1. How can you force instantiation of a template? Explain with example.
2. What is an algorithm (in terms of STL/C++ standard library)?
3: Is anything wrong with the following code fragment:
T *p = 0;
delete p;

1. make a declaration before the template is really used.
i.e. template class A;
2. a template function work with containers via iterators
3. none

example.

if no other codes between the two lines, then no.
operator delete can handle a null pointer.

example.
1. use static funtion.
2. an algorithm is a function in a predefined template.
3, T is unknow, if T is an array, you need to use delete[]

2, it should be called generic functions.
