有没有学过的帮着看一下，本人刚学还搞不明白🙏🙏

#include <stdio.h>

int main()
{
    
    float i = 1;
    int n = 1;
    while(n < 366){
        if(n % 6 == 0 || n % 7 == 0){
            i *= 0.99;
        }else{
            i *= 1.01;
        }
        n ++;
    }
    printf("%f\n",i);
    return 0;
}

#include<stdio.h>


int main()
{
    double ans=1;
    for(unsigned i=1; i<=100; ++i) {
        int x=i%7;
        if(x==6||!x) ans-=(ans*0.01);
        else ans+=(ans*0.01);
    }
    printf("%lf\n",ans);
    return 0;
}
