 | Here's a hands on example. (A good reference to look at first:) http://stackoverflow.com/questions/1395591/what-is-exactly-the-base-pointer-and-stack-pointer-to-what-do-they-point I modified the C code a little: int foo=1; int main(int argumentCount, char *arguments[]) { const char* bar = "Hello, Daniweb!"; char *firstArg; int num; num=1; num=argumentCount; num=0; firstArg=arguments[1]; firstArg=(char *)0; return num; } I compiled using … |

| | The h after the number means that's it's in hexadecimal. Hexadecimal numbers run from 0-9A-F. Each digit is multiplied by a power of 16. So 57h is 5 * 16^1 + 7 * 16^0. You can also use the **0x** prefix to denote hexadecimal. So 57h is the same as … |

| | Re: Snake movement OK, your paradigm needs a little work. Three things I see. 1. What you're doing is you're **getch()**-ing every time you loop. **Getch()** is a show-stopper. The program won't continue until it has that key press. This won't work for an action game. You need to preface the getch with … |
