Since you wrote a program to compare the portion of drivers who were on the phone. The statements are true are option 2, 3, 4 and 5:
2. You could modify the program to allow the user to enter the data.
3. A different set of observations might result in a larger portion of male drivers being on the phone.
4. Even when confident that the mathematical calculations are correct, you still need to be careful about how you interpret the results.
5. It is important to test your program with a small enough set of data that you can know what the result should be.
<h3>What use does a driver program serve?</h3>
A computer software known as a driver, sometimes known as a device driver, that serves as a bridge between the operating system and a device such a disk drive, or keyboard. The device's collection of specific commands must be thoroughly understood by the driver.
In software, a driver offers a programming interface for managing and controlling particular lower-level interfaces that are frequently connected to a particular kind of hardware or other low-level service.
Therefore, based on the fact that the code you have made is okay, you can make some a notes on what is good and not and then make adjustments.

Answer:
void countUp(int num)
{
if(num==0) //base case.
return;
countUp(num-1);//Recursive call.
cout<<num<<" "; //printing the number.
}
for input num=25
Output:-1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25
Explanation:
I have used recursion to print the numbers the function is in c++ language.In every recursive call we are decreasing num by 1.As the base case is reached.Then it will backtrack from 1 to num and then we are printing while backtracking.
