Speed of reading

Write a program in C where you will test and compare the speed of sequential reading of a collection by calling function read versus calling mmap. We are interest in how speed of reading depends on the size of the collection and the size of the read call memory. Create a histZ_Marks program that will compute and print a histogram of ASCII collection of characters. In each file count the number of times each letter is repeated. It receives the name of the collection and the flag via the command line: -t <reading type> The read type can be mmap or read. The type selected specifies the function that will be used to read the collection. -b <cache size> The size of byte cache used when reading with the read function. In Mmap has no functionality. Call example: $ echo hello world > [login to view URL] $ ./histZ_Marks -b 10 -t read [login to view URL] d - 1 e - 1 h - 1 l - 3 o - 2 r - 1 w - 1 $ echo aa bc ddd ef > [login to view URL] $ ./histZ_Marks -b 10 -t mmap [login to view URL] a - 2 b - 1 c - 1 d - 3 e - 1 f - 1 Then print a histogram on the standard output. You can measure runtime with the time command.
