We can also use va_arg(ptr, char);
It depends on the variable arguments ur passing to the function
Ex: fun("IndiaBIX", 'I','N','D','I','A' );

The C library macro type va_arg(va_list ap, type) retrieves the next argument in the parameter list of the function with type.

In 1 place in random test you say that va_end should be present for every va_start. But here it compiles with no error. How?

I think num = va_arg(ptr, int);
Keep the value 6 in num and this statement num = va_arg(ptr, int); hold 1 as it is true.

What is the meaning of attach ptr with pointer and why we need to do so ?
va_start(ptr, msg); /* attach ptr with msg */
va_start(ptr, msg); /* attach ptr with msg */

What does int in va_arg(ptr, int) indicates? and is there any case where we can use char over there?

Sir I think va_start (ptr, msg) should hold 6.
And num must return 6. ?
Give me region how it work.
