代码：

#include<cstdio> #include<cstdlib> #include<iostream> #include<sstream>#include<string>#include<cstring>#include<vector>#include<map>#include<stack>#include<queue>#include<algorithm>#include<cmath>#include<ctime>using namespace std;#define b -10;int main(){int a[10];srand(time(NULL));for(int i=0;i<10;i++){a[i] = rand()-10000;}for(int i=0;i<10;i++){int r = a[i] % b;cout << "a[i]" << a[i] << "r" << r<< endl;}return 0;}

结果：

a[i]9998r8
a[i]-1123r-3
a[i]2128r8
a[i]-4219r-9
a[i]19625r5
a[i]3299r9
a[i]21875r5
a[i]-4229r-9
a[i]22506r6
a[i]1530r0
