compile error

[abilendur]

can anybody suggest what is wrong with this, it compiles nicely on my home machine g++ with cygwin and on programmingchallenges.com but here I get a compile error (the problem is contest scoreboard)

Code: Select all

#include <iostream>
#include <ctime>
#include <cstdlib>

    int tried[200][10]; //contestants, problem ::TRIED nr

Code: Select all

   srand( (unsigned)time( NULL ) ); 

to use srand(), you need to include <time.h>
btw why you need that function..?

[abilendur]

Left it in from old times.
Still doesn't compile here any more bugs??

[Krzysztof Duleba]

Actually srand comes from <cstdlib>.

You need to include <ctime> for time and clock and <cstdlib> for srand and qsort. Anyway, qsort is old and slow and just plain ugly, use std::sort instead.

[abilendur]

fixed include files
qsort looks fine to me, dont have to mess with redefining any operators

still junk

[abilendur]

just got Solved from both, beats me why the sucker wouldnt compile

clock()/(double)CLK_TCK seamed to cause some problems tough
