Example of variable length arguments
Variable-length arguments, also known as varargs, allow a function or method to accept an arbitrary number of arguments, whose number may vary from one function call to another. This is useful when you want to create a function that can handle different numbers of arguments without having to define a different function for each possible number of arguments.
Here given code implementation process.
/*
C program for
Example of variable length arguments
*/
#include <stdio.h>
#include <stdarg.h> // For variable arguments
void example(int n,...)
{
va_list record;
// va_list with num number of arguments
va_start(record, n);
printf("\n Given %d paramter is ",n);
// Execute loop through by parameter length
for (int i = 0; i < n; ++i)
{
// Display i-th paramter value
printf("\n %d",va_arg(record, int));
}
// Clear the allocate memory
va_end(record);
}
int main()
{
// First paramter indicate number of variable arguments
// Test A
// number of parameters 5
example(5, 1, 4, 3, 9, 6);
// Test B
// number of parameters 2
example(2, 11, 42);
}Output
Given 5 paramter is
