Word-Recognition

For this assignment, you will write a C++ program called hw1 that will read from standard input, recognize words, and display some statistics of questionable value about the

input. It will display the words found, the number of words encountered, and the range of word lengths. If no words are encountered, display an error message, and nothing else.

The input will be any number of lines, containing words. A word is defined as a series of consecutive non-whitespace characters, separated by whitespace. However, parentheses,

(and ), are always separate single-character words, no matter where they appear. Whitespace is defined as any of the six characters " \f\n\r\t\v", or, equivalently, what

isspace() says it is.

A make file is provided for this Word Recognition code

% cat CMakeLists.txt cmake_minimum_required(VERSION 3.11) project(hw1)

Are we in the wrong directory?

if(CMAKE_SOURCE_DIR MATCHES "[Hh]Ww$") if(PROJECT_NAME MATCHES "[^${CMAKE_MATCH_1}]$") message(FATAL_ERROR "Building ${PROJECT_NAME} in ${CMAKE_SOURCE_DIR}") endif() endif()

Using -Wall is required:

add_compile_options(-Wall)

These compile flags are highly recommended, but not required:

add_compile_options(-Wextra -Wpedantic)

Optional super-strict mode:

add_compile_options(-fmessage-length=80 -fno-diagnostics-show-option -fstack-protector-all -g -O3 -std=c++17 -Walloc-zero -Walloca -Wctor-dtor-privacy -Wduplicated-cond -Wduplicated-branches -Werror -Wextra-semi -Wfatal-errors -Winit-self -Wlogical-op -Wold-style-cast -Wshadow -Wunused-const-variable=1 -Wzero-as-null-pointer-constant)

add_compile_options must be BEFORE add_executable.

Create the executable from the source file main.cc:

add_executable(${PROJECT_NAME} main.cc)

Create a tar file every time:

add_custom_target(${PROJECT_NAME}.tar ALL COMMAND tar -cf ${PROJECT_NAME}.tar *.cc CMakeLists.txt)
