您应该用代码框框全

by wzmzmhk @ 2021-08-15 17:15:55

他的代码

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int k, n;
    double Sn = 0.0;
    for (n = 1; Sn <= k; n++)
    {
        Sn += 1 / n;
    }
    printf("%d", n);
    return 0;
}

大佬的代码

#include<stdio.h>

int main()
{
    int k, n;
    double sn = 0.0;
    scanf("%d", &k);
    for (n = 1;; n++) {
        sn += 1.0 / n;
        if (sn > k * 1.0)
            break;
    }
    printf("%d", n);
    return 0;
}

#include <stdio.h>
#include <stdlib.h>
int main() 
{ 
int k,n; double Sn=0.0;
for(n=1;Sn<=k;n++) 
{ 
Sn+=1/n;
}
printf("%d",n);
return 0;
}
#include<stdio.h>
int main()
{ 
int k,n; double sn=0.0;
scanf("%d",&k); 
for(n=1;;n++)
{
sn+=1.0/n; if(sn>k*1.0) break;
} 
printf("%d",n);
return 0;
}

重新排版了一下，建议学习一下Markdown

@GoatLeo 循环条件改一下

by wzmzmhk @ 2021-08-15 17:17:02

@GoatLeo 明显的错误：你的判断结束循环条件错误

by GoatLeo @ 2021-08-15 20:16:42

@短笛无腔 我看不出区别啊，怎么改呢

by GoatLeo @ 2021-08-15 20:50:14

@短笛无腔 啊哈，解决了，谢谢大佬
