谁能用C语言敲一下这个代码呀，救救孩子吧

#include<stdio.h>
int main(){
    double s;
    int n,i;
    s=1;
    scanf("%d",&n);
    for(i=n;i>=1;i--){
        s=s*(1+1.0/i);
    }
    printf("%.1f",s);
    return 0;
}

#include <stdio.h>
int main(void)
{
    int n = 0;
    scanf("%d", &n);
    printf("%.1lf", (double)(n + 1));
    return 0;
}
