Need help fixing this code:

Trying to read from an input file like this

2.5 0.2 -25.6 -25.60 2.5 2.5 +16.25 12.6.7 2.5 .5 5. 0.7 16.25 -25.6 2.5

But its giving me an output of

List of real values and their number of occurrences: +16.25: 1 -25.6: 2 -25.60: 1 0.2: 1 0.7: 1 16.25: 1 2.5: 5

But -25.6 should have a value of 3 and 16.25 should have a value of 2

bool isReal(const string& word)

{ if (word.size() < 3) { return false; }

int i = 0, dots = 0;

if (word[0] == '+' || word[0] == '-') { if (word.size() == 1) { return false; } ++i; }

for (; i < word.size(); ++i) { if (!isdigit(word[i])) { if (word[i] == '.') { ++dots;

if (dots > 1) { return false; } } else { return false; } } } return dots == 1; }

vector realWords;

map realCount;

string line;

while (getline(in, line)) { string word; istringstream iss(line);

while (iss >> word)

{

if (isReal(word))

{ realWords.push_back(word); ++realCount[word]; } }

}

cout << " List of real values and their number of occurrences: ";

for (const auto& item : realc) {

cout << item.first << ": " << item.second << endl; }
