What is "String Concatenation" exactly?

[Cairus]

I have been instructed not to use string concatenation in a project but this terminology hasn't been defined yet in the book or in class.

Looking online every example seemed really complicated and didn't make sense.

If someone could explain or show me this in the simplest way they could it be appreciated.

Following this is my code that I don't know if it falls into this catagory.

#include <iostream>
using namespace std;

void showStars(int numStars);


int main()
{
    int N;
   cout << "How many stars would you like to show?: ";
   cin >> N;

   showStars(N);
    return 0;
}

void showStars(int numStars)
{
    for (int row = 0; row < numStars; row++)
    {
        cout << "*";
        for (int totstars = 0; totstars < row; totstars++)
        {
            cout << "*";
        }
        cout << endl;
    }
}

To "concatenate" (or just "catenate") is to append, or connect together.
https://www.google.com/search?q=define%3A+concatenate

For example, the strings "foo" and "bar" can be concatenated to yield the string "foobar".
In C, we'd do this with the standard C library function strcat(), which you are not using, or if we had objects that had type std::string, we'd concatenate them with the plus sign, like this:

#include <string>
using namespace std;

int main()
{
  string a = "foo";
  string b = "bar"; 

  // concatenate a and b to yield "foobar", store the result in c.
  string c = a + b;
}

so based on that definition it looks like my program falls outside of those parameters correct?
