shift string1 by 3 places right.

Former Member — Wed, 03 Aug 2005 16:47:49 GMT

code ->

data: string1(10) type c value 'abcdefghij',
      string2 like string1.

write:  / 'Before Manipulations : ',
        / 'string1 = ',string1,
        / 'string2 = ',string2.

string2 = string1.
shift string1.

write : / 'after one shift first letter is gone :-) (leftShift)',
          ' ', string1.

write : / 'after the shift operation there is a permanent change in',
          'the field value of string1'.
shift string1 by 3 places right.

write : / 'after shifting 3 places on the right-', string1,
        / 'DOUBT - only ij has gone, but hij should have gone right ?'.
        


write : / 'string2 also has same as string1 had initially-', string2.

shift string2 by 3 places right.

write : / 'after shifting 3 places on the right-', string2.

Doubt has been marked in the code itself. This is my first post. Please do explain me concept , in the above code,if i am wrong.

To answer you question, no because a space was the third character.

After your initial shift, "A" has been removed, which has added a space to the end of the 10 chanacter field. Then shifting right 3 places would get rid of the space, then the "J", then the "I".

If this answer was helpful, please remember to award points accordingly. Thanks.

Hi,

it is right that only ij is gone. Please consider the following:

Initially:

string1 = 'abcdefghj'

after shift string1:

string1 = 'bcdefghj ' (with trailing space)

after shift string1 by 3 places right:

string1 = ' bcdefg' (deletes ij and the space character)

It works in STRING2 because you never did an initial shift to the left.

If you did want this to work in the string... you would have to find out the length of the string and then shift on that offset.

data: stlen type i.

shift string2.

stlen = strlen( string2 ).

shift string2+0(stlen) by 3 places right.
