程序为啥运行出错呀？解决思路

程序为啥运行出错呀？
#include <stdio.h>

void Joseph_cycle(int* overall_people,int* each_iteration)
{
  int overall_people_temp= *overall_people;
  int i,j,k,store[overall_people_temp];
  for(i=0;i<overall_people_temp;i++)
  {
  store[i]=0;
  }
  printf("%d\n",store[20]);
}

int main()
{
  int overall_men,each_men;
  printf("input overall number of people:");
  scanf("%d",overall_men);
  printf("input each iteration of people:");
  scanf("%d",each_men);
  Joseph_cycle(&overall_men,&each_men);
}

------解决方案--------------------
scanf();读入整型数据的时候，记得添加 & 符号,正确的格式如下：

C/C++ code

int overall_men，each_men；
scanf("%d",&overall_men);
scanf("%d",&each_men);
