Hi, I am trying to figure out how write a code to read in a list of integers separated by commas into an array in c++, while ignoring the commas.
example input
5, 2, 8, 6, 3, 6, 9, 7
example array:
int arr[] = {5,2,8,6,3,6,9,7};
Homework Answers
NOTE :- I am assuming that list is present in a file
C++ program :-
#include <iostream>
#include <fstream>
using namespace std;
int main() {
int num[100];
int i = 0;
if(ifstream in {"list_f.txt"})
{
int x;
while((in >> x) && in.ignore()) //read number and
ignore comma in a loop untill end of file
{
num[i]=x;
i++;
}
}
else
{
cout<<"The file is unable to open"<<endl;
}
}

Hi! I am struggling trying to figure out how to do this. For this lab, you must have two implementations of calculating the Fibonacci sequence. You are required to calculate it utilizing an array and then with a pointer. You must use the array provided and you must malloc space for your pointer. Your algorithms must be in-place, meaning they do not use a temporary variable to calculate the next sequence number. Lastly, you must insert a comment above each...

I am trying to write the following code using pointers and traversal by pointers instead of indexing (in C++). The following code is correct: void shift(int arr[], int n) { int temp = arr[n - 1]; int temp1; for (int i = 0; i < n; i++) { temp1 = arr[i]; arr[i] = temp; temp = temp1; } } This is my ATTEMPT at writing it with pointers (and traversal by pointers!) but I know it is wrong. I believe...

What am I doing wrong? Write a loop to populate the list user_guesses with a number of guesses. Each guess is an integer. Read integers using int(input()). Sample output with inputs: 3 9 5 2 user_guesses: [9, 5, 2] num_guesses = int(input()) user_guesses = [] num_guesses = 3 user_guesses = [] guess = 0 while guess < num_guesses: number = int(input()) user_guesses.append(number) g uess +=1 print('user_guesses:', user_guesses) Your output user_guesses: [6, 8, 3] Expected output user_guesses: [6, 8, 3, 5]

Step 4: Write a Sum Function Since we can write, compile and run simple c files, lets add a bit to make a program that will sum an entire array of integers. To do this we are going to simply overwrite the main.c file to include the new function. The sum function below is not complete and must be finished before the program will execute properly. %%file main.c #include <stdio.h> int sum(int array[], int arrayLength) { int i =...

5.13 LAB: Output numbers in reverse Write a program that reads a list of integers, and outputs those integers in reverse. The input begins with an integer indicating the number of integers that follow. For coding simplicity, follow each output integer by a space, including the last one. Assume that the list will always contain fewer than 20 integers. Ex: If the input is: 5...

Hi - For Python, I am trying to find the first maximum value in an array. I currently have written numpy code: first_max_index = int(np.where(biofuel_int_array == max_biofuel_int)[0][0]) Is there another way to identify the first maximum index in the array, without using a loop?
