else if (choice == 'c')

{

int num, tries=0;

num = rand() % 101 + 100;

do

{

cout << "The computer's guess is " << num<< endl;

if (num < random)

{

cout << "Sorry, your guess is too low, try again! ";

num++;

}

if (num < random)

{

cout << "Sorry, your guess is too high, try again!";

num--;

}

}while (num != random);

}

}while (choice != 'q');

return 0;

}

How do i get the computer to randomize its guess?
