Program Of Unary Operators In C++

#include<iostream.h>

#include<conio.h>

main()

{

clrscr();

int a,b,c,d,e,f,g,h;

a=10;

b=++a;    //b=11 , a=11

c=--a;   //c=10 , a=10

d=a--;   //d=10, a=9

e=a++;   //e=9,a=10

f=a++;  //f=10 , a=11

g=++a;  //g=12, a=12

h=a--;  //h=12, a=11

cout<<"\n a="<<a;

cout<<"\n b="<<b;

cout<<"\n c="<<c;

cout<<"\n d="<<d;

cout<<"\n e="<<e;

cout<<"\n f="<<f;

cout<<"\n g="<<g;

cout<<"\n h="<<h;

Define Unary Operator

Unary operators operate on one operand(variable or constant). There are two types of unary operators- increment and decrement.
