[Error] invalid conversion from 'int' to 'int (*)[4]' [-fpermissive]

代码瑕疵望理解
报错显示：[Error] invalid conversion from 'int' to 'int (*)[4]' [-fpermissive]
Windows11，使用c++dev5.11编译器
感谢指点
报错句已用注释标出

studentGrades[STUDENT][EXAMS]改成studentGrades

(studentGrades[STUDENT][EXAMS],STUDENT,EXAMS)
这是什么呀，是个逗号表达式啊，你是不是想写个函数调用，但是忘记写函数，只写了个括号
void (*processGrades[4])( int grades[][EXAMS], int pupils, int tests)
你这函数声明就有问题啊，函数名呢，函数没名字吗
