In problem set 1, we wrote a program that solved for the number of connections in a mesh network given the number of nodes using the following formula: Previous Program:  #include #include using namespace std; int main() {     int n = 0;      int c = 0;      cout << "Enter the number of Nodes: ";      cin >> n;      c = n * (n - 1) / 2;      cout << "The number of connections is: " << c << endl;     return 0;  } Where n is the number of nodes, or devices, in the network and c is the number of connections, or links. Rework this program to perform the calculation inside of a value returning function. Your main() function should prompt the user for the number of nodes and pass it as a value parameter to your function. Show your source code and a screenshot of your working program.
