Error of variable-sized object may not be initialized

Question

I get an error on line 9(int studentGrades) saying Error of variable-sized object may not be initialized. ...........................

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int rows = 3;
    int const columns = 5;

    int studentGrades[][columns] = {
        {3,1,4,6,9},
        {4,4,4,6,3},
        {5,4,1,6,8}
    };

    for (int i = 0; i < rows; i++){
        for (int j = 0; j < columns; j++){
            printf("%d ", studentGrades[i][j]);
        }
        printf("\n");
    }
    return 0;
