Question

Test #2:

Find the bug and write the correct version of the program

#include <iostream>

class Utils

{

public:

static double findAverage (int number1, int number2)

return number1 + number2 / 2;

};

}

int main()

std::cout << Utils::findAverage(5, 2); // it should return 3.5

}

Test #3 (optional):

Please find and explain all the errors in the following function. There is at least one of the

following:

1. Compilation error

2. Segmentation fault

3. Performance issue

Flight minFlight(std::vector<Flight> flights)

{

std::sort(flights.begin(), flights.end()); return flights.begin();

}

Also, write the correct version of the program.

Answer 1

Test # :2

#include <iostream>
using namespace std; // This line was missing, for input/ouput declaration
class Utils
{
public:
static double findAverage (double number1, double number2){ // The function should have a body, so use opening  { and  closing } 
return (number1 + number2) / 2; // use brackets to follow order of operations
}
};

int main() { // This opening brace was put in wrong place
std::cout << Utils::findAverage(5, 2); // it should return 3.5
}

Test #: 3

Flight minFlight(std::vector<Flight> flights)
{
    std::sort(flights.begin(), flights.end());
    Flight min = *flights.begin();
    return min;
}

// In your code, the line return flights.begin(); incorrect leading to compilation error
// You did not include the line Flight min = *flights.begin(); to calculate flight minimum which results in segmetation and performance issues
