part, my code if far from being complete. My question is, where is my error that is giving me 0instead of 5I feel that it is because of the \n white space within the .txt file. As you can see from the code, I am trying to find all instances of "ATG" within the dna_sample.txt file. Thanks in advance :)
UPDATE: If I remove all of the \n white space, I get the answer I need. unfortunately, I must use the file the way it is and not the way I edited it to be. This means that the white space is screwing things up. Help please!
-1 is the int value of std::string::npos. This is what std::string::find() will return if the string is not found.
That's because you write the first line to genome, then write the second line to genome (first line is lost), then write the third line to genome (second line is lost)... until you write the last line to genome (all other lines have been lost).
You might want to do it this way:
1 2 3 4 5 6
cout<<"Data is: "<< line << endl;//output the data within the file
genome += line; // append the new data to our genome.
