Question

#include <stdio.h>

int main(void) {
int input = -1;
double average = 0.0;
  
/* Use this for your input */
scanf("%d", &input);
  
/* This is the only output you need */
printf("%.1lf", average);
return 0;
}

Please write a C coding program (make it simple coding)  that find the average of sequence integer. when user enter integers, once at a time. Also, If the user enters 0 (zero), the code will calculates the average and then prints it, and then exits.

#include <stdio.h>

int main(void) {
        int input = -1;
        double average = 0.0;
        int count = 0;
          
        do {
                scanf("%d", &input);
                if(input != 0) {
                        count++;
                        average += input;
                }
        } while(input != 0);
          
        if(count != 0) {
                average = average/count;
        }
        
        /* This is the only output you need */
        printf("%.1lf", average);
        return 0;
}
