Students in Wanliu has to either take a bus or ride a bike to go to school. Due to the bad traffic in Beijing, many students choose to ride a bike. We may assume this all the

proceed from where you left off to print getting ready to say bye ..., and then call the function bye. Add a function bye memory block at the top of the stack, then print OK bye!, and return from this function. Now again back to the function greet, because there is no action down, it is returned directly from the function greet. This stack is used to store variables of multiple functions, called call stacks. 3.1: The available information is The function greet is called a

Analysis: The first consideration of the problem when the brain short-circuit, always the length of 2, 3, 4 of the substring of the case alone, and then only to think that the length of the 2 is the same as the substring. In addition, for the member function of the string type substr () parameter is somewhat forgotten, the function's two parameters indicate the starting position of the substring and the length of the substring respectively. The implementation code is as follows:[CPP]View Plainc

cause any problems, that is, there is no reason to prohibit such assignment. In fact, the compiler does allow this assignment, which is where unique_ptr is smarter.in summary, when the program attempts to assign a unique_ptr to another, if the source unique_ptr is a temporary rvalue, the compiler allows this, and if the source unique_ptr will exist for some time, the compiler will disallow this , such as:Unique_ptr#1留下悬挂的unique_ptr (PU1), which can cause harm. and # # does not leave the danglin
