有时在Delphi使用指针类型的数据,总是提示如下: [Warning] FGroupFeedBack.pas(796): Unsafe typecast of 'Pointer' to 'TObject' [Warning] FGroupFeedBack.pas(696): Unsafe type 'PChar' 比较烦,虽说不是bug,但是看着不爽。做程序最好做到没有waring和hints. ...
most languages support at least an understanding of the difference between "integer" types and "string" types. This information allows error-checking by thecompilerthat can reduce many silly programmererrors, like attempting to treat a string as an integer or vice versa: errors that wouldn't be...
