[Solved] C++ generate 25 digit random number?

Question

Declare an array of twenty-six characters. In a loop from zero to twenty-four (inclusive) generate a random value between '0' and '9', and add to the array. Terminate the array with the string terminator. Now you have a string with 25 random decimal digits.

For the actual random-number generation, I suggest you look into the new C++11 random number functionality, especially std::uniform_int_distribution.

Combine that with the std::generate function from the standard algorithm library, and you can do it with just a couple of lines.
