In C please

Define stubs for the functions called by the below main0. Each stub should print "FIXME: Finish FunctionNameO followed by a newline, and should return-1. Example output FIXME: Finish GetUserNum() FIXME: Finish GetUserNum () FIXME: Pinish ComputeAvg) #include 3 Your solution goes here int main(void) 6 int userNum1 7 int userNum2; 8 int vgResult; 11 userNum2 GetUserNum); 13 avgResult - ComputeAvg(userNum1, userNum2); 15 printf("Avg: dn, avgResult); 17 return 0
