c++ 数组的定义 已经简单的运用

#include<iostream>
using namespace std;
int main(){
int a[10],b[10];//定义俩个数组 a,b
for ( int i = 0;i < 10; i ++ ){
    a[i] = 2 * i - 1;
    b[10 - i - 1] = a[i];
}
for ( int i = 0;i < 10 ;i++){
    cout << "a[" << i <<"] = "<<a[i]<<" "; 
    cout << "b[" << i <<"] = "<<b[i]<<" "<<endl; 
}
return 0;
}
