Consider the following code: Token LexicalAnalyzer: : GetToken()
input . GetChar(c);
switch (c) {
case '=':
input . GetChar(c);
if (c = = '=') {
tmp . token_type = EQEQ;
} else if (c = = ' <') {
tmp . token_type = EQLT; }
else if (c = = '>') {
tmp . token_type = EQGT; } else
tmp . token_type = ERROR;
return tmp;
default:
tmp . token_type = ERROR;
return tmp;
1. In the code, input. GetChar() gets the next character from standard input. If GetToken() is called four times, which of the following inputs will return a token whose type is ERROR?
A.
A. =<
B. ===>
C. <==
D. <=
2. If GetToken() is called four times on input <==<==, how many times is ERROR returned?
a. 0
b. 1
c. 2
d. 3

Write the command that can be used to answer the following questions. (hint: try each out on the system to check your results.) a. find all files on the system that have the word test" as part of their filename. b. search the path variable for the pathname to the awk command. c. find all files in the /usr directory and subdirectories that are larger than 50 kilobytes in size. d. find all files in the /usr directory and subdirectories that are less than 70 kilobytes in size. e. find all files in the / directory and subdirectories that are symbolic links. f. find all files in the /var directory and subdirectories that were accessed less than 60 minutes ago. g. find all files in the /var directory and subdirectories that were accessed less than six days ago. h. find all files in the /home directory and subdirectories that are empty. i. find all files in the /etc directory and subdirectories that are owned by the group bin."
