 | Re: Dubbuging >Does this meen that I will change this later when the application is finished ? Yes and no. When you run your application outside of the debugger (assuming you're using an IDE), a relative path will probably use the current working directory to look for files. Assuming you can make … |
 | Re: code >how can I make the last code shorter and more clear . I'd say it's plenty clear, and the only easy way to make it shorter is to drop the switch statement in favor of something like this: [code=cplusplus] // Find the display index of the selected column col = …  |

| | I'd suggest always surrounding blocks with braces until you understand the rules. Properly indenting your code according to how your compiler sees things would produce this: [code=cplusplus] if(choiceMenuInput==1) input(); else if(choiceMenuInput==2) return 0; else printf("\n\n\n\n\n ERROR YOU HAVE ENTERED A WRONG CHOICE\n\n\n"); system("pause"); inputedit(); [/code] The last two lines are … |
| | >But what about the newlines and/or tabs? Indeed. And what about such monstrosities as "\t \n\n\t"? Does "extra whitespace" refer to adjacent whitespace characters of the same value, any value that isspace returns true for, or are we only working with the ' ' character? The problem doesn't seem to … |
| | The easiest way is to block for input using [ICODE]cin.get();[/ICODE]. However, that only works if there isn't anything left in the stream, which in this case is likely to happen. Change your code to this: [code=cplusplus] #include <iostream> int main() { std::cout << "Enter two numbers:" << std::endl; int v1, … |
| | Re: Need help. >is there a quicker way to fill the list with A,B,C,...,Y,Z whithout doing all this? Yes, put your code to add a new node into a function, then use a loop: [code=cplusplus] int main() { struct node *current = 0; const char *alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"; for ( int i = … |
| | >No, not currently, although you can see more in your >member control panel than is public in your profile. Is there any reason for that? I see rep as completely pointless except for the comments, which I enjoy reading. It would be nice if there could be a link to … |
| | >I'm trying to make a program that converts octal numbers to decimal numbers. I don't suppose this would work for you: [code=c] #include <stdio.h> int main ( void ) { int number; scanf ( "%o", &number ); printf ( "%d\n", number ); return 0; } [/code] |
| | >cin.get(sex); This only reads one of the two characters that are in the stream. The second character is '\n'. Conveniently enough, getline uses '\n' as a delimiter, so it's terminating successfully right away rather than blocking for input.

| | >Ho can I get around this? You'll have to learn about working with multiple threads or multiple processes. That's a rather broad and complicated topic for a forum post though, try google. |
| | A stringstream is still a stream, you can't just copy a stream as std::vector does for its elements. Try using a pointer/smart pointer if you really want a vector of stringstreams. |
| | >vector<string> vect; >copy( istream_iterator<string>(is) , istream_iterator<string>() , vect.begin() ); The vector is empty, and copy won't call push_back for you. You need to add a back_inserter to the destination or copy will write to memory that you don't own: [code=cplusplus] copy( istream_iterator<string>(is) , istream_iterator<string>() , back_inserter( vect ) ); [/code] … |
| | Re: about accessing >i want to access the addresses other than provided to me c compiler I'll guess that you mean you want to access arbitrary memory addresses. C allows it, but a system with protected memory isn't likely to be happy if you try it: [code=c] #include <stdio.h> int main ( void … |

You're only inserting into the table if the item already exists? :confused: I think you should avoid that confusion altogether and just hash straight from the insert function. >if(find(newItem)!= -1)// call to find index exist >hashVal = find(newItem);// know the position or hash That's … |

| | >can anybody help me with this? When someone says "can you help?" and only posts an assignment, we tend to assume that they want us to write it for them. Perhaps you should also post the code you've got, and if you don't have any code, try [B]something[/B] before asking … |

| | Re: sudoku This is a forum in which you can get help for writing your own code, not a service that provides code to you. |

| | How about posting actual code so we know what advice to give you. :icon_rolleyes: >corr[8]="pizzaboy"; error-- cannot convert char* to char Presumably corr is declared as [ICODE]char corr[N];[/ICODE], which means that corr[8] has type char, not char*. >corr[]="pizzaboy"; error-- char has zero values Presumably this isn't a declaration. >corr[2]="z" ----- …  |
 | I don't like your options. "good enough" rarely is, and perfection is usually a pipe dream. How about "good enough" versus doing it right? In that case I'd pick doing it right regardless of the time frame.  |

| | >the stuff you can do in C can be done in C++, except build an O/S. Nope, you can do that in C++ too. C++ can be used anywhere C can, provided there's a compiler available for the target machine. |

You're basically writing an odometer where the characters on each wheel are specified by the first input string and the both the number of wheels and starting combination are specified by the second input.
