Why this doesn't output anything?

Question

#include <iostream>
#include <cstdlib>

using namespace std;

int main() {

int m, n[m], sum, media;

cout<<"how many tests did you do?"<<endl<<endl;
cin>>m;

int aux=m;

for(int i=1;i<aux;i++){
cout<<"score in your exam "<<i<<"?";
cin>>n[m];
sum=sum+n[m];
m--;
}

media = sum/aux;

if(media>=5){
cout<<"you passed, your media is: "<<media<<endl;
}
else{
cout<<"you failed, your media is:"<<media<<endl;}

return 0;}

Answer 1

There are lots of problems with this code... Please refer to my fix below.

#include <iostream>
#include <cstdlib>

using namespace std;

int main()
{
int m; int sum = 0; int media;

cout << "Input number of test : " << endl;
cin >> m;

int n[m];

for(int i=0; i < m; i++)
{
cout << "Input score "<< i +1 <<" : ";
cin>>n[i];
sum=sum+n[i];
}

media = sum/m;

if (media >= 5)
{
cout << "You passed. Your media is : " << media <<endl;
}

else
{
cout << "You failed. Your media is : " << media << endl;
}

return 0;
}

okay thanks sm

Answer 3

Because your if and else statements are not included in the main function therefore not compiled.
