However, in a 32-bit layout, the architecture is responsible for the size of               the pointer, the measurements of a pointer are simply 2 bytes.    For instance, an integer variable holds (or you might say stores) an integer value, but an               integer pointer holds an integer variable's address. With the aid of examples, we will be             speaking guidelines in the ​C programming tutorial​.    The general type of a statement for a pointer variable is −    type *var-name;    KEY POINTS TO REMEMBER ABOUT POINTERS IN C:                                                                                                                                   

  2. A normal variable stores the price whereas the pointer variable shops the cope with             of the variable.  The content material of the C pointer always is an entire quantity i.E. cope with.  The C pointer is always initialized to null, i.e. Int * p = nonzero.  The value of the null pointer is 0.  The & symbol can be used to get the variable's address.  * symbol is used to get the fee of the variable that the pointer is pointing to.  If NULL is assigned to a pointer in C it indicates that it points to nothing.  Two pointers can be subtracted to recognize how many factors are available             between these pointers.  But, Pointer addition, multiplication, division are not allowed.  The length of any pointer is 2 byte (for the 16-bit compiler).                  ● ● ● ● ● ● ● ●             ● ●   PROGRAM EXAMPLE ON POINTERS IN C:    #include<stdio.h>    int main(){    int num=10;    int *p;    p=&num ;    printf("Print the Address of p variable = %x \n",p);  printf("Print Value of p variable = %d \n",*p);  return 0;    }   Original Source
