In c++, please and thank you! Write a function that dynamically allocates an array of integers. The function should accept an integer argument indicating the number of elements to allocate. The function should return a pointer to the array.
c++ computer language what is the output of the following code segment? int main() { int myarray[]={-200, 33, 89, 50, 44}; sub(myarray, 5); for(int i =0; i<5; i++) cout<<myarray[i]<<" "; cout<<endl; system("pause"); return 0; }; void sub(int arr[], int z) { for(int i =0; i<z; i++) arr[i] = arr[i] - i; }
Topic: pointers, dynamic array and command line arguments Write a complete C++ program named “showHelp” that accepts command line arguments. It checks whether there is a command line argument of “/help” or“/?” or “-help” followed by a topic number. It will print out “yes, topic number(<number>) if there is one. Otherwise, it prints out “no, topic number(N/A) For example, if you run this program with correct arguments as follows, it willprint out yes and its associated topic number respectivelyshowHelp /? 101showHelp /debug /help 102showHelp /print /help 103 /verboseshowHelp -verbose -debug -help And if you run the program with invalid arguments, it will print no, in all casesshowHelp -helpshowHelp 101 /?showHelp 101 102 /help /verboseshowHelp /? /help -helpNote: command line arguments are simply an array of pointers to C-string. example code: #include <iostream> using namespace std; int main(int argc, char** argv){...}
(Initialize array) Write a function called initializeArray that receives an array, its size, and two integers and initializes the array with random values between the first integer and the second integer. Write another function called printArray that receives an array and its size and prints the array elements in a column. Write a test program that declares and initializes an array of size 20 with random values between 0 and 10 inclusive, and then prints the array using the above functions Write a C++ program that declares and initializes an integer array of size 100 with random integers between 1 and 10 inclusive using initializeArray (from question 1) and counts the occurrence of each number in the array and graphs the information in the form of a bar chart or histogram—each number is printed, then a bar consisting of that many asterisks is printed beside the number. Here is a sample run of the program: Number Value Histogram 1…

Use printArray (from question 1) to print the values of count. Here is a sample run of the program: 1…
In C++ commas must be there. main.cpp #include <vector>#include <string>#include <iostream> using namespace std; // TODO: Write method to create and output all permutations of the list of names.void PrintAllPermutations(const vector<string> &permList, const vector<string> &nameList) { } int main() { vector<string> nameList; vector<string> permList; string name; // TODO: Read in a list of names; stop when -1 is read. Then call recursive method. return 0;}
C++ Code 9.16 Lab 06: Dynamic Arrays (Part 2) Step 1a: Preparation The suite of Part 1 tests has been moved to its own function. The code in main() is focused on testing the new operators you'll write in this part. main() relies on a change you're going to make to the DynamicArray::print() member function (coming up in Step 1b). Instead of directly using cout, this member function is now going to print to a stringstream. This allows my test code to examine the output and check it automatically. How 3 representative lines of the new main program work: // Use stringstream to capture your print function's output.stringstream testoutput;// Use the same testoutput variable over and over, so we reset it to the empty string between tests using its str() member function.testoutput.str(""); // Reset test output string// Call the print function on your array, and it prints to testoutput instead of cout.a.print(testoutput);// Use the RunIndividualTest function also included in main.cpp to…

(Pointers + Dynamic 1D Arrays) c++ program please use only pointers and dynamic 1D array and please don't use recursion and vector or other
help me solve this in c++ please Write a program that asks the user to enter a list of numbers from 1 to 9 in random order, creates and displays the corresponding 3 by 3 square, and determines whether the resulting square is a Lo Shu Magic Square. Notes Create the square by filling the numbers entered from left to right, top to bottom. Input validation - Do not accept numbers outside the range. Do not accept repeats. Must use two-dimensional arrays in the implementation. Functional decomposition — Program should rely on functions that are consistent with the algorithm.
In C++, When an array is passed to a function as a pointer, the function doesn't know the size of the array. List 3 ways to handle this problem.
Instructions: In Basic C Language In the code editor, you are provided with a main function that asks the user for an integer input and passes this value to a function called, getFactorial() The getFactorial() function has the following description: Return type - int Name - getFactorial Parameters - one integer Description - returns the factorial of the passed integer Your implementation should be RECURSIVE and you should not use any loops Input #include<stdio.h> int getFactorial(int); int main(void) { int n; printf("Enter n: "); scanf("%d", &n); printf("Factorial of %d is %d", n, getFactorial(n)); return 0;} int getFactorial(int n) { // TODO: Implement this recursive function} Output should be: Enter n: 3 Factorial of 3 is 6
