Hi,

You can't use the key word "strcmpi".
It is not allowed under ANSI C/C++.

Good luck~

[hank]

You can use the following code to replace that function.
[c]
#include "string.h"
#include "ctype.h"

int strcmpi(char *a,char *b)
{
int i;
if( strlen(a)>strlen(b) ) return 1;
else if( strlen(a)<strlen(b) ) return -1;
for(i=0;i<strlen(a);i++){
if( toupper(a)>toupper(b) ) return 1;
else if( toupper(a)<toupper(b) ) return -1;
}
return 0;
}[/c]

Good luck~

[Riyad]

thanx hank ,

u helped me a lot . i am successful to remove the compile error after ur suggestion and using u r function . hey but as a matter of regret getting wa for some reason . cant find it why ??
sorry for being my stupid and not to check the function strcmpi () in the ansi c/c++ list.
thanx once again
Bye

thanks 2 LAZ boy.
ur sample input is truely helpful for the problem.
It's like hidden truth in the sample input .

[Lon]

This is my code!!
who can tell me why get runtime error!!!
thanks

#include<stdio.h>

you should really use the code tags

{
int v;
for(v=0;re[j][v]!='\0';v++)
key[j][v]=re[j][v];
}
void main()
{
int time[100],dir[100];

[Minilek]

hm..not quite sure what happened there

but anyway, you do it : )

[Morning]

punctuation marks [SPMamp".,!?&]
the punctuation marks should contain "@#",not "SPMamp"
guess something wrong when the text was translated.

[Lebedenco]

I know it is supposed to be a simple problem but I'm getting WA and I just can't figure out why! I don't like to post code but anyway here it is. The idea is to get rid of any char that is not alpha and then using a stringstream (similar to sscanf) retrieve every single word remaining and compare to the words in the dictionary.

(code removed)

Thanks in advance.

[A1]

There is error in your code so I could not compile your code!
Nobody is going to help you by fixing you code error. I think one should not post their PE code here but when you are in WA - you can post it.

I don't know why it says Compile Error.The code compile well on my VC++6.0 and GCC.Is there anyone who can help me?Thanks !
Here is my code:
#include <iostream.h>

int main()

[misof]

As a rule of thumb, don't mix C, old C++ and new C++ header files. In your case, instead of

Code: Select all

#include <iostream.h>
#include <stdio.h>
#include <string.h>
#include <cctype>

use

Code: Select all

#include <iostream>
#include <cstdio>
#include <cstring>
#include <cctype>
using namespace std;

The last line is important. Some compilers do this automatically, g++ doesn't. The C++ header files (you included cctype) define their symbols and functions in the std namespace. Thus g++ couldn't find the function isalpha() you use in your code -- without the "using namespace std;" you would have to write std::isalpha().

[frankhuhu]

Thanks misof.I have change the head file but still Compile Error!
Any more good suggestions?
