I've got problem with printing out double type.
int xx=1, yy=1, zz=0, i=46;
float xxx=1, yyy=1, zzz=0;
long double x=1, y=1, z=0;
for(int i = 0;i<r;i++)
{ zz=xx;
zzz=xxx;
z=x;
xxx=xxx+yyy;
xx=xx+yy;
x=x+y;
yyy=zzz;
yy=zz;
y=z;
cout<<i+3<<"---------"<<x<<"----"<<xx<<"----"<<xxx<<"\n"; /*fibonacci*/
}
i use float, int, and double to see what's the cause of the problem.
program prints out this(if (i==46))
