Question

I want to eliminate the junk that I’m getting on the vector<int> synsAux below. It should print:

1  7 7 1 

I’m getting an extra 2 before the first and third digit, why? Is this 2 an ascii value for the blank space or something? How do I avoid its reading?

This is the dictionary file needed to run the program:

dictionary.txt 1 cute 2 hello 3 ugly 4 easy 5 difficult 6 tired 7 beautiful synonyms 1 7 7 1 antonyms 1 3 3 1 7 4 5 5 4 7 3

You’re printing the twos here:

cout<<synsAux.size();
