source code is in C++ language

Instructions: Kindly provide comments that explains the program code below. (NOTE: this is a C program language) #include <stdio.h> int fact_recur(int n){if(n==0)  return(1);return(n*fact_recur(n-1));} int fact_for(int n){    int fact=1;    for(int i=1;i<=n;i++){          fact=fact*i;          return fact;  }    }int main(void) {  int number;  printf("input number is: ");      scanf("%d",&number);    printf("factorial using for loop: %d",fact_recur(number));    printf("\nfactorial using recursion: %d",fact_recur(number));  return 0;}

I need this code to be with python 3 1. Approach: Non recursive: //include necessary header files#include <iostream>using namespace std;//main functionint main(){    int days,buy_on_this_day ,sell_on_this_day;    //get number of days as input from user    cout<<"Enter number of days: ";    cin>>days;    int stock_price[days];    for(int i=0;i<days;i++)    {   cout<<"Enter stock_price";        cin>>stock_price[i];    }    int i=0;    for(int i=0;i<days-1;i++)    {        //comparing  current price with next day price and finding the  minima        while(i<days-1 && stock_price[i+1]<=stock_price[i])        i++;         if(i==days-1)        break;        buy_on_this_day  =i++;         while(i<days && stock_price[i]>= stock_price[i-1])        i++;        sell_on_this_day =i-1;        cout<<buy_on_this_day <<" : index of the change before  we buy"<<endl;        cout<<sell_on_this_day<<"  :index…

Modify the following program to which you have to add the amplitude (A) frequency (f) energy (E)this source code is in C++ languageplease help me to run the program #include <iostream>#include <math.h>#include <stdlib.h> main(){    int i,j;    float x;    for(i=0; i<50; i++)    {       for (j=0; j<40+20+exp(-i/20)*sin(i*3.1416/10); j++)       std:: cout <<' ';    std:: cout << '*' << std:: endl;    }    std:: cout << std:: endl;    system("pause");}
