How many recursive calls are made to the function NumSeries()?

1)

#include  using namespace std; int NumSeries(int num) { if (num == 1) cout << num << " "; else { NumSeries(num / 2); cout << num << " "; } } int main() { NumSeries(5); return 0; }

Which statement uses buffer manipulators to immediately display the following on the screen? Good morning

Group of answer choices

The following code generates an error. Why?

#include  #include  using namespace std; int main() { ofstreamoutFS; if (!outFS.is_open()) { cout << "Could not open file myfile.txt." << endl; return 1; } outFS << "Hello" << endl; outFS << "1 2 3" << endl; outFS.close(); return 0; } 

Group of answer choices

outFS.close(); is not used correctly

The file 'myfile.txt' has not been opened

The code is missing a header

Data cannot be directly fed into ofstream using outFS <<

Which line in the below code causes an error?

#include  #include  using namespace std; int main() { vector idNums(5); idNums.at(1) = 60; idNums.at(2) = 70; idNums.at(3) = 82; idNums.at(4) = 90; idNums.at(5) = 92; cout << "Size: " << idNums.size() << endl; idNums.push_back(2); cout << "New size: " << idNums.size() << endl; return 0; } 

Group of answer choices

cout << "Size: " << idNums.size() << endl; 

cout << "New size: " << idNums.size() << endl; 

return 0; 

idNums.at(5) = 92;

6)

Which XXX statement correctly assigns the data member runTime with the value of the argument t?

#include  using namespace std; class Duration { private: int runTime; public: void setTime (int t) { XXX } void print() { cout << "x = " << runTime << endl; } }; int main() { Duration set1; int t = 11; set1.setTime(t); set1.print(); return 0; }

this->runTime = t;

this->t = runTime;

runTime-> t;

this.runTime = t;
