You are required to open a file for input and read the data in that file into an array (named data). Use the variable size to count how many elements in the file. Create the file yourself in notepad and call it data.txt so that it has the following numbers in order: 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0
Please help with this. In C please
#include <stdio.h> int main() { FILE *fp = fopen("data.txt", "r"); if (fp) { int data[1000], size = 0, num, i; while (fscanf(fp, "%d", &num) != EOF) { data[size++] = num; } // print data in array printf("Numbers read from file are:\n"); for (i = 0; i < size; ++i) { printf("%d\n", data[i]); } fclose(fp); } else { printf("data.txt does not exists!\n"); } return 0; }

For your second program, please read the data from the input file directly into an array. (You may safely dimension your array to size 300.) Then close the input file. All subsequent processing will be done on the array. Your program should have two functions besides main(). The first function will print out the contents of the array in forward order, 10 numbers per line, each number right justified in a 5 byte field. The second function will print out...
Please help in C: with the following code, i am getting a random 127 printed in front of my reverse display of the array. The file i am pulling (data.txt) is: 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 when the reverse prints, it prints: 127 9 8 7 6 5 4 3 2 1 0 9 8 7 6 5 4 3 2 1 not sure why...please...
In C++, how would I read data from a .txt file into an array? For example, I have an assignment that requires me to read temperatures from a file named data.txt into an array. How would I go about doing this?
ArraysAndFiles.java and PartiallyFilledArray.java. They are shells that do not do anything. You will be adding code after the comments in the main method and using the javadoc documentation to implement the other methods. Task 1: Send array data to the screen In ArraysAndFiles.java, create a new method printOnScreen and compile it. In the main method of ArraysAndFiles.java, add the code to declare and initialize the array of Strings and call printOnScreen to print the array on the screen. Task 2:...
IN JAVA Read the runners data file into arrays. ONE string array and ONE 2-dimension array. Each runner has 8 pieces of data, which includes name, and how much they ran for each of 7 days. Print out the raw data in columns. Below the raw data, print out the total miles ran for all of the runners. THIS IS TXT FILE : Keith 10 8 4 5 12 3 2 Anna 9 8 7 6 5 12 13 Derick...
JAVA - the program should output as follows: Please enter a seed: 2345 Please enter the size of the array: 1 Array size must be greater than 1. Please reenter: 0 Array size must be greater than 1. Please reenter: -1 Array size must be greater than 1. Please reenter: 8 Please choose an option: 1 Print the array 2 Find the average 3 Find the largest element 4 Count how many times 3 occurred 5 Count how many elements...
In Unix/Linux, input and output are treated as files and referenced by the operating system using file descriptors. When you open a shell session, for example, three file descriptors are in use: 0 standard input (stdin) 1 standard output (stdout) 2 standard error (stderr) By default, the command interpreter (shell) reads keyboard input from file descriptor 0 (stdin) and writes output to file descriptor 1 (stdout), which appears on the screen. As you explored in Lab 2, input/output can be...
Write a C++ that read a list of numbers from a .txt file into array. The first digit on the list will be array size, while the second number on the list will be our first number in our array list. Example: t1.txt file contain list off input number: 5, 3, 6, 10, 43, 23. notice the first number is 5 which will need to be use as an array size and the rest of the numbers are in the...
I've managed to do all other questions but this one baffled me.. Page 2 of 2 0 - 200m + 6) Load the data file (data.txt) which is given below into an array. Display an error message if the file cannot be opened. Design C codes to find the maximum value, count the number of positive values and the number of odd values. (25 Marks) data.txt (Note: you need to create and save the data file, a, b, c, d,...
Therefore, for this program you will read the data in the file named weatherdata_2.txt into arrays for the wind speed and for the temperature. You will then use the stored data to calculate and output the average wind speed and the average temperature. Create a constant with a value of 30 and use that to declare and loop through your arrays and as a divisor to produce your averages. Here is the data file (below). 1. 14 25 2. 12...
