 if (!(j >= 50&&j<=0))
   cout<< j<<endl;

one thing,
return 0 from main not 'o' (not o)
your code will work

try this

j = rand()%50;

and replace your condition

if (!(j >= 50&&j<=0))
cout<< j<<endl; 
else
cout<<"out of range"<<endl;

and only print the j
what is does ? requires minute mathematics.

why did you put a return in the middle of main() ? Lines 12-19 will never get executed because of that unconditional return on line 11. Just delete line 11 and the reset will be executed.
