 | [quote] i have to read each line and then copy to a variable.[/quote] Perhaps strtok() may not be the best way to handle this situation (although I guess it can be used using the '\n' newline escape character as a delimeter); however, your goal seems to be to read in … |

| | Why are you returning 0 from your 'else' conditions..?? why not let processing continue throughout the loop? Stuff like this can cause your program to not work the way you think it will work. |

| | Is formating your hard disk and re-installing an operating system an option for you? |
| | I guess you can only compare what you have... right? Therefore, list traversal w/ comparison should only be as long as your shortest list. Another option could be to populate the shortest list with a sentinal value so that both lists would be of the same length.  |
| | Your professor says you have to accept user input as a floating point number, but he has no requirement for storing the variable as a float; therefore, I would simply accept all user input into a c-string (char array) and perform your validation. The following code uses isdigit() from the … |
| | Re: I need help :( Your professor gave you a function free of charge called outtextxy( ). Worst case scenario, why not just call outtextxy() individually for every ascii character that you will to output on the dos console to draw your circle? This may seem inefficient, but here is a way to at least … |

| | Re: Unique ID are there any guarantees that any id you come up with will unique.. if so, how will you make this determination... |
| | I would use C++ to create an 'array of structs'; each struct should contain attributes for class name and for class number. Then create an array of appropriate size of the aforementioned struct object. Populate the array by prompting for user input. |

 | When it comes to storing a bunch of records, nothing beats what I like to call an 'array of structs'. First, design a container that you would like to use: [code] stuct record{ string id; string name; double price; int quantity; };[/code] Now that you have a good design for … |

| | Re: using 'while' The use of a loop may not be warranted in this situation. It seems to me the code is procedurally linear; get user input, perform error checking, test user input, provide output with correct answer. Using a loop, whether it be while, do/while, or for is usually implemented when several … |
| | Here is a good tutorial on using strtok(), it's written in C, but that's what you get for using c-strings teehee [url]http://cboard.cprogramming.com/cplusplus-programming/60924-cstring-algorithm-what-do-you-think.html[/url] it offers this example: [code] /* strtok example */ #include <stdio.h> #include <string.h> int main () { char str[] ="- This, a sample string."; char * pch; printf … |

| | I'm not sure of the relevance of Python in today's modern IT world.. but my advice is to spend at some time and do a local job search for software engineers. In my experience, most companies want software engineers that are good in all areas: website design, databases, C, C++, … |

| | Re: Sorting I would use c++ to prompt the user for 10 integers. Each entry could be stored in an array of integers. At this point, you could display a menu of options on how the user would like to sort the array; which sorting method to use, and to sort either … |
| | Are you feeling lucky... I'm gonna go all-in on this; I've written a few ascii table games so I know what ye' are talking aboot here. There are of course many ways to do this. I would suggest to write specific functions to test every possible winning situation that can … |
| | I would use c++ to design a menu type structure. You should display a menu using iostream objects, such as cout. After your menu is displayed, you should prompt the user for a menu choice. One structure in mind that lends itself to handling menus is use of the switch( … |
 | Now that you are using <string> class objects, it is time to unlock the magic of the almighty string. Here is a list of string object members: [url]http://www.cplusplus.com/reference/string/string/[/url] On of them that you may find of particular interest is the find( ) function, which will return the element position of … |

| | Luckily for you, the c++ standard provides you with the tools necessary to open, read, and write to files. You can use these tools by including the <fstream> library. Then you can create ifstream objects that will allow you to open and read from a file, and ofstream objects that … |

| | If you think about it, any multi-demensional array is in essence a 1D array.. If you have ever studied assembly language you would know this is true. My opinion would be to just keep your 3D array, and access everything through a 1D array subscript. You could access every element … |
