check addresses are correct or not

    /* cosider 3 variables and find the addresses ,first two variables
        addresses difference is equal to another two variables
        addresses difference. */

#include<stdio.h>
main()
{
int x=10,y=20,z=30;
clrscr();
printf("address of x=%d\n",&x);
printf("value of x=%d\n",x);
printf("address of y=%d\n",&y);
printf("value of y=%d\n",y);
printf("address of z=%d\n",&z);
printf("value of z=%d\n",z);
getch();
}

output :-
address of x= -12
value of x= 10
address of y= -14
value of y= 20
address of z= -16
value of z= 30

program for increment & decrement operators

    Program for Increment & Decrement Operators

   Increment operators are divided into 2 types(++).
   * post increment.
       a++;
       The original value of 'a' is assigned to 'a' first,increment
       (+1) to the next operation.
   * pre increment.
       ++a;
       The incremented value(+1) is assigned first,after perform the
       operation.

      example1 :-

         #include<stdio.h>
       main()
       {
          int a =6;
          clrscr();
          printf("y=%d",y++);
          getch();
       }

      example2 :-

        #include<stdio.h>
        main()
       {
             int x =10;
             clrscr();
           printf("value of x =%d",x++);
             printf("value of x =%d",--x);
             printf("value of x =%d",x--);
             printf("value of x =%d",++x);
             printf("value of x =%d",x++);
             getch();
        }

       example3 :-

       #include<stdio.h>
       main()
      {
       int x =6;
       clrscr();       printf("%d%d%d",x++,++x,x--);
       getch();
      }
     example4 :-

      #include<stdio.h>
      main()
     {
          int i,j =4;
          clrscr();
          i =j++ * ++j * j--;          printf("\ni=%d,j=%d",i,j);

                                      while(condition);
                                   }

               Example :-

                                  #include<stdio.h>
                                  main()
                                  {

                                       int i=10;
                                       do
                                       {
                                           printf("%d\n",i);
                                            i=i+1;

(or)

i++;

}

while(i<=15);
return 0;

getch();

}

             output:-
                           10
                           11
                           12
                           13
                           14
                           15
