用C语言做中介信息管理系统时的一个问题

AaronMix 2007-09-19 02:27:14
用C做一个中介信息管理系统,还没把Search功能写好,但主函数都写好了,想先运行下看看是否出错。用的是VC++6。
首先，编译.OBJ时没有Error,但是有Warning.
warning C4013: 'clrscr' undefined; assuming extern returning int
warning C4013: 'textmode' undefined; assuming extern returning int
warning C4013: 'textbackground' undefined; assuming extern returning int
warning C4013: 'window' undefined; assuming extern returning int
warning C4013: 'gotoxy' undefined; assuming extern returning int
warning C4013: 'textcolor' undefined; assuming extern returning int
warning C4013: 'save1' undefined; assuming extern returning int
warning C4013: 'save2' undefined; assuming extern returning int
warning C4716: 'del1' : must return a value
warning C4716: 'del2' : must return a value
warning C4716: 'save1' : must return a value
warning C4716: 'save2' : must return a value
然后组建EXE，在link的时候出现
error LNK2001: unresolved external symbol _gotoxy
error LNK2001: unresolved external symbol _window
error LNK2001: unresolved external symbol _textbackground
error LNK2001: unresolved external symbol _textmode
error LNK2001: unresolved external symbol _clrscr
error LNK2001: unresolved external symbol _textcolor
Debug/ZHONGJIE.exe : fatal error LNK1120: 6 unresolved externals
网上先找过点资料，说是头文件要<conio.h>,但还是出错，希望各大侠帮忙小弟解决下，我先去写search的功能了~~。
最后附上我的源代码~~
#include <stdio.h>
#include <stdlib.h>

把load1和load2的声明放在所有函数最前面,也就是#include之后

谢谢大家.
刚才用turbo c/c++ 3编译了下
在insert applicant 和insert job下针对
head1=load1()和head2=load2()语句出错
说
Type mismatch in redeclaration of 'load1'/'load2'

你是在用BGI库，
这个东西要用BC3.1来编译连接的。

不能用VC6

用TC编译.
VC没有提供clrscr(),gotoxy()这些库函数
