Write a single statement that assigns to the variable uname a string consisting of the first character in the user's first name plus the first 4 characters of their last name. Assume the user will have 2 or more names. Do not change the case of any character (e.g., upper case to lower case). Use the functions rfind, substr, and the + operator.

BELOW is the given code.

#include #include

using namespace std;

int main() { string fullname, uname; cout << "Enter your full name:" << endl; getline(cin, fullname); //your solution goes here

cout << "Username: " << uname << endl; return 0; }

PLEASE DO IT CORRECTLY.
