Hi, could you write this for C++?

CHALLENGE ACTIVITY 5.3.2: Function stubs: Statistics. Define stubs for the functions called by the below main(). Each stub should print "FIXME: Finish FunctionName(" followed by a newline, and should return -1. Example output: FIXME: Finish GetUserNum() FIXME: Finish GetUserNum) FIXME: Finish ComputeAvg() Avg: -1 1 #include 2 using namespace std; 3 4 /* Your solution goes here */ 5 6 int main() { 7 int userNum1; 8 int userNum2; 9 int avgResult; 10 11 userNum1 = GetUserNum(); 12 userNum2 = GetUserNum(); 13 14 avgResult = ComputeAvg(userNumi, user Num2); 15 16 cout
