{
not a very elegant way of doing it but it should work
}
program nestedif ;

var
name : array[1 .. 3] of string ;

begin
{
get the three names -- we could us a loop here
}
write ('Enter first name ') ;
readln (name[1]) ;
write ('Enter second name ') ;
readln (name[2]) ;
write ('Enter third name ') ;
readln (name[3]) ;

writeln (name[1]) ;
writeln (name[2]) ;
writeln (name[3]) ;
{
sort and print
}
if (name[1] <= name[2]) and (name[1] <= name[3]) then begin
{
name[1] is first
}
writeln (name[1]) ;
if name[2] <= name[3] then begin
writeln (name[2]) ;
writeln (name[3])
end
else begin
writeln (name[3]) ;
writeln (name[2])
end
end
else if (name[2] <= name[1]) and (name[2] <= name[3]) then begin
{
name[2] is first
}
writeln (name[2]) ;
if name[1] <= name[3] then begin
writeln (name[1]) ;
writeln (name[3])
end
else begin
writeln (name[3]) ;

end

end

name[3] if first
}

writeln (name[1]) ;
