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:
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:
using namespace std;
I have C code like this:

The ordered and unordered map containers (std::map and std::unordered map) are included in the standard library.
The items in an ordered map are sorted by key, and insert and access are in O (log n).
For ordered maps, the standard library often use red black trees.
However, this is only an implementation detail.
Insert and access are in O in an unordered map (1).
It is simply another term for a hashtable.
An illustration using (ordered) std::map:
int main(int argc, char ...READ MORE

Replace pow() with the previous iteration's value.
There is no need for code to call pow ().
Pow(x, 5 * I - 1) and pow(-1, I - 1) may be formed since both have an int exponent dependent on the iterator I from the previous loop iteration.
Let f(x, i) = pow(x, 5 * i ...READ MORE
