Hello Jeffrey,
First of all say thank you for you help. I got it, and I wrote a
program for show you:
with Ada.Text_Io; use Ada.Text_Io;
with Ada.Integer_Text_IO; use Ada.Integer_Text_IO;
procedure Read_String_func_1 is
begin
Put ("Type a String: ");
declare
Cadena : Constant String := Get_Line;
begin
Put("You typed: " & Cadena);
end;
New_Line;
Put("Type a Integer: ");
declare
Input : Constant String := Get_Line;
Num : Natural;
begin
Num := Natural'Value(Input);
Put ("You typed :" );
Put(Num, 6);
New_Line;
Put("Converted with Natural'Image is: " & Natural'Image(Num));
end;
end Read_String_Func_1;
