 | [QUOTE=Mr Gates]Ebil cscgal :twisted: Anyway, how would I do that so it deleted the file at closing?[/QUOTE] you can register a function that will be called when the program terminates with the atexit() function. this func could tehn call remove() on the file. |

| | Re: C++ Address Book it is faster to type but there's no difference in the code generated, test it and see for yourself. |
| | u are almost there. the scanf function returns teh number of correctly read variables. in your while loop, u are testing: [color=#000000][color=#007700] while (([/color][color=#0000bb]amt [/color][color=#007700]<= (float) [/color][color=#0000bb]100[/color][color=#007700]) && ([/color][color=#0000bb]correctItemsRead [/color][color=#007700]== [/color][color=#0000bb]1[/color][color=#007700])); but actually it should be: [/color][/color][color=#000000][color=#007700] while (([/color][color=#0000bb]amt [/color][color=#007700]<= (float) [/color][color=#0000bb]100[/color][color=#007700]) && ([/color][color=#0000bb]correctItemsRead [/color][color=#007700]!= [/color][color=#0000bb]1[/color][color=#007700])); when it returns 1, … |
| | Re: Tic-Tac-Toe agreed, it is always a good habit to get into. the only time u will see good programmers avoiding the practice is when writing kernel code - when every instruction counts, and then it is ur responsibility to be absolutely positive to double check that every variable is not used … |

 | i'm not sure if this is the answer u want, b/c i dont fully understand what u mean by "log window", but if u run a program from DOS prompt like: ./program >outfile standard output is redirected to the file outfile. if u want to do that inside the program, … |
| | Re: C++ graphics you need to learn a lot more to use graphics. most windows apps use the win32 API to display windows/pics/etc.. here is a tutorial bout it tho: [url]http://www.relisoft.com/win32/winnie.html[/url]  |
| | in 99.99% of cases it is much better to learn to write code that your compiler can optimize well. ie, compiling and observering generated code, and trying to fix your C to generate the proper asm. asm resources: [url]http://cs.smith.edu/~thiebaut/ArtOfAssembly/artofasm.html[/url] [url]http://www.geocities.com/SiliconValley/Lab/1563/assembly.html[/url] in short, on IA-32, registers eax, ecx, edx are called … |

| | Re: C craps game a test plan is designed to test the robustness of your program. if you are taking in any input from the user, you would want to try many values for those inputs. most importantly, u would want to try values that a "nice" user wouldn't give u. for example, would … |
 | yea, that's what apache does. what exactly are u trying to do here? |
| | if it returns void, then you can't use the return value b/c there isn't one! you are trying to "cout << Calc()" , that means print out the return value of function Calc(), but it has no return value since the return type is void. |
| | you're better off using the STL if you can, their algorithms are far superior to what most of us could write. |
