Instruction: Explain the functions of each code per line to get the desired result.

#include <iostream>
using namespace std;

int main(){
    int n,i;
    float db[100], sum=0.0, avg; 
    cout<<"Enter array length: "; 
    cin>>n;
    
    for(i=0;i<n;++i){ 
        cout<< i+1<<". Enter number: ";
        cin>>db[i];
        sum+=db[i]; 
        
    }

    sum = sum + db[i];
    cout<<"Sum = " <<sum << endl;
    avg = sum/n;
    cout<< "Average = " <<avg;
}

Enter array length: 5
1. Enter number: 12.5
2. Enter number: 3
3. Enter number: 31.6
4. Enter number: 22.3
5. Enter number: 18
