Answer 1

When you do that:

    struct aluno;

You are trying to declare a variable incorrectly. Remove this line as aluno was previously declared as a 5 position array with the type of the struct.

Notice that line:

    printf("Determine a Matricula do Aluno &d: ", i+1);

Instead of &d, you should use %d.

Those first two printfshould be within the for, and not before him.

In his second for, you use three notes, but you didn’t declare the three in struct.

I think what you wanted was this:

#define MAX 50
struct {
    int ra;
    char nome[MAX];
    float prova[3];
} aluno[5];

int main() {
    int i;
    int j;

    for (i = 0; i < 5; i++) {
        printf("Determine o Nome do Aluno %d: ", i + 1);
        fgets(aluno[i].nome, MAX, stdin);

        printf("Determine a Matricula do Aluno &d: ", i + 1);
        scanf("%i", &aluno[i].ra);

        for (j = 0; j < 3; j++) {
            printf("Determine a nota da %d Prova: ", j + 1);
            scanf("%f", &aluno[i].prova[j]);
        }
    }
    return 0;
}
