You can't use some variable names in global namespace when 'using namespace std' is used like next, prev, y1 ... etc

To get around it some people use #define with random name like

#define next lolXD

    According to you,when 'using namespace std'is used,we can't use y1,yes? But why I can use y1 successfully without #define like this: using namespace std; int ne[5][2]={{0,0},{1,0},{-1,0},{0,1},{0,-1}}; int a[41][41],n,m,best; void search(int x) { int i,j,f,k,xx,yy,x1,x2,y1,y2; vector<pair<int,int> >tmp;

      Try this in global namespace:

      long y1;

      The reason is that y1 is already declared in global namespace, it's safe when used locally
