#include <stdio.h>

    char c;
    int a=1,b;
    int d[1000];
    while(1){

        if(c=='\n'){
            break;
        }
        d[a]=c;
        a++;
    }
    for(a=a-1;a>=1;--a){

应该是d[a]=a-'0'

@red_hair_steve 不是很懂啥意思qwq

#include <stdio.h>
int main(){
    char c;
    int a=1,b;
    int d[1000];
    while(1){
        scanf("%c",&c);
        if(c=='\n'){
            break;
        }
        d[a]=c;
        a++;
    }
    for(a=a-1;a>=1;--a){
        printf("%c",d[a]);
    }
    return 0;
}

现在为啥还是WA但是示例是正常的

#include<bits/stdc++.h>
using namespace std;
int main(){
    double q;
    long long d,y,c,a,b,e;
    cin>>q;
    d=q*10;
    b=d/1000;
    c=d/100%10;
    a=d/10%10;
    y=d%10;
    cout<<b/1000.0+c/100.0+a/10.0+y;
    return 0;
}

@zhangbochen 我学习的是C，还不会C++，不过还是谢谢你qwq

@cuiboming 可不可以根据我的代码改一下呢qwq

你d[i]是int类型的

by zhangbochen @ 2023-10-21 16:27:50

@CountStars 哦好吧~
