这是源代码：
// Fig. 4.19: fig04_19.cpp
// Linear search of an array
#include <iostream.h>

int linearSearch(const int[],int,int);

int main()
{
const int arraySize = 100;
int a[arraySize],searchKey,element;

for(int x=0;x<arraySize;x++) // create some data
a[x]=2*x;

cout<<"Enter integer search key:"<<endl;
cin>>searchKey;
element=linearSearch(a,searchKey,arraySize);

if(element!=-1)
cout<<"Found value in element "<<element<<endl;
else
cout<<"Value not found"<<endl;

return 0;
}

int linearsearch( const int arraay[], int key, int sizeofArray )
{
for(int n=0;n<sizeofArray;n++)
if(arraay[n]==key)
return n;

return -1;
}
报错信息：error LNK2001: unresolved external symbol "int __cdecl linearSearch(int const * const,int,int)" (?linearSearch@@YAHQBHHH@Z)
//Debug/fig_04_19.exe : fatal error LNK1120: 1 unresolved externals
请问一下高手，怎么解决这个问题，还有报错的原因是什么？

int linearSearch(const int[],int,int); //S大写

int main()
{
const int arraySize = 100;
int a[arraySize],searchKey,element;

for(int x=0;x <arraySize;x++) // create some data
a[x]=2*x;

cout < <"Enter integer search key:" < <endl;
cin>>searchKey;
element=linearSearch(a,searchKey,arraySize);

if(element!=-1)
cout < <"Found value in element " < <element < <endl;
else
cout < <"Value not found" < <endl;

return 0;
}

int linearsearch( const int arraay[], int key, int sizeofArray ) //S小写
{
for(int n=0;n <sizeofArray;n++)
if(arraay[n]==key)
return n;

return -1;
}

混C/C++版的个个都可以成为高手，不就是个大小写转换么，还只是一个字母。

lz可以将S改为s，也可以将s改为S :-D
