11716 why CE ??

[dante]

hi,

I'm getting CE for this code, I don't how to change it, can anyone help ?

Code: Select all

#include<iostream>
#include<cmath>
#include<cstring>
using namespace std;

int main(){
   int n;
   cin>>n;
   getchar();
   for(int i=1; i<=n; i++){
      char ciph[10010], deciph[10010];
      int len, sq;
      gets(ciph);
      len = strlen(ciph);
      sq = sqrt( (float)len );
      if( sq*sq != len ) cout<<"INVALID"<<endl;
      else{
         int dex=0;
         for(int j=0; j<sq; j++ )
            for(int k=0; k<sq; k++, dex++)
               deciph[dex] = ciph[ sq*k + j ];
         deciph[dex]=NULL;
         cout<<deciph<<endl;
      }
   }
   return 0;
}

On my system using g++ I get these compile warnings:

Code: Select all

In function `int main()':
15: warning: assignment to `int' from `float'
15: warning: argument to `int' from `float'
22: warning: assignment to non-pointer type `char' from NULL
22: warning: argument to non-pointer type `char' from NULL

You can see your compile errors by clicking "My Submissions".

tnx.

here is the msg I get from uva.

code.cpp: In function 'int main()':
code.cpp:9:10: error: 'getchar' was not declared in this scope
code.cpp:13:12: error: 'gets' was not declared in this scope
code.cpp:22:16: warning: converting to non-pointer type 'char' from NULL

I can replace "getchar" with "cin.ignore" but what should I use instead of "gets" ?

Oops ! I found out the reason...
