Answer 6

"You initialize int size to 10 and get Segmentation Fault in this line: distance[size]=discalc(cityX[i],cityX[j],cityY [i],cityY[j]);
thus your program crashes before producing output. So change
int size(10); to
int size = 0;
or int size(0); if you really want to use that fancy int constructor."
thanks
