#pointer variable

Pointers Expression:- Like any other variables, pointer variable can be used in expressions. In a program all the following operations are valid. 1. C allows us to add or subtract integers from pointers. sum=sum +*p1; 2. Also short hand operators are allowed sum+=*p1; ans = *p1++; This will cause the pointer p1 to point to…

Pointer Variables

 Did you know you may initialize a pointer variable WHILE declaring it?

int i;

int *p = &i;

YUP! ...Wait don’t freak out! There is an even better way!

int i, *p = &i;

Don’t forget to call it!

printf("%d\n", *p);

There are many pointers available to us!

The following can point to a variable of its initialized value:

int *p;

float *q;

double *r;

char *s;
