character

I'm new to programming in C and have been given the task of creating a 2D array that stores random letters from A-Z using the random () function. I know how to do random numbers.

nextvalue = random ( ) % 10001;

but am unsure on how exactly to create a random character. I know that you can use ASCII to create a random character using the range 65 - 90 in the ASCII table. Can anyone help me come up with a solution? I would greatly appreciate it.

I have this code for a arraylist of entities. All the entities use the same random and so all of them move in the same direction. How can I change it so it generates a new random number for each entity? public void moveFemale() { for(int i = 0; i < 1000; i++){ random = rand.nextInt(99); … >>> More

I've read about it on a message board - Random class isn't really random. It is created with predictable fashion using a mathematical formula. Is it really true? If so, Random isn't really random?? >>> More

I am trying to generate a good random seed for a psudo-random number generator. I thought I'd get the expert's opinions. let me know if this is a bad way of doing it or if there are much better ways. #include <iostream> #include <cstdlib> #include <fstream> #include <ctime> unsigned… >>> More
