What are the Indirection?Explain with an example? 
You have a pointer, what do you do with it? Because it�s part of your program,you can�t write your address on it and nail it to a tree so that your friends can find your home. You can, however, assign to a pointer the address of a variable and pass it to a function, and then the function can find and use the variable.
  C operator * is called the indirection operator.C to use whatever the pointer variable is pointing to and use the value contained in the memory that the pointer is pointing to.
