I want to make a program that reads 5 numbers and tell me the largest number, the smallest number and the sum of the numbers, in C ++ using the for loop.

I tried and did so:

#include <iostream>
using namespace std;

int main()
{
  int n, i, h, l, s;

  cout<<"Digite 5 numeros:\n";

  for (i=0; i<5; i++)
  {
      cin>>n;
      s+=n;

      if (n>l)
      {
          n=h;
      }
      else
      {
          n=l;
      }
  }

  cout<<"O maior numero e "<<h<<", o menor e "<<l<<" e a soma e "<<s<<".\n";

  return 0;

}

#include <iostream>
using namespace std;

int main(){
    int n, i, h, l, s = 0; // Inicializar a soma "s" em zero
    cout << "Digite 5 números:\n";

    for(i=0; i<5; i++){
        cin >> n;
        s+=n;
        if (i==0) {l=n; h=n;} // Inicializar os valores de "l" e "h" no primeiro loop
        if (n<l) { l=n; }
        if (n>h) { h=n; }
    }
}

With this code, the sum is started at zero, and the highest and lowest values are initialized with the first value, and starting from that we begin to make comparisons.

1 - Variables are not receiving initial value. 2 - Instead of n > l, make n> h. 3 - When n is greater than the highest current value, you say h = n, not the opposite. Try to do this:

#include <iostream>
using namespace std;

int main() {
    int n, i, high=0, low=1e10, s=0;

    cout<<"Digite 5 numeros:\n";
    for (i=0; i<5; i++)
    {
        cin>>n;
        s+=n;
        if (n>high)
            high=n;
        if (n<low)
            low=n;
    }
    cout<<"O maior numero e "<<high<<", o menor e "<<low<<" e a soma e "<<s<<".\n";

    return 0;
}
