Given a two-dimensional array named scores with double type elements, write the embedded loop to navigate this array and multipl

y each element in the array by 10, and put the embedded loop inside a method named increase , and the only parameter of this method is a double type two-dimensional array. This method increase should have void as its return type.
Required:
Write the one line of code to invoke the increase method inside main. Do you need to receive the return value of increase with a local variable, why or why not?

Answer:

Following are the code to this question:

void increase(double scores[][]) //defining method increase

{

//defining loop to multiply the value by 10

for(int x=0;x<scores.length;x++)

{

for(int y=0;y<scores[x].length;y++)

{

scores[x][y]=scores[x][y] * 10; //multiply value

}

}

}

increase (scores);  //call method and pass the value

Explanation:

Description to this question can be described as follows:

  • In the above-given code, a method increase is declared, in which we pass a double array "scores", and inside the method two for loop is defined.
  • Inside the loop an integer variable "x and y"  is used, which multiply by 10 in the score array.
  • In the next line method is called, that accepts array value, in this method calling we can't need to receive the return value because it increases, and it does require a void return type.

Write a program whose input is a character and a string, and whose output indicates the number of times the character appears in
Zina [86]

Answer:

Here is the C++ program:

#include <iostream> // to include input output functions

using namespace std; // to identify objects like cin cout

int counter(string userString, char character) { //function counter

   int count = 0;   // counts the no of times a character appears in the string

   for (int i=0;i<userString.length();i++)  

// loop to move through the string to find the occurrence of the character

       if (userString[i] == character) //if characters is found in the string

           count++;   //counts the occurrence of the character in the string

   return count; }   //returns the no of times character occurs in the string

int main() { //start of the main() function body

   string s; // stores the string entered by the user

   cout<<"Enter a string: "; //prompts user to enter the string

   cin>>s; //reads the string from user

   char ch; //stores the character entered by the user

   cout<<"Enter a character: "; //prompts user to enter a character

   cin>>ch; //reads the character from user

   cout << counter(s, ch) << endl; }  

//calls counter function to find the number of times a character occurs in the //string

Explanation:

The counter function works as following:

It has a count variable which stores the number of occurrences of a character in the userString.

It uses a for loop which loops through the entire string.

It has i position variable which starts with the first character of the string and checks if the first character of userString matches with the required character.

If it matches the character then count variable counts the first occurrence of the character and in the userString and is incremented to 1.

If the character does not match with the first character of the userString then the loops keeps traversing through the userString until the end of the userString is reached which is specified by the length() function which returns the length of the string.

After the loop ends the return count statement is used to return the number of occurrences of the character in the userString.

The main() function prompts the user to enter a string and a character. It then calls counter() function passing string s and character ch arguments to it in order to get the number of times ch appears in s.

The output is attached in a screenshot.

Assume the method doSomething has been defined as follows: public static void doSomething (int[] values, int p1, int p2) { int t
Dmitriy789 [7]

Answer:

The answer to this question is option "b".

Explanation:

In the method definition, we perform swapping. To perform swapping we define a variable "temp" that swap values of variable p1 and p2 and store in array that is "values". and other options are not correct that can be defined as:

  • In option a, It does not insert any new value in array because we do not pass any value in function.
  • In option c, The function does not copy and assign a value in a new array because in this function we not assign any new array.  
  • In option d, It is incorrect because it can not move an element into high index position.
