Answer:

d. if (radius > 0) System.out.println(radius * radius * 3.14159);

Explanation:

The positive values are those values that are greater than 0(zero).0 is considered to be nonnegative number it is neither positive nor negative and for a zero radius the area will be 0.As we know the are of the circle is π*radius*radius, and π is 3.14159.So the correct answer matching to this condition is option d.

Which checks if the radius is greater than 0 then find the radius and print it.

Margaret [11]

Answer:

The following are the program in the C++ Programming Language:

#include <iostream> //header file

#include <string>  //header file

#include <vector>  //header file

//name space

using namespace std;

//main function

int main() {

  vector<string> word; //set variable

  vector<int> c;  //set variable

  int s, counts = 0; //set variable

  string strng;  //set variable

  cout<<"Enter the size of string: "; //print message

  cin >> s; //get input

  cout<<"Enter the string: "; //print message

  for(int i = 0; i < s; ++i) {  //set for loop

     cin >> strng; //get input

     word.push_back(strng);

  }

  for(int i = 0; i < s; ++i) { //set for loop

         counts = 0;

         for(int j = 0;j<word.size();j++){ //set for loop

       if(word[j] == word[i]){ //set if statement

          counts++; //increament in counts

       }        

     }

      c.push_back(counts);

  }

  for(int i = 0; i < s; ++i) {

      cout << word[i] << " " << c[i] << endl;//print result

  }

  return 0;

}

<u>Output</u>:

Enter the size of string: 2

Enter the string: hello  sir

hello 1

sir 1

Explanation:

Here, we define three header files <iostream>, <String>, <vector> and namespace "std" after that we define main() method inside it.

  • Then, we set two vector type variables first one is string variable "word" and the second one is integer variable "c".
  • Then we set two integer variable "s" and "counts" and variable "counts" assign to 0.
  • Then, we get input from the user in variable "s" for the length of the loop.
  • Then, we set for the loop inside it, we get input in the variable "strng" from the user.
  • Then, we set the for loop for count the string repetition if any word comes again in the string then the value of count will increase.
  • Finally, we set for a loop to print the result.

Internet is a boon or curse
tangare [24]
It really depends on what you're using it for such as looking up a recipe or an answer to a question. If you're using it for illegal purposes or looking up things that are seen as morally wrong by other people it can make the internet seem like a bad thing. But the internet wasn't created with that intended purpose so again it's just your own personal opinion.
