Program to calculate square root c++

Making a C++ application to determine a number's square root.  The built-in arithmetic operator "sqrt" is not used in this application.  There are two variables: one for the user-inputted integer and the other for the number's square root.  This software does not function very well, and I am certain that there is a more effective method to accomplish it: Here is my full code: #include <iostream> using namespace ...READ MORE

When and why do I need to use cin.ignore() in C++?

In C++, I developed a simple application that requested the user to enter a number and then a string.  Surprisingly, when I ran the application, it never paused to ask for the string.  It simply ignored it.  After conducting some research on StackOverflow, I discovered that I needed to include the following line: cin.ignore(256, '\n'); before the line with the string input  That addressed the problem and allowed the software to run.  My issue is why C++ need the cin.ignore() line, and how can I forecast when I will need to use it. Here's the software I created: #include <iostream> #include <string> using namespace std; int main() { ...READ MORE
