Write a C++ program that open the text file “numbers.txt”.
(the numbers.txt looks like: ' 1. 6 8 ')
Have a “output.txt”
If summation is less than 5, your code must write last number inside “numbers.txt” in “output.txt”, else it must write the number in between in “output.txt”
(use conditional statement for comparison)
`Hey,
Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries
#include <iostream>
#include <fstream>
using namespace std;
int main() {
int sum_of_num = 0, fist_num, lst_num, cnt = 0; // summation of the
numbers in file initialized to 0
int a; // variable 'a' holds each integer after reading it
ifstream File; // File object creation
File.open("numbers.txt"); // numbers.txt is opened
if (!File) {
cout << "Error opening file";
return 0;
}
freopen("output.txt", "w", stdout);
int i=0;
while (File >> a) { // reading each integer and summing it
up
if(i==0){
fist_num = a;
i++;
}

python Create a program to open a text file for reading, find the maximum number in the file, determine if that maximum number is even, and write to an output text file. You should either write Yes if the number is even, otherwise write the maximum number. You should note the following: • Your input file must be named input.txt • The input file has one integer number per line • Your output file must be named output.txt • Your...
Write a C++ program that reads text from a file and encrypts the file by adding 6 to the ASCII value of each character. See section 5.11 in Starting out with C++ for information on reading and writing to text files. Your program should: 1. Read the provided plain.txt file one line at a time. Because this file has spaces, use getline (see section 3.8). 2. Change each character of the string by adding 6 to it. 3. Write the...
If you have a file named phone-numbers.txt that looks like this: 207-568-6723 617-277-2343 207-822-9645 603-314-5892 800-233-3413 Doing "sort phone-numbers.txt" will end up sorting by area code.

Write a simple telephone directory program in C++ that looks up phone numbers in a file containing a list of names and phone numbers. The user should be prompted to enter a first name and last name, and the program then outputs the corresponding number, or indicates that the name isn't in the directory. After each lookup, the program should ask the user whether they want to look up another number, and then either repeat the process or exit the...
Write a PYTHON program that allows the user to navigate the lines of text in a file. The program should prompt the user for a filename and input the lines of text into a list. The program then enters a loop in which it prints the number of lines in the file and prompts the user for a line number. Actual line numbers range from 1 to the number of lines in the file. If the input is 0, the...
