Comparing words in text file line by line

I got a text file with only one word in each line. How can I open and compare each word from this file with required word in a loop?

"I got a text file with only one word in each line. How can I open and compare each word from this file with required word in a loop?"

It's probably best to read the entire file rather than line-by-line. Then you compare each line with your required word. Here's a demo that reads a file named "data.txt" and searches for the requiredWord "sunshine".

% Read in the entire file, keep columnar arrangement
t = strsplit(fileread('data.txt'))'; 
requiredWord = 'sunshine'; 
[hit, lineNumber] = ismember(requiredWord, t); 
% If you don't want case sensitivity: 
% hit = ismember(lower(requiredWord), lower(t)); 

If you must read line-by-line, use fgetl() in a while-loop that loops through the file line by line. This demo stops either when the word was found or the last line was read.

% Read line by line
fid = fopen('data.txt'); 
tline = fgetl(fid); 
hit = false; 
c = 0; %counter
while ischar(tline) && ~hit
    c = c+1; % if you want the row number
    hit = strcmp(requiredWord, tline); % use strcmpi() for case insensitivity
    tline = fgetl(fid); 
end
fclose(fid);

Thank you so much Adam Danz. It worked.
