#define _CRT_SECURE_NO_WARNINGS
#include <stdio.h>
#include <stdlib.h>
//implement recusrive function summ
double recsum(int n)
{
	if (n == 0)
	{
		//base recursion
		double a;
		printf("Enter the number: ");
		scanf("%lf",&a);
		return a;
	}
	double a;
	printf("Enter the number: ");
	scanf("%lf", &a);
	return a + recsum(n - 1);
}
int main()
{
	int n;
	printf("n=");
	scanf("%i", &n);
	double sum = recsum(n-1);
	printf("%0.1lf\n", sum);
	return 0;
