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

#include <iostream>  

using namespace std;  

int main(){  
//declaring variables  
  int i,f=1,num;  // variables 
   //Print the Prod of first N int
  cout<<"N = ";    
  cin>>num;  
  cout<<"Factorial of " <<num; " = "; 
  for(i = 1;i<=num;i++){  // every variable i is added depending on N variable on how many and will be multiplied with f
      cout<<"("<<i<<")";
      f=f*i;    
  }   
  cout<<" = "<<f;  
  return 0;  
}      

N = 4
