This article is about C language programming (Tan Haoqiang C language third edition) after-class exercises and answers. After learning C language programming, do a few related exercises to review the knowledge points. In the process, the knowledge points that are very abstract and obscure may be combined with a case question, and there may be unexpected results!

3.7
Description : To translate "China" into a password, the password rule is: replace the original letter with the fourth letter after the original letter. (Tan Haoqiang C Language Third Edition, Question 3.7, page 67)
Topic : To translate "China" into a password, the password rule is: replace the original letter with the fourth letter after the original letter. For example, if the fourth letter after the letter "A" is "E", replace "A" with "E". Therefore, "China" should be translated as "Glmre". Please make a program to make the values of the five variables c1, c2,, c3, c4, and c5 be'C','h','i','n','a', After calculation, make c1, c2, c3, c4, and c5 become'G','l','m','r','e' respectively, and output.

4.4
Description : Given a number of characters , and printed out at the appropriate format. (Tan Haoqiang C Language Third Edition, Question 4.4, page 88)
Question : If a = 3, b = 4, c = 5, x = 1.2, y = 2.4, z = -3.6, u = 51274, n = 128765, c1 ='a', c 2 ='b'. The following output formats and want results, write program (including the definition of a variable type and design output). The required output results are as follows:
a= 3 b= 3 c= 5
x=1.200000，y=2.400000，z=-3.600000
x+y= 3.60 y+z=-1.20 z+x=-2.40
u= 51274 n= 128765
c1=‘a’ or 97（ASCII）
c2='b' or 98（ASCII）

Title : programmed, with getchar function reads two characters to c1, c2, and then outputs the two characters and with the putchar function printf function. Consider the following questions:
(1) variable c1, c2 should be defined as a character or integer ? Or both?
(2) What should I do if the ASCII code of c1 and c2 is required to be output ? Use putchar function or printf function?
(3) Can integer variables and character variables replace each other under any circumstances? Such as: char c1, c2; and int c1, c2; are they unconditionally equivalent?
