    Help with random in my code

    I cannot figure out where to put in randomize(); in this code so that the numbers are truly random. I can only get them to stay the same for a long time and then change by 1, or change by 1 each time, or sometimes not change at all. Here is my code...
    Note that fight is a function I call, and that the //1, //2, etc. was just for me to fix some problems with missing brackets.
    Code:
    					
    	if (choice1 == 1) {
    cout<<"He grunts, turns around, and stumbles towards you."<<endl;
    						
    fight (health,stoner_health);}
    
    			}
    	return 0;
    }
    
    fight (int fighter1, int fighter2)
    	{//1
    
    int fight_choice;
    while (fighter2>0 || fighter1>0) {
    cout<<"Do you want to Punch(1) or Kick(2)?"<<endl;
    cin>>fight_choice;
    
    	switch(fight_choice) {//2
    		case 1: {//3
    		int strike;
    		strike = random(5);
    		int damage;
    		damage = random(5);
    		cout<<"You punch for "<< damage << " damage."<<endl;
    		fighter2 = fighter2 - damage;
    		cout<<"They are down to "<< fighter2 << " health"<<endl;
    		cout<<"They attack you for " << strike << " damage."<<endl;
    		fighter1 = fighter1 - strike;
    		cout<<"You are down to " << fighter1 << " health."<<endl;
    		getch();
    		clrscr(); }//3
    		break;
    
    		case 2: {//4
    		int strike2;
    		strike2 = random(8);
    		int damage2;
    		damage2 = random(8);
    		cout<<"You kick for "<< damage2 << " damage, but leave yourself open for attack."<<endl;
    		fighter2 = fighter2 - damage2;
    		cout<<"They are down to "<< fighter2 << " health"<<endl;
    		cout<<"They attack you for " << strike2 << " damage."<<endl;
    		fighter1 = fighter1 - strike2;
    		cout<<"You are down to " << fighter1 << " health."<<endl;
    		getch();
    		clrscr(); 
                                    break; }//4
    			}//2
    			}
    I'm not here. This isn't happening

    I'm not familiar with randomize, but:
    Code:
    #include <time.h>
    #include <stdio.h>
    
    srand(time(NULL));
    
    someRandomInt=rand() % 100;
    i'm assuming randomize is like the srand call i used, therefore, call it just before you call each random (or in my case rand).
    PHP and XML
    Let's talk about SAX

    No, call srand(time(NULL)) ONCE at the start of main. After that, use rand().

    this random works best for me...
    I used it in my game as well.

    Code:
    #include <stdio.h>
    #include <stdlib.h>
    #include <time.h>
    #include <iostream.h>
    #include <conio.c>
    
    int main()
    {
    
    for (int x=0;x>=0;x++)
    {
      time_t now;
      time(&now);
      
      printf("%s", ctime(&now));
      Sleep(100);
      clrscr();
      
    }
    return main();
    }
