运行多个源文件（简单）

源程序：

Helloworld:

#include "print.h"int main(void){printHello();return 0;}

print.c:

#include "print.h"void printHello(){print("hello word!\n");}

print.h:

#include "stdio.h" extern void printHello(void);

1、使用Visual C++6.0创建空的工程

2、在fileview窗口分别添加3个文件

3、编译报错

print.obj : error LNK2001: unresolved external symbol _printDebug/helloword.exe : fatal error LNK1120: 1 unresolved externals

定位print.c文件的发现printf写错为print，修改后编译通过

Deleting intermediate files and output files for project 'helloword - Win32 Debug'.--------------------Configuration: helloword - Win32 Debug--------------------Compiling...helloword.cprint.cLinking...helloword.exe - 0 error(s), 0 warning(s)

运行成功
