请看下面的代码
with text_io;
use text_io;
procedure hello is
begin
put_line("hello");
new_line(3);
end hello;
当我在 GPS IDE 中单击“全部构建”时,出现此错误
gnatmake -d -PC:\Users\yohan\firstprogram.gpr
firstprogram.gpr:1:06: literal string expected
firstprogram.gpr:2:01: "end" expected
gnatmake: "C:\Users\yohan\firstprogram.gpr" processing failed
[2013-04-03 13:29:58] process exited with status 4 (elapsed time: 00.47s)
我对 Ada 很陌生,如您所见,这是我的第一个程序。请帮忙。
