T max() MyVector should overload the [] operator to allow users toaccesselements by their index (you don't have to overload it to let users change values in the vector by index) MyVector should also overload the + operator, with a const ...
先读一遍《Effective C++》。
Inside the main function, a new vector, vec1_c, is declared and initialized with the elements of the original vector, vec1, using the copy assignment operator. This results in a shallow copy of the original vector, meaning both vectors now share the same underlying elements.Output:...

1、c+中vector的用法(The use of vector in c+)C+s built-in array supports the mechanism of containers, but it does not support the semantics of container abstractions. To solve this problem, we implement such a class ourselves. In standard C+, container vectors (vector) are used. The ...

(3) Look for errant use of the assignment operator instead of the comparison operator:if(x = 10) // Oops! Should be if(x == 10) // may get a compiler warning for this (4) To conserve memory, ensure that you have no memory "leaks". Are you always doing delete[] for every new...
