Thread: help writting code

I have this code to write and does not know how....please help

Your program takes input from a file it is said to be reading from the file and sends output to a file it is said to be writing to the file.
The input file may contain any kind of English text. That means,
anything, but no "funny characters" like Tilde (~) that are not normally
used in English text. However,! ? % $ , . ; : "' () - & and numbers may occur.
Your program should
= Throw away all special characters.
= Extract all words.
= Make all words lower case only.
= Sort all words alphabetically.
= Remove duplicates.
= Send the sorted words to the output file.


thank you

homework 101 is at a different site. Here, we like to help those who help themselves. Post code with problems you are having and you are likely to get a better response.

ohh really..I didn't know that...can you tell me how to write it then I will post the problems.........

declare a struct called node to hold a string (ie word) a counter to keep track of how many times the word appears in the file and a pointer to the next node

declare a list class that does an insertion sort using strcmp on the string in the node to sort and a print function to display the string and the counter

The insertion sort will be passed a string. It will then search the string to see if the passed string is present in the list. If it isn't it will declare a new node using dynamic memory, assign the passed string to the node string using strcpy, assign 1 to the counter, and assign NULL to the pointer. It will then insert the node in the appropriate position. If the passed string is present it will increment the node counter holding the string.


declare a char to hold each char as it is read in

declare a buffer of 30 char to hold each word as it is being built
assign tilde to first element of buffer

declare int to act as buffer index and initialize to zero

declare ifstream and open file for reading

verify file opened successfully

read in first char outside of loop

create a loop stopping when you find EOF

in loop evaluate each char into three cases:
a) if isalpha(input char)--tolower(input char)--assign input char to buffer if buffer index < 30
b) if isspace(input char)--if buffer[0] not tilde--add null terminating char to buffer---send buffer to list.insertionSort--assign tilde to buffe[0]--assign 0 to fbuffer index
c) if not letter or space ignore input char.

then read in next char before going back to top of loop

print list after file reading completed.
