Help me, I couldn't find why the matrix is taking more than 9 values in SL[][]...

```c #include <stdio.h> int a, SL[2][2]; a = 2; int assign_value() { int i,j,etu_max, mod; int max = 0; int b_mod = 0; for(i=0;i<a;i++) { for(j=0;j<2;j++) { scanf("%d", &SL[i][j]); if(SL[i][j] > max) { max = SL[i][j]; etu_max = i; mod = j; } if(SL[i][j] > b_mod) j = b_mod; } } printf("Best student %d with the best grade %d in %d", etu_max, max, mod); }; int main() { assign_value(); } // Matrice M[etudiant][module] that contains Section A's results. // Best student? // Subjects with the best ranking? ``` Was trying to make a matrix that contain students, subjects and students marks in subjects + printing the best mark of a student + printing the best subject from the marks, but the program isn't working and I couldn't figuer it out.
