Code Golf: Connecting the dots

Answer 1

C++ 637

#include 
#include 
#include 
#define S(x)((x)<0?-1:x>0?1:0)
using namespace std;enum{R=100,C=100,D=100};int main(){string s;
int N[D][2],M=0,q=0,p=0,i,j,V,L,a,b;for(i=0;j=0,(i

Indented, and with a few slightly more meaningful names, that looks like:

#include 
#include 
#include 
#define S(x)((x)<0?-1:x>0?1:0)
using namespace std;
enum{R=100,C=100,D=100};
int main(){
    string s;
    int N[D][2],M=0,rs=0,cs=0,i,j,V,L,dr,dc;
    for(i=0;j=0,(i

Despite superficial differences, it's a blatant theft of morotspaj's code.
