input().strip()
Problem: If I want to take a number as input, would I also need the .strip() method? Like this: n = int(input().strip()) Instead of just coding: n = int(input()) I know .strip() returns a copy of the string in which all chars have been stripped from the beginning and the end of the string. But I wonder why / if it is necessary.

c++ read numbers from file line by line
Problem: I have a text file with on every line one or more integers, seperated by a space. How can I in an elegant way read this with C++? If I would not care about the lines I could use cin >>, but it matters on which line integers are. I have a problem tomunderstand each line of numbers.

How to get integer input from user in c# console application?
Problem: At this very moment I am eagerly searching the way to read an integer which was given by a user from a command line or console project. I primarily know C++ and I also have recently started down with the C# path. I know that the Console.ReadLine() only takes the char/string. So in short now I am looking for the integer version of Console.ReadLine().

How to fix the given error about class vector?
In an array the name of the array is a pointer to the array. So in iArray and & iArray [0] the same value is obtained. What I do not understand very well, is what is happening when I try to repeat this with myvector. int iArray [] = {1,2,3,4}; cout << ... [0] << endl; Print me different addresses. Working with vectors, is there any way to know where element 0 is, by the name of the vector?
