Question

I’m new in C and would love to get some help regarding multipule input
for example I have this struct:

typedef struct person{
    char * name;
    int age;
  }

and I want to write a function that get’s :name age name age name age…
Is there a way I can do that ? how can I later get the values?

I mean something like :

void my_func(char* name, int age , char* name1,int age1.....)

like in JAVA I can use “…”
I want to do something like that :

void my_func(char* name, int age , char* name1,int age1.....){ 
  int num_of_ppl = length of the input/2
  person p1 ;
  p1.name = first input name
  p1.age = first input age

etc..

thanks!

If you want a function with variable argument list you can use va_list

#include <cstdarg>
using namespace std;
void myFunction(int num, ...)
{
    va_list arguments;                           // A place to store the list of arguments
    va_start ( arguments, num );                 // Initializing arguments to store all values after num
    for ( int x = 0; x < num; x++ )              // Loop until all numbers are added
        func(va_arg ( arguments, person ));      // get next value of argument and call a function
    va_end ( arguments );                        // Cleans up the list

}
