Answer:

Following are the statement is given below

if(updateDirection ==1) // check condition

{

++numUsers; // increments the value

}

else

{

--numUsers; // decrement the value

}

Explanation:

Following are the description of statement

  • Check the condition in the if block .If the "updateDirection" variable is 1 then then control moves to the if block otherwise control moves to the else block statement.
  • In the if  block the statement is "++numUsers" it means it increment the value by 1 .
  • In the else block the statement is "--numUsers" it means it decrement  the value by 1 .

Which of the following code segments does not contain any errors?
Readme [11.4K]

Answer:

c. double triple(float n) { return (3 * n); }

Explanation:

In option a print is used to print integer.While printf is used in C to print something.

In option b there is no * operator between s s s it should be s*s*s.So it will give error.

In option d there is also no multiply operator * in between 3.14 2 r it should be 3.14*2*r.

So we can say that option c is error free.

Write a program that first calls a function to calculate the square roots of all numbers from 1 to 1,000,000 and write them to a
svlad2 [7]

Answer:

The csharp program to compute square roots of numbers and write to a file is as follows.

class Program  

{  

static long max = 1000000;  

static void writeRoots()  

{  

StreamWriter writer1 = new StreamWriter("roots.txt");  

double root;  

for (int n=1; n<=max; n++)  

{  

root = Math.Sqrt(n);  

writer1.WriteLine(root);  

}  

}  

static void Main(string[] args)  

{  

writeRoots();  

}  

}

The program to compute squares of numbers and write to a file is as follows.

class Program  

{  

static long max = 1000000;  

static void writeSquares()  

{  

StreamWriter writer2 = new StreamWriter("squares.txt");  

long root;  

for (int n = 1; n <= max; n++)  

{  

root = n*n;  

writer2.WriteLine(root);  

}  

}  

static void Main(string[] args)  

{  

writeSquares();  

}  

}  

Explanation:

1. An integer variable, max, is declared to hold the maximum value to compute square root and square.

2. Inside writeRoots() method, an object of StreamWriter() class is created which takes the name of the file as parameter.

StreamWriter writer1 = new StreamWriter("roots.txt");

3. Inside a for loop, the square roots of numbers from 1 to the value of variable, max, is computed and written to the file, roots.txt.

4. Similarly, inside the method, writeSquares(), an object of StreamWriter() class is created which takes the name of the file as parameter.

StreamWriter writer2 = new StreamWriter("squares.txt");

5. Inside a for loop, the square of numbers from 1 to the value of the variables, max, is computed and written to the file, squares.txt.

6. Both the methods are declared static.

7. Inside main(), the method writeRoots() and writeSquares() are called in their respective programs.

8. Both the programs are written using csharp in visual studio. The program can be tested for any operation on the numbers.

9. If the file by the given name does not exists, StreamWriter creates a new file having the given name and then writes to the file using WriteLine() method.

10. The csharp language is purely object-oriented language and hence all the code is written inside a class.

A function defined beginning with void SetNegativesToZeros(int userValues[], ... should modify userValues such that any negative
Stels [109]

Answer:

   public static void setNegativesToZero(int userValues[]){

       System.out.println("Array before setting negatives to zero "+Arrays.toString(userValues));

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

           if(userValues[i]< 1){

               userValues[i] = 0;

           }

       }

       System.out.println();

       System.out.println("Array After setting negatives to zero "+Arrays.toString(userValues));

   }

Explanation:

Using Java programming Language, the method is created to receive an array of ints as parameter (as specified in the question)

Using a for loop, we iterate over the entire array checking for values that are negative (<0) and setting them to zero.

See a complete program below

import java.util.Arrays;

import java.util.Scanner;

public class num1 {

   public static void main(String[] args) {

   // Create an array and assign values

       int [] arr = {1,2,3,-1,1,2,-4};

   //Calling the method setNegativesToZero

   setNegativesToZero(arr);

   }

//Creating the Method

   public static void setNegativesToZero(int userValues[]){

       System.out.println("Array before setting negatives to zero "+Arrays.toString(userValues));

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

           if(userValues[i]< 1){

               userValues[i] = 0;

           }

       }

       System.out.println();

       System.out.println("Array After setting negatives to zero "+Arrays.toString(userValues));

   }

}
