return random symbol &\ or number?
How do I get a program to return a random Symbol (%*&+-) etc. and/or numbers from a given set (2 4 6 8) to a user?
I'm using Visual c++ on XP.

...by getting a random number over the range of the array index values containing the symbols.
#include <cstdlib> #include <ctime> //seed the random number generator with time() function srand(static_cast<unsigned>( time(0))); //generate random number from 0 to count-1 random_number=random(count); //Function to generate a random integer 0 to count -1 int random(int count) { return static_cast<int>((count*static_cast<long>(rand()))/(RAND_MAX+1)); } From Ivor Horton's Beginning C++ 6.
