OJ Board

Did you really test your program with the sample I/O given?

i dont no what the err is actually,it gives right ans on my dev-c++;
plz help me.

since you are using ch = getchar(),
it implies you are getting a '\n' at the end of each line.

('\n' - 7) != '\n' and hence the problem.

add this line to your code,
if( ch == '\n' ) putchar('\n');
else {
your code.
}

Maybe there is an error in array size

I got AC with that

you must take the character into ascii form. then subtract 7.

Hi,
this is my mail. Anyone plzzzz help me!


code for 494 :
#include<stdio.h>
#include<ctype.h>
void main()
{
int word,i;
char str[10000];
while(1)
{
word=0;
gets(str);
if(str[0]!='\0')
{
if(isalpha(str[0]))
word++;
for(i=0;str!='\0';i++)
{
if(str==' '||str=='\t')
if(isalpha(str[i+1]))
word++;

}
}
printf("%d\n",word);
}
}

Idonno why i am getting Output Limit Exceeded!
plz anyone,do let me know!!!


458 is an easy one but i am getting TLE!(why??)
code for 458:#include<stdio.h>
void main()
{
char str[100000];
int i;
while(1)
{
gets(str);
for(i=0;str!='\0';i++)
{
str=str-7;
printf("%c",str);
}
}
}

please someone HELP me! i just got stuck'n here...
[/u]

There is no breaking condition in your "while" loop ...
try some thing like
while(1) defines an infinite loop ... while(gets(str)) will break when it reaches End of Input File

Both problem there are no breaking condition!!!

494 :
Read the problem statement carefully.

#include<stdio.h>
#include<stdlib.h>
int main()
{
char c;
char *Output;
int i=0,j;

printf("please input words\t");

Output=(char*)malloc(100*sizeof(char));

while((c=getchar())!='\n')
{
Output=c-'J'+'C';
i++;
}

for(j=0;j<i;j++)
printf("%c",Output[j]);

printf("\n");

free(Output);

return 0;
}

your code ran in my computer nicely

But if you you want to get AC in 458 you have modify your code

remove this line

printf("please input words\t");

and try to scan input until end of file (EOF)

this may help you

Best of luck

#include <iostream>
using namespace std;
int main()
{
char ch;
cin.get(ch);
while (ch != '\0')
{
if (ch == 10)
cout << ch;
else
cout << (static_cast<char>(ch-7));

cin.get(ch);
}
cout << '\n';
return 0;
}
my code works fine and im getting the correct output, except when i submit the code, im getting output limit exceeded...i dont understand why?!

you should stop reading data when it get end of file (EOF).

Regards.I got TLE for #458 but couldn't find the bug(s).Can anyboby help?
here is my code:

#include <iostream>
using namespace std;

int main()
{
char ch;
while((ch=cin.get())!=EOF)
{
if(ch==10)
cout<<"."<<endl;
else
{
ch-=7;
cout<<ch;
}
}
return 0;
}

Use getchar() to read, from cin it is not reading the EOF(though it works fine on my compiler). This is giving you TLE.

Then remove the extra "." you are printing.

And don't open a new thread if there already exists one.
