I got WA with my code.. i dont know why.....

the output is ok , i think. But, i think.. the only problem with to scan a number frm the user or.. for the newline at the end of each output.

In the previous post of this board I found ,, to use scanf("%s",input) .... istead of gets(input),, but why??????????

if i use gets then, what is the problem? and if i use scanf then how can make a new line at the end of each output..

I hope, u'll try to help me.

I don't think you can use scanf("%s") here since I'm sure "%s" format ignores white-space ...

My slow but AC-ed Java program reads the input one character at a time and maintains a simple state throughout the runtime.

Thanx so much for ur help. now I m using gets() function... but still wrong answer...

can u tell me some critical input and output?????


c ya ....

[Sajid]

To turuthok,

As for Inforation, u can also use scanf() function as like the following
[c]
while(scanf("%s%c",a,&ch)==2)
.
.
.
.
printf("%s%c",a,ch);[/c]

get it??


Can anyone tell me the critical inputs for this problem???

[turuthok]

Hello Sajid, ... I see ... I never used scanf("%s%c", ...) function like you described ... Will it work if I have an input like this: "abcde fghij" ?

I'm sure it's a little bit confusing coding it using while(scanf("%s%c", ...) == 2) ... Or I'm just too skeptical about that ...

I didn't try your method though ... I should.

Oops, I didn't realize multiple blanks will be truncated ... sorry.
Sajid, the input I mentioned above should be:

Code: Select all

abcde    fghij

-turuthok-
[/code]

[Sajid]

Hello turuthok,

i failed to describe it,,

i meant, instead of this code:[c]while(gets(a))
{
...
...
.....printf("%c",a[i]);
}
printf("\n");
[/c]

we can also use this...[c]while(scanf("%s%c",a,&ch)==2)
{
...
...
...
.....prinft("%c",a[i]);
}
printf("%c",&ch);[/c]

is it clear now???

[turuthok]

Sajid, forgive me ... but I still cannot see how you handle multiple spaces between words using your method of "%s%c" stuff ...

If it works, ... I'm happy for you

Regards,

[Sajid]

turuthok, look ...

[c]while(scanf("%s%c",a,&ch)==2)
{

}
[/c]

here, the single word is stroed in a[] and the next non-alphabet(digit, space, newline etc.) is stored in ch.
and u can do the loop word by word and after completing each loop, jst print the ch variable.. which stored a non-alphabetic chanracter..
and that's it... It works in my program.It's cute technic, isn't it? :wink:

But my program still WA.......................

[Sajid]

I think, u still cant get..

ok, lets compare the following two almost the same programs.

Using gets()...

[c]char a[100];
int i;
while(gets(a))
{
for(i=0;a[i];i++) printf("%c",a[i]);
printf("\n");
}[/c]

Using scanf()...

[c]char a[100],ch;
int i;
while(scanf("%s%c",a,&ch)==2)
{
for(i=0;a[i];i++) printf("%c",a[i]);
printf("%c",ch);
}[/c]

Get it now??? :wink:

To Sajid,
your code

Code: Select all

while(scanf("%s%c",a,&ch)==2)
{
 
}


it has a bug.....since scanf ignores white spaces....your module wont stop until it reached end of file.
Meanwhile, gets function stops when it encounters '\n' or carriage return '\r'. So....your code cannot get one line at a time. Ex :

Input :
What if the input is more than one line?
Like this sample

Using your module.... string a will contain "sample".
But using gets function, a contain "What if the input is more than one line?"
Then....the program starts to process the string to get the proper output
before gets another line.

Hope i'm right,
Nick

[Sajid]

To Nick,
Yes.. i m so sorry that my code has some bugs which i overlooked...

thanx nick.. :wink:

[Sajid]

Sajid, the input I mentioned above should be:

Code: Select all

abcde    fghij

-turuthok-

Turuthok,sorry, my code will not work with the above input..
sorry for that....

[turuthok]

Sajid, don't worry about it ...

I hope you'll get this problem AC-ed soon ...

[Sajid]

at last i got AC ... :D

thanx to all.. specially Turuthok.

c ya ... :wink:
