You have to read a file with 10 integers into an array named read_arr. Assume the file has been associated with the ifstream fin and num is a variable of integer data type. What will work? Group of answer choices (a) for(int i=0;i<10;++i) read_arr[i]=(fin>>num); (b) for(int i=0;i<10;++i) { fin>>num; read_arr[i]=num; } (c) int i=0; while(fin>>num) { read_arr[i]=num; ++i; } Both (b) and (c) ===================== Which of the following is a correct struct declaration?

a file named numbers.txt contains an unknown number of lines, each consisting of a single positive integer. Write some code that reads through the file, ignoring those valuse that are not bigger than the maximum value read up to that point. The numbers that are not ignored are added, and their sum stored in a variable called runsum. using python. rfile = open("numbers.txt", "r") maxvalue = 0 runsum = 0 data = rfile.readline() for data in rfile: if int(data) > maxvalue: maxvalue = int(data) runsum += int(data) my code so far. not sure what i am missing

This Phyton: In this lab, you will write a program that reads integers from a file “data.txt” into a list, print the list and the sum of the numbers in the list. The file contains one integer per line. You are not required to do any exception handling. Your program should not prompt the user for any input. The input file is “data.txt”. First, create a file “data.txt” and put the numbers add the numbers 3, 1, 5, 2 into it, one number per line as shown in the sample “data.txt” file below. Sample “data.txt” file 3 1 5 2 Then, write the following functions: read_numbers(filename) Read numbers from the given file and return a list of contains the numbers from the file. compute_sum(numbers) Compute the sum of the given the list numbers. Do not use the built-in sum function. main() Read numbers from the file “data.txt”, print the list, and compute the sum and print it. Main will use the two functions above to get the job done. Sample run: [3, 1, 5,…

Write a function that reads a single line of numbers from a file named "question1.txt", and returns the average of the numbers read. For example, if the file is as follows: ----- question1.txt ----- 1 3 5 -2 4 0 6 -2 -3 ------------------------- then the function must return 12/9 = 1.33333 """ def file_average(): return # Remove this line to answer this question
