This header file

CodePudding user response:

Strcpy is c function, c functions in c + + using the corresponding c header file is the beginning of the
. For example, the original stdio h in c + + using the standard usage
Not # include & lt; Stdio. H>
But # include

Compiler low-level, no default contain the function

CodePudding user response:

What no default contain the
Must have a clear contains is possible, in other mainstream compiler also
Strcpy is c functions, c + + inside with a c function, must have a clear inclusion relation

Even the c language, you only # include Also use the strcpy function

CodePudding user response:

Add a header files, # include
C + + non-technical area with 400 points

CodePudding user response:

See error description, this is the system API, said can't find that is not include, error description can solve many problems, you see
