Prefix and Post fix

Prefix and Post fix

#include<iostream>     // it is  a library used for display
#include<conio.h>      // its is also a library used for input output statement
using namespace std;
// Prefix increment and post fix increment
main()

{
int a=3,b=4;
cout<<".........Prefix increment.........."<<endl;
cout<<"previous value of b="<<b<<endl;   // as we know what is happening here
 cout<<++b<<"=due to prefix increment"<<endl;          /*as form the name prefix increment its increment value before using it in the program
                      like b=4 so ++b mean increment a value before its get use */
cout<<".........Post fix increment.........."<<endl;

cout<<"previous value of a="<<endl;  // as we know what is happening here
cout<<"value of a is =\t"<<a++<<"\\t although ++ sign is there"<<endl;
 cout<<"now here its get increment="<<a<<endl; /* here the value is first incremented then used in the program in the next
                                               statement*/
}
/* Task:
Do same process with for the decrements operator use same codding but just replace ++ sign
with -- sign */
