Matrix as parameter passage in C

Question

Hello, my doubt is the following, I would like to know how I do in the code below, so that my matrix is read inside the main, and after inside the subprogram, a vector receives the values of this matrix and and and displays the matrix read?

#include <stdio.h>

#define tam 4


void exibirresultado(int provNot[][3]);

int main(){
     int provNot [tam][3];
     int i,j;

     printf("\n #########################################\n");

            for(i=1; i<=tam; i++){
            printf("Digite a nota do  %d aluno:\n",i);
                for(j=0; j<3; j++){
                    printf("Prova %d :\n",j+1);
                    scanf("%d",&provNot[i][j]); 
            }
        }
            exibirresultado(provNot);

    }   
    void exibirresultado(int provNot[][3]){
        int i,j,teste[tam][3];
                for(i=1; i<=tam; i++){
                    for(j=0;i<3;j++){
                        teste[i][j]=provNot[i][j];
                    }
                }
                    for(i=1; i<=tam; i++){
                    for(j=0;i<3;j++){
                        printf("%d === %d",i, teste[i][j]);
                    }
                }
    }

Answer 1

Good night. To display the content contained in the array addresses you can use this code:

int matriz[LINHA][COLUNA] = {{1,2,3}, {4,5,6}, {7,8,9}};
int i, j;
for(i = 0; i < LINHA; i++)
 for(j = 0; j < COLUNA; j++)
  printf("%d \n", matriz[i][j]);

Answer 2

Arrays are indexed in 0, so the interactions stay:

for(i=0; i<tam; i++)

The index for the evidence (j), to iterate on them, always make comparison with the total evidence, no i:

for(j=0; j<3; j++)

Improve your code:

A #define tam 4 It’s not very intuitive. Seek to use names that resemble what they store/contain:

#define TOTAL_PROFS 4
#define QUANT_PROVAS 3

int notas_alunos [TOTAL_PROFS][QUANT_PROVAS];

Avoid using variable names such as i, especially when one is learning, because they are easily confused, and it is necessary to understand what they do there.
