Linux, CentOS, Redhat G++ compiler and rand() / random function

Tuesday, November 18th, 2014

If you are using the G++ compiler in Linux, CentOS, or Redhat there are a couple of steps to adding a random number generator to any project.

  1. Include the precompile library: #include <stdlib.h>
  2. Use the function and add seeding: first_number = rand()%6 +1);

The basic function in C++ for the G++ compiler in Linux looks like this:

#include <iostream>

#include <stdlib.h>

int main()

{

int first_number = rand()%6 +1;

std::cout << first_number;

return (0);

}

c++ lack jacks game for beginners in cmpsc 121

Tuesday, October 1st, 2013

This is a beginners game of lackjacks that does not use any functions, arrays, or pointers. This is an excellent project to get to know the basics of C++ since you will be using variables, conditional statements, loops, and basic console I/O (input/output). This is a Windows 32 bit console application, so you should be able to paste this code into a blank project that you added a source page.
