Select notes to be printed

Question

I need to print only the notes above >=6, in which place of the code I put the if or some other instruction?

I tried and I couldn’t find the right place.

#include <iostream>
#include <string.h>
using namespace std;

#define MAX 50

struct aluno {
    char nome[50];
    int matricula;
    float nota;
};

void imprime(aluno v[], int num);

int main(void) {
    // Declara um aluno
    aluno alunos[MAX];

    alunos[0].matricula = 12014432;
    alunos[0].nota = 7.5;
    strcpy(alunos[0].nome,"Fulano");
    alunos[1].matricula = 13022301;
    alunos[1].nota = 5.9;
    strcpy(alunos[1].nome,"Sicrano");
    alunos[2].matricula = 11024122;
    alunos[2].nota = 4.0;
    strcpy(alunos[2].nome,"Beltrano");
    alunos[3].matricula = 11014120;
    alunos[3].nota = 6.1;
    strcpy(alunos[3].nome,"Huguinho");
    alunos[4].matricula = 11024012;
    alunos[4].nota = 8.0;
    strcpy(alunos[4].nome,"Zezinho");
    alunos[5].matricula = 11014117;
    alunos[5].nota = 3.5;
    strcpy(alunos[5].nome,"Luizinho");

    imprime(alunos, 6);

}

void imprime(aluno v[], int num) {
    int i;

    for (i=0; i<num; i++) {

        cout << "Mat.: " << v[i].matricula << endl;
        cout << "Nome: " << v[i].nome << endl;
        cout << "Nota: " << v[i].nota << endl;
    }
}

Answer 1

Which part is printing what you want? Currently prints the grade of all students, right?

    cout << "Mat.: " << v[i].matricula << endl;
    cout << "Nome: " << v[i].nome << endl;
    cout << "Nota: " << v[i].nota << endl;

This, right?

Then the if should encapsulate all of it and nothing more than it. The stretch that sweeps the whole vector is this:

for (i=0; i<num; i++) {

    cout << "Mat.: " << v[i].matricula << endl;
    cout << "Nome: " << v[i].nome << endl;
    cout << "Nota: " << v[i].nota << endl;
}

Then it would be:

for (i=0; i<num; i++) {
    if (v[i].nota >= 6) {
        cout << "Mat.: " << v[i].matricula << endl;
        cout << "Nome: " << v[i].nome << endl;
        cout << "Nota: " << v[i].nota << endl;
    } 
}

I put in the Github for future reference.
