Pointers in C language is a variable that stores/points the address of another variable. A Pointer in C is used to allocate memory dynamically i.e. at run time . The pointer variable might be belonging to any of the data types such as int, float, char, double, short etc. Pointer Syntax : data_type *var_name; Example : int *p;  char *p; Example:- int * ptr ; Where * is used to denote that “p” is pointer variable and not a normal variable. int a = 5 ; int * ptr = NULL ; ptr = & a ; This assigns the value of the address of  a  to  ptr . For example, if  a  is stored at memory location of 0x8130 then the value of  ptr  will be 0x8130 after the assignment. To dereference the pointer, an asterisk is used again: Let's see an example program #include <stdio.h> int main () { int var1 ; char var2 [ 10 ]; printf ( "Address of var...
