傳遞不同類型的載體爲模板功能

Question

我得到一個編譯器錯誤，說

could not deduce template argument for 'std::vector<T*>&' from 'std::vector<_Ty>'

template <typename T> void foo(vector<T*>& a, int left, int right) 
{ 
    ... 
} 

main() 
{ 
    ... 
    //declare and instantiate 3 vectors 
    vector<int> intVector; 

    foo(intVector, 0, 100); 
    foo(doubleVector, 0, 100); 
    foo(charVector, 0, 100); 
    ... 
} 

Answer 1

int無法比擬T*。

要麼使vector a vector<int*>或使模板採取vector<T>。
