In c language learning, the memory management part of the knowledge of the master is particularly important. The previous malloc () and free () two functions in C are very poorly understood, only know how to use it-that is malloc and then free is

1. Implicit conversion     C is implicitly converted in the following four situations: 1. In arithmetic expressions, a low type can be converted to a high type. 2. In an assignment expression, the value of the right expression is automatically
