input txt)
- - - + - - 50 31 54 v0 61 44 75
I have to read the above input txt in c++ to implement arithmetic expression tree. the v0 is a variable that we have to assign later. The headers we are allowed to use are as below.
#include <list>
#include <stack>
#include <queue>
#include <fstream>
#include <iostream>
#include <vector>
I really do not get how I should read the input.txt and store them. at first I tried to read them as string and convert them but I am not allowed to use string header. If I read the above input txt as char, it won't be able to store more than 2 digit integers. please help me

So to read the .txt file and its contents, we can use fstream class >> operator to read from the file word by word. So even a single character will be represented as a word and even a multi digit integer is a word. this way u can read anything word by word .
below is the code for that :

Write a program that will input data from the file
Lab13.txt(downloadable

a name, telephone number, and email
address.
Store the data in a simple local array to the main
module, then sort the array by the names. You should have several
functions that pass data by reference.

Hi! 1. I need some help with sorting string in a text file. My goal is to 1 shift left strings for string.length time. I was able to do that successfully. However, I am also trying to sort, using insertion sort , the resulting shifts. I store all shifts in a vector (or is it better to use an array?!) , and try to sort them that way, but my output is just the shifted strings but not sorted. Can...
