    Help converting!!!

    Hi, I'm trying to finish this program for art class and my friend helped me but he put it in some weird stuff that I don't understand. Is there a way to change this code into code that I can use? I use devc++ and we've always been taught to use cout<<"lol"<<endl; and stuff like that but he used some weird printf commands and stuff that I don't get, any help would be appreciated thanks.


    Code:
    #include <cstdlib>
    #include <stdio.h>
    #include <time.h>
    #define title "MathTest"
    #define quests 9 // questions in one game\set
    #define miss 6 // wrong answers allowed before gameover
    //Addition test params (number range): 
    #define add_min 1
    #define add_max 9
    //Subtraction test params (number range): 
    #define sub_min 1
    #define sub_max 9
    //Multiplication test params (number range): 
    #define mul_min 2
    #define mul_max 9
    //Division test params (number range): 
    #define div_min 2
    #define div_max 9
    char uname[16]; // users name
    int key = -1; // for main menu, keyboard input
    int one, two, sol; // variables for test
    int i, q;
    int tries; // tries left (to give right answer)
    //statistics:
    int st_right, st_wrong, st_total, st_questions;
    int sl_right, sl_wrong, sl_total;
    bool solved, playing; // booleans
    
    int random(int min, int max) //returns random in range min..max
    {
        return rand() % (max - min + 1) + min;
    }
    int random(int max) //returns a random in range 1..max
    {
        return rand() % max + 1;
    }
    
    void comment(char con) // returns a random comment\taunt for a specified situation
    {
        if (con == '~') // wrong answer

    I suggest that you just google "printf". There are plenty of references on what it's about.
    As far as I know, there's no tool for converting "printf" to "cout".

    This is what happens when you have others do your homework for you. Good luck on your tests.
