Answer:

the array must first be sorted.

Explanation:

Binary search is an efficient algorithm used to find an item from a sorted list of items by using the run-time complexity of Ο(log n), where n is total number of elements.

Binary search applies the principles of divide and conquer.

In order to do a binary search on an array, the array must first be sorted in an ascending order.

What is a data broker?
AleksAgata [21]

Answer:

The correct option is a.

A business that collects personal information about consumers and sells that information to other organizations.

Explanation:

Data brokers, also known as data suppliers, data fetchers, information brokers, or even data providers are businesses or companies (even individuals) that, on the most basic level, source and aggregate data and information (mostly information that are meant to be confidential or that are in the real sense difficult to get) and then resell them to third parties. These third parties could be other data brokers.  

They collect data and information from a wide range of resources and sources - offline and/or online e.g web access history, bank details, credit card information, official records (such as birth and marriage certificates, driver's licenses).  

Brokers can steal round about any information. Examples of information that brokers legally or illegally steal are full name, residential address, marital status, age, gender, national identification number, bank verification number. Brokers and hackers are siblings.

A couple types of data brokers are:

1. Those for fraud detection

2. Those for risk mitigation  

Hope this helps!

I need help with Python. The first image is the code and the 2nd is the output.
Gekata [30.6K]
The issue arises because the string you are trying to print is not a string, rather a float value. Item1, item2 and item3 are strong values (if you type some alphabets in it and not just numbers), but itemonecost, itemtwocost, and itemthreecost are explicitly type casted to float. In line 22, 23, and 24 you’re trying to print a float, by adding it with the string. One cannot add numbers to string. Rather you can type cast the itemcost to string while printing.

Add str(itemonecost) instead of itemonecost in print statement. Do this for other float variables too.

However do note that there are multiple ways to correct this issue, and I’ve just pointed one out.

           int age,choice;

           char gender;

           float bmr;

           // inputs

           cout<<"\n Enter weight(in pounds) : ";

           cin>>weight;

           cout<<"\n Enter height(in inches) : ";

           cin>>height;

           cout<<"\n Enter age(in years) : ";

           cin>>age;

           cout<<"\n Enter gender(M for male , F for female) : ";

           cin>>gender;

           cout<<"\n Are you :\n 1. Sedentary \n 2. Somewhat active(exercise occasionally)\n 3. Active(exercise 3-4 days per week)\n 4. Highly active(exercise everyday)? ";

           cout<<"\n Choice(1-4) ";

           cin>>choice;

           //calculate bmr based on the gender

           if(gender == 'm' || gender == 'M')

           {

                       bmr = 66+(6.3*weight)+(12.9*height)-(6.8*age);

           }else if(gender == 'f' || gender == 'F')

           {

                       bmr = 655+(4.3*weight)+(4.7*height)-(4.7*age);

           }

           // update bmr based on how active the user is

           if(choice ==1)

                       bmr = bmr + (20*bmr)/100;

           else if(choice == 2)

                       bmr = bmr + (30*bmr)/100;

           else if(choice ==3)

                       bmr = bmr + (40*bmr)/100;

           else if(choice ==4)

                       bmr = bmr + (50*bmr)/100;

           // output

           cout<<"\n The number of chocolate bar that should be consumed = "<<ceil(bmr/230);

           return 0;

}

//end of program
