关于模板重载的问题
我的程序是:
#include <iostream>
template <typename T>
void ShowArray(T arr[],int n);
template <typename T>
void ShowArray(T* arr[],int n);
struct debts
{
char name[50];
double amount;
};
int main()
{
using namespace std;
int things[6]={13,31,103,301,310,130};
struct debts mr_E[3]={
{ "Ima Wolfe ",2400.0},
{ "Ura Foxe ",1300.0},
{ "Iby Stout ",1800.0}
};
double *pd[3];
for(int i=0;i <3;i++)
pd[i]=&mr_E[i].amount;
cout < < "Listing Mr.E 's counts of things: \n ";
ShowArray(things,6);
cout < < "Listing Mr.E 's debts: \n ";
ShowArray(pd,3);
return 0;
}
template <typename T>
void ShowArray(T arr[],int n)
{
using namespace std;
cout < < "template A\n ";
for(int i=0;i <n;i++)
cout < <arr[i] < < ' ';
cout < <endl;
}
template <typename T>
void ShowArray(T * arr[],int n)
{
using namespace std;
cout < < "template B\n ";
for(int i=0;i <n;i++)
cout < <*arr[i] < < ' ';
cout < <endl;
}
编译的时候报错:
E:\vc++ 6.0\MSDev98\MyProjects\test3\8_14.cpp(29) : error C2667: 'ShowArray ' : none of 2 overload have a best conversion
E:\vc++ 6.0\MSDev98\MyProjects\test3\8_14.cpp(29) : error C2668: 'ShowArray ' : ambiguous call to overloaded function
Error executing cl.exe.
我用的是vc++6.0,怎么回这样?
[解决办法]
错就错在你不该用vc6
换成vc2005,或者g++ 4
vc对这个那是无能为力的
[解决办法]
vc6对C99支持不够好
而且bug较多
[解决办法]
扔了VC6吧。

楼上已经说了.
