Aleksandr [31]

Answer:

Explanation:

1. Write a program that declares an array named alpha with 50 components of the type double. Initialize the array so that the first 25 components are equal to the square of the counter (or index) variable and the last 25 components are equal to three times the index variable.

double alpha[50];

for (int i=0;i<25;i++)

{

alpha[i]=i*i;

alpha[i+25]=(i+25)*3;

}

2. Output the array so that exactly ten elements per line are printed.

for (int i=0;i<50;i++)

{

cout<<i+1<<". "<<alpha[i]<<" ";

if (((i+1)%10)==0)

{

cout<<endl;

}

}

3. Run your program again, but this time change the code so that the array is filled with random numbers between 1 and 100.

double alpha[50];

for (int i=0;i<50;i++)

{

alpha[i]=rand()%101;

}

for (int i=0;i<50;i++)

{

cout<<i+1<<". "<<alpha[i]<<" ";

if (((i+1)%10)==0)

{

cout<<endl;

}

}

4. Write the code that computes and prints the average of elements of the array.

double alpha[50],temp=0;

for (int i=0;i<50;i++)

{

alpha[i]=rand()%101;

temp+=alpha[i];

}

cout<<"Average :"<<(temp/50);

5. Write the code that that prints out how many of the elements are EXACTLY equal to 100.

double alpha[50],temp=0;

for (int i=0;i<50;i++)

{

alpha[i]=rand()%101;

if(alpha[i]==100)

{

temp++;

}

}

cout<<"Elements Exacctly 100 :"<<temp;

Please note: If you put each of above code to the place below comment it will run perfectly after compiling

#include <iostream>

using namespace std;

int main()

{

// If you put each of above code here it will run perfectly after compiling

return 0;

Illusion [34]

Answer:

static void Main(string[] args)

{

//declare a blank linked list

LinkedList<int> numList = new LinkedList<int>();

Console.WriteLine("Enter the Numbers");

//check if the size of the linkedlist is 10

while(numList.Count < 10)

{

//read the input supplied by the user

string val = Console.ReadLine();

//check if the input is integer

if(int.TryParse(val, out _) == false)

{

//if not integer, display error message and prompt for new number

Console.WriteLine("Invalid number");

continue;

}

//add the inputted number to the linkedlist

numList.AddLast(int.Parse(val));

}

//call the method for linkedlist sum and display it

Console.WriteLine(SumLinkedList(numList));

Console.Read();

}

//method for linkedlist summation

private static int SumLinkedList(LinkedList<int> val)

{

//declare sum as zero

int sum = 0;

//loop through the linkedlist to display the num and sum all numbers

foreach(int item in val)

{

Console.Write(item + " ");

sum += item;

}

return sum;

}

}

anzhelika [568]

Answer:

Following is given the program code as required:

Explanation:

Initially a class is created name RandomGuessMatch.java
An instance for scanner class is created in main method.
Now the upper and lower bounds for guess are given by variables MIN (1) and MAX(5).
Now user will be allowed to guess the number.
The difference between the guessed number and actual number is calculated.
This will tell the compiler weather to print correct or incorrect.
