working with textfiles in c++

[sajenia]

a text file contains a number of English sentences and each line in the file holds just one sentence. consider a class which will perform the following:
1 reads these sentences and stores them in an array
2 displays the sentences from the array created in 1
3 sorts the sentences into alphabetical order
4 given a word, determines how many times the given word occurs in all the sentences.

please, any one out there with an idea!

Do you have written any code to start with? I don't think there will be too many people solving your assignments for you ... but there will be people willing to help if you come up with concrete problems or questions, I guess :-)

Pseudocode for #1

open text file
// it would be nice if it told you how many lines to make it
while(not end of file)
{
  str = get next line
  if(array full)
    make a bigger array
  insert str into next open spot in array
  increment index for next open
}
close the text file

Pseudocode for #2

for(int i = 0; i < NEXT_OPEN_ENTRY; i++)
{
  output each sentence
}

Pseudocode for #3

for(each array entry)
{
  select a default "minimum" string.
  for(each unsorted array entry)
  {
    compare the minimum string to each entry
    if each entry is alphabetically less than the current minimum
      then it's your new minimum
  }
  swap the minimum string with the default
}

You still have to figure out how to compare two strings, which isn't too bad. There should be a method of some sort to do it for you.

Pseudocode for #4

read in the word to search for
initialize a counter to zero
for(each string)
{
  while(not end of string)
  {
    while(not the end of the string) 
    {
      compare it with pattern
      if there isn't a match
       then fast forward to non-alphabetic characters
    }
    if a complete match
      increment the counter
    while(non-alphabetic characters)
      fast forward to alphabetic characters
}
