Program to arrange string characters in Non Alphabetical order.

Solution:

void main()
{
     int i,j;
    char ch,s[20];

    printf("Enter the string: ");
    gets(s);

    printf("\nString is :");
    puts(s);




    for(i=0; s[i] != '\0'; i++)
    {
        for(j=i+1;s[j] != '\0'; j++)
        {
           if(s[i] < s[j])//checking a character at index i and j,if character
           {//at index i is greater than character at j index, then we are swapping those character.
               ch = s[i];
               s[i] = s[j];
               s[j] = ch;
           }
        }
    }

     printf("\nString in Non Alphabatical order is : ");
     puts(s);
}

Output1

Enter the string: ABCD

String is : ABCD
String in Non Alphabetical order is : DCBA

Output2

Enter the string: LMNO

String is :LMNO
String in Non Alphabetical order is : ONML

Output3

Enter the string: PQRS

String is :PQRS
String in Non Alphabetical order is : SRQP

defining a function 'not_dict' which will arrange the character in non alphabetical order.

void not_dict(char s[])
{
    int i,j;
    char ch;

    for(i=0; s[i] != '\0'; i++)
    {
        for(j=i+1;s[j] != '\0'; j++)
        {
           if(s[i] < s[j])
           {
               ch = s[i];
               s[i] = s[j];
               s[j] = ch;
           }
        }
    }

}

Using above define function 'not_dict()':

void main()
{
    char s[20] = "abcxyz";

    not_dict(s);
   printf("String In Non Alphabatical order is: ");
    puts(s);
}

Output1

String In Non Alphabetical order is: zyxcba

Using above define function 'not_dict()':

void main()
{
    char s[20] = "DCBA";

    not_dict(s);
   printf("String In Non Alphabatical order is: ");
    puts(s);
}

Output2

String In Non Alphabetical order is: DCBA

Using above define function 'not_dict()':

void main()
{
    char s[20] = "LMNO";

    not_dict(s);
   printf("String In Non Alphabatical order is: ");
    puts(s);
}

Output3

String In Non Alphabetical order is: ONML
