this Mastery might sound too     complicated but in fact it is too    easy to regard this mastery is known in Spanish as conditional nested , and no forces have to be an if as it is not the only type of conditional exists, nested conditional may be of different types such as:

if / else
for
while
switch
do
which can be nested ( put inside other ) as often as desired. for instance:

using namespace std;

int main(){

int uno;

cout

cin>>uno;

if (uno!=0){

if(uno

cout

}

else

{

cout

}

}

else

{

cout

}

return 0;

}
