Where is the best place to self learn c++ or c# that is free?
Elina [12.6K]

Answer:

udemy

Explanation:

Hello guys, you might know that C++ is one of the most popular and powerful object-oriented programming languages and if you want to do low-level stuff then it’s the best language to start with.

You will find applications written in C++ on a wide range of fields like embedded programming, server-side application, gaming, and even high-frequency trading applications. Most of the complex software like Operating Systems, Database Management Systems, and Powerful trading systems are written in C++.

While many of us have learned to program by using C and C++, let me honest with you learning C++ is challenging. There are many areas that are tough to grasp like points but you will learn them slowly and that’s where these free C++ courses will help you.

There is no doubt that learning C++ will open several opportunities for you. There is a huge demand for good C++ developers, especially in the area of high-frequency trading where every microsecond matter and power of C++ is absolutely needed.

C++ is the language which provides the best of both world, it allows you to use OOP to manage the complexity of software but at the same time, it also allows you to get close to your machine and access all of your computer’s hardware, which is not easily possible for other object-oriented languages like Java or Python.

That’s the reason C++ is heavily used for writing native device drivers, high-end desktop games and complex artificial intelligence programs where you need high performance.

In this article, I am going to share with you some of the best and free courses to learn C++ online at your own time and place and free of cost. You can use these courses if you are starting with programming or you have some experience in coding but not familiar with C++.

Array Challenge Have the function ArrayChallenge (arr) take the array of numbers stored in arr and return the string true if any
vampirchik [111]

Answer:

The code is given as follows,

Explanation:

Code:

#include <stdio.h>

#include <string.h>  

int n; //to store size of array  

char* ArrayChallenge(int arr[]) //function returns string true or false

{

  int i, j;

  int sum = 0;

  for(i = 0; i < n; i++)

  {

      sum = sum + arr[i]; //count sum

  }  

  for(i = 0; i < n; i++)

  {

      for(j = i+1; j < n; j++) //loop for every two elements in array

      {

          if(arr[i]*arr[j] > 2*sum) //check if proudct of two elements > 2 times sum

          {

              printf("\n%d x %d = %d, 2xSum = %d\n", arr[i], arr[j], arr[i]*arr[j], 2*sum);

              return "true"; //If proudct of two elements > 2 times sum. return true

          }

      }

  }

  return "false"; // If proudct of two elements < 2 times sum. return false

}  

int main()

{  

  printf("\nEnter size of array: ");

  scanf("%d", &n); //read size of array

  int A[n]; //array of size n

  printf("\nEnter array elements: ");

  int i;

  for(i = 0; i < n; i++)

  {

      scanf("%d", &A[i]); //read array from stdin

  }

  printf("%s\n",ArrayChallenge(A)); //ccall function and print answer

 

  return 0;

}

Write a computer program that determines how many grades are between 0 and 19.
True [87]

Answer:

public class nnn {

   public static void main(String[] args) {

       int [] examScores = {31, 70, 92, 5, 47, 88, 81, 73, 51, 76, 80, 90, 55, 23, 43,98,36,87,22,61, 19,69,26,82,89,99, 71,59,49,64};

       int zeroTo19 = 0;

       int nineteenTo39 = 0;

       int fortyTo59 = 0;

       int sixtyTo79 = 0;

       int eightyTo100 = 0;

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

           if(examScores[i]<=19){

               zeroTo19++;

           }

           else if(examScores[i]>19&&examScores[i]<=39){

               nineteenTo39++;

           }

           else if(examScores[i]>39&&examScores[i]<=59){

               fortyTo59++;

           }

           else if(examScores[i]>59&&examScores[i]<=79){

               sixtyTo79++;

           }

           else {

               eightyTo100++;

           }

       }

       System.out.println("0 - 19 is "+zeroTo19);

       System.out.println("20 - 39 is "+nineteenTo39);

       System.out.println("40 - 59 is "+fortyTo59);

       System.out.println("60 - 79 is "+sixtyTo79);

       System.out.println("80 - 100 is "+eightyTo100);

   }

}

Explanation:

  • This has been solved with Java
  • Create an array of the exam scores
  • Create new variables for each of the score range
  • Use multiple if statements as u loop through the array to determine the range of scores
  • Finally outside the loop print them variables out

Using selection sort, how many times longer will sorting a list of 40 elements take compared to a list of 5 elements
Hoochie [10]

It will take 8 times more time to sort a 40-element list compared to the time spent on a 5-element list.

We can arrive at this answer as follows:

  • We can see that if we divide a group of 40 elements into groups containing 5 elements, we will have 8 groups.
  • In this case, the time it would take to sort the list of one group of 5 elements would be repeated 8 times so that we could sort all the groups and their elements.

Another way to do this is to divide the number 40 by 5. We would have the number 8 as a result, which indicates that we would need 8 times more time to sort a list of 40 elements, compared to a list of 5 elements.
