Why are you using int x as lambda argument instead of double or auto?

Hi,

As per your return condition check. its correct only, As per current code you have used x variable as int so its considering round values
return x > 125.00
You are returning greater than > 125.00, so it will consider below one as out put and count will be 5 only.
132.7,
160.4,
150.3,
144.9,
170.5,
If you want as per your expectation then you should change variable type int to double in your lamda,
double main() {
  vector heights = {
    100.3,
    120.8,
    132.7,
    160.4,
    150.3,
    144.9,
    170.5,
    125.6
  };
  auto myLambda = count_if(heights.begin(), heights.end(), [](double x) {
    return x > 125.00;
  });
  cout << "The number of participants will be: " << myLambda;
  return 0;
}

I am not a C++ expert but looking at your code, it seems you are counting values which are greater than 125.00
and below are the values which are greater than 125.00
132.7,
160.4,
150.3,
144.9,
170.5,
Note the decimal point
