assignment problems: have to submit tomorrow

Two assignment problems.. have to submit tomorrow.. please help..
1. Write a program tht will read in a text from a file
, replace all occurance of the string |"and" by "or|"
. write the modified text onto another file

2. write a program to search for a given word in a
dictionary . the dictionary is a lexicographically
sorted array as character strings. Use binary search
method.

What do you need help with? You'll need to be a bit more specific than just posting your assignment sheet up and hoping someone will do it for you

Hey Mate!. Here's the thing.

1) First of all, if you want to keep it simple, use two pointers (one for each file). As you move throught the text, if the character is not an "A", just copy it to the new file. If the char is an "A", copy it to a Buffer and move on. If doing so, you spell "AND", empty the buffer and write OR on the new file. That is the simplest way to go. You can get both files as parameters with argc and argvec

2) You have to know from advance the binary search method. The procedure is simple (if I understand correctly).

while start < finish {

Pos = (start + finish) / 2



if (value = (strcmp(desiredWord, arrayOfWords(Pos))) == 0){

found = 1;

start = finish + 1

}

else


{

if value > 0

start = Pos

else

finish = Pos

}

}


Check out the value > 0 part, for I don't recall the returned values of strcmp correctly. But the escential idea is that.

Hope it works!!
