Calculating an average using variable argument lists

#include <stdio.h> #include <stdarg.h> double average(double j1 , double j2,...); int main() { printf("\n Average = %lf", average(8.5, 4.5, 0.0)); printf("\n Average = %lf", average(3.0, 4.0)); printf("\n Average = %lf\n", average(0.0,1.8,3.5)); } double average( double j1, double j2,...) { va_list parg; double sum = j1+j2; double value = 0; int count = 2; va_start(parg,j2); while((value = va_arg(parg, double)) != 0.0) { sum += value; printf("\n in averge = %.2lf", value); count++; } va_end(parg); /* End variable argument process */ return sum/count; }
