Question

我的问题与学生的分数排在一起。它以适当的间距打印出分数，但是当它到达if语句以指定字母等级时，它会像ABC一样打印它们而不是以列为中心。任何帮助，将不胜感激。问题出在calc_grades函数if语句中。我无法弄清楚如何让成绩与列

对齐

#include <stdio.h>

int numStus;

问题是如何在if语句中打印出成绩。查看你的print_report函数，你的格式是正确的，那么为什么不以同样的方式保持格式呢？

你有什么：

if (sum2 >= 90)
    {
    printf("A   ");
    }

应该是什么：

if (sum2 >= 90)
    {
    printf("%6c", 'A');
    }

在2D数组中排列Char
