Change your my_p() function.
Code: Select all
int my_p(char ch)
{
if((ch>='a'&&ch<='z')||(ch>='A'&&ch<='Z'))
return 0;
else
return 1;
}
Hope it works.

I don't know pascal. But I can say that this problem requires a big array. My array size was 1000000.
Hope it helps.
492 Wrong Answer why ??

Iam getting wrong answer for the 492 question. I have checked most of the
cases I can think of .
<code>
#include <iostream>
#include <vector>
#include <list>
#include <string>
#include <sstream>
#include <stdio.h>
#include <stdlib.h>
using namespace std;
int main ()
{
string x = "";
char ch;
while ((ch = getchar ()) != EOF)
{
if (isalpha (ch))
{
x+= ch;
}
else{
if ( toupper (x[0]) == 'A' ||
toupper (x[0]) == 'E' ||
toupper (x[0]) == 'I' ||
toupper (x[0]) == 'O' ||
toupper (x[0]) == 'U'
)
{
x+= "ay";
}else
{
if (x!="")
{
char c = x[0];
x = x.substr(1,x.size()-1);
x+=c;
x+="ay";
}
}
cout << x ;
cout << ch ;
x = "";
}
}
if (x!= "")
{
if ( toupper (x[0]) == 'A' ||
toupper (x[0]) == 'E' ||
toupper (x[0]) == 'I' ||
toupper (x[0]) == 'O' ||
toupper (x[0]) == 'U'
)
{
x+= "ay";
}else
{
if (x!="")
{
char c = x[0];
x = x.substr(1,x.size()-1);
x+=c;
x+="ay";
}
}
cout << x ;
cout << ch ;
x = "";
}
}
</code>
Can anyone tell me for which case is the program failing??

before checking
toupper(x[0]) == SOMETHING
u should check whether x == "" or not
492-- Why I Get WA ??? Please Help...

Try this input:
Code: Select all
This is the input.
This.is.the.input.
2 spaces separate each word for the first line.
And for the second line, the period '.' separates each word.
Your code will fail for these test cases because you used strtok. You are assuming only 1 space separate each word.
The problem description says:
A "word" is defined as a consecutive sequence of letters (upper and/or lower case)
It does not mean the words are separated by exactly 1 space.
There are test cases in past threads. Just do a search for 492.

Explain a difference
A get AC with this code(492)
#include <stdio.h>
#include <ctype.h>
int alpha(int c)
{
if ((c>='A'&&c<='Z')||(c>='a'&&c<='z')) return 1;
return 0;
}
int main()
{
int c,last,t;
c=getchar();
while (c!=EOF)
{
last=tolower(c);
if (alpha(c)) t=1;
else t=0;
if ((t==1)&&(!((last=='a')||(last=='e')||(last=='i')||(last=='o')||(last=='u')))) {last=c; c=getchar();}
else last=0;
while (alpha(c))
{
putchar(c);
c=getchar();
}
if (last!=0) putchar(last);
if (t==1) {putchar('a');putchar('y');}
if (c!=EOF) {putchar(c); c=getchar();}
}
return 0;
}

And get WA with this:
#include <stdio.h>
#include <string>
#include <ctype.h>
int alpha(int c)
{
if ((c>='A'&&c<='Z')||(c>='a'&&c<='z')) return 1;
return 0;
}
int main()
{
int c,last;
std::string str;
c=getchar();
while (c!=EOF)
{
str="";
last=tolower(c);
if (alpha(c)&&(!((last=='a')||(last=='e')||(last=='i')||(last=='o')||(last=='u')))) {last=c; c=getchar();}
else last=0;
while (alpha(c))
{
str+=(char)c;
c=getchar();
}
if (last!=0) str+=(char)last;
if (str!="") str+="ay";
printf("%s",str.data());
if (c!=EOF) {putchar(c); c=getchar();}
}
return 0;
}

Why on my computer (Visual Studio 2005) this code work?

I don't know. Possibly, VS2005 has a different implementation of
strings than GCC. The STL documentation states:
STL documentation wrote:const charT* data() const: Returns a pointer to an array of characters, not necessarily null-terminated, representing the string's contents. data() is permitted, but not required, to be identical to c_str(). The first size() characters of that array are guaranteed to be identical to the characters in *this. The return value of data() is never a null pointer, even if size() is zero.
Have you already tried to submit that code with
str.data() exchanged by
str.c_str()? Has it helped?

Thanks for the help.
It has really helped.
Anybody known other different between VS 2005 and GCC?
I like VS 2005. But I have many error because In VS has a different implementation than GCC.

I don't know, I've never used VS. It may be helpful for you to compile your solutions also by GCC before submiting. There is a version of GCC for MS windows, too. Look at
http://www.mingw.org/.
