There are some bugs in the program and I can't seem to find anymore on my own, I was hoping someone could help asap. The functions I believe that have bugs are read_people and count_tsv_file_entries.

/*

* This program should compute the average and maximum age of all of the

* people in a TSV data file whose lines each look like this:

*

* LAST_NAME FIRST_NAME ID AGE

*

* Once compiled, you can run this program like so:

* ./debugging-problem-3 data.tsv

*/

std::string last_name;

std::string first_name;

std::string id;

int age;

};

/*

* This function counts and returns the number of entries in a TSV file. The

* number of entries is counted as the number of non-empty lines.

* Hint: there shouldn't be any bugs in this function.

infile.seekg(0);

do {

getline(infile, line);

if (line.length() > 0) {

count++;

}

} while (!infile.eof());

// Make sure the file's ready to read with the cursor at the beginning.

infile.clear();

infile.seekg(0);

return count;
