跪求代码为何出错

Question

#include<cstdio>#include<cstring>#include<iostream>#include<algorithm>using namespace std;struct shujupaixu{    int xuhao ;    int shuju ;    int num ;};bool cmp ( shujupaixu a , shujupaixu b ){    return a.shuju < b.shuju ;    if( a.shuju == b. shuju )    {        return a.xuhao < b.xuhao ;    }}int main(){    shujupaixu arr[100001];    int i = 0 , j = 0 ;    while(scanf( "%d %d" , &arr[i].xuhao , &arr[i].shuju ) != EOF)    {        i ++ ;        arr[i].num = i ;    }    sort ( arr , arr+i , cmp ) ;    for ( j = 0 ; j < i  ; j ++ )    {        printf ( "%d %d\n" , arr[j].xuhao , arr[j].shuju ) ;    }    return 0 ;}

Answer 1

修改为：shujupaixu arr[1000];  数组申请的空间太大，不可分配内存了
