    Write a function checkeven that take in two parameters: an array call numarray containing integers and its size. The function should return the number of even integers in the array. You should initialise some values into the array numarray. Good luck guys!

    Hope is the first step on the road to disappointment.

    That's a pretty lame attempt. We've seen just about every trick in the book to get other people to do your homework, and this one doesn't even rank in the top ten. It's not even as amusing as the people who pretend to be teachers. I can't give you a very good grade for this.

    Your grade:
    F
    My best code is written with the delete key.

    Even if this was actually a challenge you were trying to give us. Most of the people here are programmers for a living. Do you really think this program is a challenge for them? This isn't a challenge for a first year Computer Science student. Please, take this sad attempt for a post to another forum.

    Another translation - post wacky obfuscated answers which the OP can't possibly hand in as their homework assignment, but which are fun non the less

    Code:
    #include <stdio.h>
    
    int checkeven ( int *numarray, int size ) {
      int j, p = 0, m = ~(~0<<1), c = size;
      while ( p < size ) {
        unsigned int v = 0, w, x;
        for ( j = 0 ; j < 32 && p < size ; j++, p++ ) {
          v ^= ( *numarray++ & m ) << j;
        }
        w = v - ((v >> 1) & 0x55555555);
        x = (w & 0x33333333) + ((w >> 2) & 0x33333333);
        c -= ((((x + (x >> 4)) & 0xF0F0F0F) * 0x1010101) >> 24);
      }
      return c;
    }
    
    int main ( ) {
      int i, test[100];
      for ( i = 0 ; i < 100 ; i++ ) test[i] = i;
      printf( &"%d even numbers found\n"[0], checkeven(test,i) );
      for ( i = 0 ; i < 100 ; i++ ) test[i] = i|1;
      printf( &0["%d even numbers found\n"], checkeven(test,i) );
      for ( i = 0 ; i < 100 ; i++ ) test[i] = i*2;
      printf( "%d even numbers found\n", checkeven(test,i) );
      return 0;
    }

    Haha...

    "Ehhh... I don't really think that's a good idea, teacher."

    "Nonsense, with your knowledge of programming at your age? You should ace that course easily."

    Salem was not banned - otherwise how would he be using his account?

    Nice to see you posting though Salem.
