hi Lars and thx for help. I fix a little the first problem, now I paste a
verion in english whit coment because i´m lost here.
the example is the same only this is in english for your compresion of my
problem.
--------------------------------------------------
code
-------------------------------------------------
import std.stdio;
import std.string;
import std.c.stdio;
void main()
{
string _name, _lastname, _response;
int _age, _year, _birth;
_year = 2009;
writef ("Name: ");
_name = readln().chomp;
writef ("Lastname: ");
_lastname = readln().chomp;
writefln ("Hello %s ", _name, _lastname ); /* here is my first
problem, dont show me the last name or show me in
two
lines ( this fix whit .chomp ) */
writefln ("Year of birth: ");
scanf ("%d", & _birth);
_age = _year - _birth;
writefln ("Your age is %d? \t YES \t NO", _age ); /* here is my second
problem, can´t into the response and program*/
_response = readln(); /* show me
else line always */
if ( chomp(_response) == "yes")
writefln ("thank you %s", _name );
else
writefln ("Sorry %s you have %d", _name, _age - 1 ); /* this line
always show me because can´t validate _response */
}
