长整型;
s=1;
对于(i=0;i=s)
s=a[i]*a[i+1]*a[i+2]*a[i+3]*a[i+4]*a[i+5]*a[i+6]*a[i+7]*a[i+8]*a[i+9]*a[i+10]*a[i+11]*a[i+12];
}
printf(“%lld\n”,s);
s=1;
对于(i=0;i=s)
s=a[i]*a[i+1]*a[i+2]*a[i+3];
}
printf(“%lld\n”,s);
返回0;
}

这不是详尽的答案,而是指令,以便您可以重写代码,因为没有理智的人会对此进行调试

  • a
    存储在静态内存中。这是4兆字节的数据,你很危险地接近(如果不是过去的话)破坏你的堆栈。这可以通过将
    a
    设置为全局(将其置于
    main
    之外)或静态本地(将其声明为
    static int a[]
    )来实现。声明它
    const
    也是一个好主意。另外,给它一个有意义的名字编辑:证据证明我不知道如何计数。尽管如此,该数组还是没有意义成为可变的自动变量

  • 循环将拯救你。你的整个
    a[i]*a[i+1]*a[i+2]*a[i+3]*…*a[i+N]
    都是同一个术语,计数器从0到N。嘿,计数器,循环就是这样做的,对吗

  • 正确格式化代码。缩进和对齐在使代码段可读性方面有很大的帮助

编辑:我试过了,你的结果是
