can we use or in arguments c++ code example

Example 1: c++ variable arguments

#include <iostream>
#include <cstdarg>
using namespace std;

double average(int num,...) {
   va_list valist;               // A place to store the list of arguments (valist)
   double sum = 0.0;
   int i;
   
   va_start(valist, num);        // Initialize valist for num number of arguments
   for (i = 0; i < num; i++) {   // Access all the arguments assigned to valist
      sum += va_arg(valist, int);
   }
   va_end(valist);               // Clean memory reserved for valist
   
   return sum/num;
}

int main() {
   cout << "[Average 3 numbers: 44,55,66] -> " << average(3, 44,55,66) << endl;
   cout << "[Average 2 numbers: 10,11] -> " << average(2, 10,11) << endl; 
   cout << "[Average 1 number:  18] -> " << average(1, 18) << endl; 
}

/*
NOTE: You will need to use the following 'data_types' within the function
va_list   :  A place to store the list of arguments (valist)
va_start  :  Initialize valist for num number of arguments
va_arg    :  Access all the arguments assigned to valist
va_end    :  Clean memory reserved for valist
*/

Example 2: what are parameters in c++

#include <iostream>

// Define name_x_times() below:
void name_x_times(std::string name, int x){
while(0 < x){
  std::cout << name << ""
}
}

int main() {
  
  std::string my_name = "Add your name here!";
  int some_number = 5; // Change this if you like!
  // Call name_x_times() below with my_name and some_number
  
  
} // this put shit inside of the shit, look back at your adventure.cpp code future me.
