The role of the program's debugging: To track the CPU execution code steps to monitor how variable values change during program execution Do-while and while in real development, do-while is less useful because even if the loop is executed at least

1. Macro Replace commandWhen the compiler encounters an identifier defined by the macro substitution command, replace the identifier with the string that follows it. the symbolic constants are defined in this way. the form is as follows:　　#define

For some time did not write some about the data structure of the program, just the introduction of the algorithm of the course to learn red and black trees, the sense of data structures are almost forgotten, but also to test, and then take to review.
