c++ lack jacks game for beginners in cmpsc 121
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.
For those not familiar with the game of BlackJack the purpose is to get as close to 21 as possible without going over and beating the dealer’s hand. The player gets two cards and the dealer gets one card. The player can take a hit and the dealer has to hit until above the total of 17. Below is the source code, but do not copy and paste this for any homework assignment. Use this code to get you going with your own project. HINT: create pseudo code then start coding from the outside in, like start with the player wanting to play again then the initial deal.
If you select all the code below and paste it into a C++ source file you will also get the code not visible on this page. Please take the time to check out some of my sponsors on the left.
