Basic application of experimental 12--pointers 2

1. Knowledge points learned in this lesson: (1) string constants use a pair of double quotation marks to enclose a sequence of characters similar to the underlying type. Because the string is a string of characters, all characters in the string constant are stored in memory, similar to the storage of the array.

(2) Introducing character pointers and string processing through the example "code Encryption", highlighting the specificity of string operations and analyzing the causes by contrasting the examples.
(3) input and output of strings: function scanf () and gets () can be used to input strings, while printf () and puts () output strings. They are defined in the system file stdio.h.

2. Problems encountered during the experiment and Solutions: (1) not fully understand the meaning of the topic

(2) Access to information

3. Experience of experiment and summary of this chapter study: This homework feeling very difficult, do not know, or no serious lectures, the next time to continue efforts!
