IN C LANGUAGE 16.15 Lab 5: filter
Name this program filter. c.
The program takes two command line arguments: the name of an input file and the name of an output file. The program should confirm the input and output files can be opened. If a file cannot be opened, print the error message Cannot open file '' where is the name of the file and return.
fopen() will return 0 if it fails to open a file.
Then, the program will read the file string by string (up to 50 characters in length). If the string consists of only uppercase and lowercase characters, print it.
You can use isalpha(char) declared in ctype. h to check whether a character is a-z or A-Z.
continue and break might be useful.
Don't forget to close your files!

Acomputer has a two-level cache. suppose that 60% of the memory references hit on the first level cache, 35% hit on the second level, and 5% miss. the access times are 5 nsec, 15 nsec, and 60 nsec, respectively, where the times for the level 2 cache and memory start counting at the moment it is known that they are needed (e.g., a level 2 cache access does not even start until the level 1 cache miss occurs). what is the average access time?
