So, I have a problem when programming in C++, could you help?

Question

make a program that fills a vector of 5 positions with integers, after that, sweep this vector and show on the screen only those that are divisible by 3, if all are not divisible, show the message "none is divisible"
but i can't find a way to show the message

the code:

#include <iostream>

using namespace std;

int c[5],h,i;

int main()
{
    for(i=0;i<5;i++){
    
    cout<<"Insira o valor desejado: ";
    cin>>c[i];
    }
    for(i=0;i<5;i++) {
      
       if (c[i]%3==0){
          cout<<c[i]<<" " << "\n";
          
       } else {
         cout <<"nenhum  ";
        }
    }
       
    return 0;
}

Answer 1

Please, see below your code modified on how to print numbers divisible by 3.

Also, your description talks about a vector, but your implementation uses an array. Double-check if this is what you want to do.

#include <iostream>

using namespace std;

const int SIZE = 5;

int c[SIZE], h, i;

int main()
{
    for (i = 0; i < SIZE; i++)
    {
        cout << "Enter a number: ";
        cin >> c[i];
    }
    
    cout << "Numbers divisible by 3:";
    
    for (i = 0; i < SIZE; i++)
    {
        if (c[i] % 3 == 0)
            cout << " " << c[i];
    }
       
    return 0;
}
