c++报错啦，但是我不会改

问题遇到的现象和发生背景

问题相关代码，请勿粘贴截图 48 11 D:\学习文件\未命名4.cpp [Error] expected unqualified-id before '[' token

 int a;
    string name[] = {"Wang", "Zhang", "Li", "Zhao","He","Liu"};
    int score[]={100, 90, 52, 0,76,88};
    for (int i = 0;i<6;i++)
    {
        a.[i]getInfo();
    }
    cout << "学生总人数：" << Grade::count;
    return 0;

请问各位这要怎么办呀

运行结果及报错内容

我的解答思路和尝试过的方法

我想要达到的结果

int a[6];
    char name[][6] = { "Wang", "Zhang", "Li", "Zhao","He","Liu" };
    int score[] = { 100, 90, 52, 0,76,88 };
    for (int i = 0; i < 6; i++)
    {
        a[i]=getInfo();
    }
    cout << "学生总人数：" << Grade::count;
    return 0;

a.[i]getInfo();这条语句怎么来的？如果有getInfo()方法，改为

a[i]=getInfo();
