Re: C++ random between two choices ?

Here's how to do it:

C++ Syntax (Toggle Plain Text)
  1. int choices[2] = {2,3}; //choose between 2 and 3
  2. // Seed the random generator with srand()
  3. // Use rand() to pick either 0 or 1 and store in variable x
  4. int L = choices[x];

Google for srand() and rand() to find out how they work, or read this

Re: C++ random between two choices ?

u can use the function that i gave as

C++ Syntax (Toggle Plain Text)
  1. char x = random('A', 'B');
just change its prototype to
C++ Syntax (Toggle Plain Text)
  1. char random(char a, char b);

i hope thats simple enough. i guess thats simplest way to do it.
