There are 8 different types of Soils present in India. They are primarily differentiated on the basis of composition and structure. They are ::

1.  Alluvial soils, 

2.  Black soils,

3.  Red soils,

4.  Laterite and Lateritic soils,

5.  Forest and Mountain soils,

6.  Arid and Desert soils,

7.  Saline and Alkaline soils and

8.  Peaty and Marshy soils.

The area of the four states approximately, are as follows : Madhya pradesh 443000 sq km; Rajasthan 342000 sq km; Uttar pradesh 294000 sq km.

struct emp

{

     char n[20];

      int age;

};

main()

{

    struct emp e1 = {"Dravid", 23};

   struct emp e2;

   scanf ("%s %d",e2.n, & e2.age);

   if( structcmp (e1,e2) ==0)

        printf ("The structures are equal");

   else

         printf ("The structures are unequal");

}

structcmp ( struct emp x, struct emp y)

{

     if (strcmp (x.n,y.n) ==0)

           if (x.age == y.age)

            return (0);

            return (1);

}

In short, if you nee to compare two structures, you'll have to write your own function to do so which carries out the comparison field by field.
