C 线程：信号SIGABRT（lldb）和程序以退出代码-1结束

程序停止，线程出现在sprint的行中：

sprintf(x,"%d",x2);

这不是将int x2转换为stringx的最佳方法吗

int check(int n,char [8]);

int main(){
    char x[8]="0";
     int N,x2;

    scanf("%d",&N);
    while(strlen(x)<9){
        if(check(N,x)) printf("%s\n",x);
        x2=atoi(x);
        x2++;
        sprintf(x,"%d",x2);
        }
    return 0;
    }


int check(int n,char x[8]){
    int l,i,y,count;
    l=strlen(x);
    y=atoi(x);
    count=0;
    for(i=0;i<l;i++){
        count=count+pow((x[i]-'0'),n);
    }
    if(count==y) return 1;
    else return 0; }

如果您已经发布了编译行+实际编译的代码，即包含了正确的头，那么它会更有用！。当移动到数组大小为10时，虽然需要一段时间才能退出，但效果良好！：

修改后的代码：

C:\...>cat main.c

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

int check(int n,char [10]);

int main(){
    char x[10]="0";
     int N,x2;

    scanf("%d",&N);
    while(strlen(x)<9){
        if(check(N,x)) printf("%s\n",x);
        x2=atoi(x);
        x2++;
        sprintf(x,"%d",x2);
        }
    return 0;
    }


int check(int n,char x[10]){
    int l,i,y,count;
    l=strlen(x);
    y=atoi(x);
    count=0;
    for(i=0;i<l;i++){
        count=count+pow((x[i]-'0'),n);
    }
    if(count==y) return 1;
    else return 0; }

世界上一切都好！：D

charx[8]=0；而whilesrlenx，但即使char x[9]=0，它也将是同一个线程并退出-1，因为循环在终止之前打印一次长度为9的字符串。。。当char x[10]=0时它还会崩溃吗？是的，这是一样的！SIGABRT线程可能是用于Sprint的。我检测到***堆栈崩溃***:./foo在程序结束时终止，这在将所有字符[8]转换为字符[10]时是固定的。你是对的，但确实需要一段时间，所以我将尝试不使用任何字符串，而只使用整数，希望它能解决时间问题：
