#include <stdio.h>

int main() {
    int n, i, x;
    double sum = 0;
    scanf("%d", &n);
    for (i = 0; i <= n; i++) {
        scanf("%d\n", &x);
        sum += x;
    }
    printf("%0.2f",sum / n);
}

@zian123 循环改为for(int i=0;i<n;i++)

#include <stdio.h>

int main() {
    int n, i, x;
    double sum = 0;
    scanf("%d", &n);
    for (i = 1; i <= n; i++) {
        scanf("%d\n", &x);
        sum += x;
    }
    printf("%0.2f",sum*1.0 / n);
}

// 循环多了一次， 0到小于等于n是循环n+1次，改成从1开始就行了
