The following code will program that prompts the user to enter the num- ber of hours a car is parked at the airport and outputs the parking fee.
<u>Explanation:</u>
Code:
#include<iostream>
using namespace std;
int main()
{
float hours;
cout <<"Enter number of hours a car parked at the airport: "; // prompt the user to enter hours.
cin >> hours ; // strong the hours
if (hours > = 0 && hours < =3 ) // if 0 < = h < = 3
cout << "Parking fee: 5"; //printing parking fee is 5.
else if (hours > 3 && hours < = 9)//if 3 < h < = 9
cout<<"Parking fee: "<<6*int(hours);//converting float value to int the multiplying with 6 then printing fee.
else//if 9 < h < = 24
cout<< "Parking fee: 60";// printing parking fee 60.
return 0;
}
All four are true, technically.
But the right answer is probably the third one.
Answer:
D. Create a cell reference in a formula by typing in the cell name or clicking the cell.
Further Explanation:
To create a cell reference in a formula the following procedure is used:
First, click on the cell where you want to add formula.
After that, in the formula bar assign the equal (=) sign.
Now, you have two options to reference one or more cells. Select a cell or range of cells that you want to reference. You can color code the cell references and borders to make it easier to work with it. Here, you can expand the cell selection or corner of the border.
Again, now define the name by typing in the cell and press F3 key to select the paste name box.
Finally, create a reference in any formula by pressing Ctrl+Shift+Enter.
Answer:
- country_pop = {
- 'China': 1365830000,
- 'India': 1247220000,
- 'United States': 318463000,
- 'Indonesia': 252164800
- }
- for key in country_pop:
- print(key + " has " + str(country_pop[key]) + " people")
Explanation:
The solution code is written in Python 3.
Given a dictionary, country_pop with data that includes four country along with their respective population (Line 1-6). We can use for in loop structure to traverse through each of the key (country) in the dictionary and print their respective population value (Line 7-8). The general loop structure through is as follow:
for key in dict:
do something
One key will be addressed for each round of loop and we can use that key to extract the corresponding value of the key (e.g. country_pop[key]) and print it out.
