Help with random command.

[dualdark]

Hello everyone, im doing this tic tac toe program for my class... it is done, but the last requisite is that the first move must be define randomly, and i dunno how to do it... i know i need rand command, but i dont have an idea how to implement in the code..

for(y=0; y<3; y++){
        a[y]=0;
    }

    cout <<"Player 1: ";
    cin >>jug1;
    cout <<"Player 2: ";
    cin >>jug2;
    cout <<endl<<endl<<jug1<<". X"<<endl;
    cout <<jug2<<". O"<<endl<<endl;
    cout <<"| 1 | 2 | 3 |" << endl;
    cout <<"-------------" << endl;
    cout <<"| 4 | 5 | 6 |" << endl;
    cout <<"-------------" << endl;
    cout <<"| 7 | 8 | 9 |" << endl<< endl ;
    cout <<"Choose a number."<<endl<<endl;
    for(x=0; x<3; x++){
        for(y=0; y<3; y++){
            matriz[x][y]=' ';
        }
    

thanks, any help will be so much appreciated

One of those 3 examples looks like what you need. I assume you need an integer between 0 and 8?

well, noy really... i just need the random number to define which player will make the first move... =S

All the information you need is in the link mutexe provided.
You just have to think about how to use it.

 
  int first_player; 

  srand(time(NULL);                    // Randomize the the seed 
  first_player = rand() % 2 + 1;  // Will result in 1 or 2
