 | look in your compiler's limits.h header file. You will find them all there. >and anything bigger than that? That doesn't make any sense. What do you mean by "bigger than that"? >And also how to calculate this? How to calculate what? sizeof(object) returns the number of bytes required to store …  |
| | Line 23: what exactly does sizeof(buf) return? Answer: check line 10 and you will see buf is declared as 1024 pointers, so sizeof(buf) is 1024 \* sizeof(char\*). Assuming sizeof(char\*) == 4 (which it does on MS-Windows and \*nix) sizeof(buf) = 1024 \* 4 = 4096. From briefly reading some of …  |
 | [QUOTE=fzafarani;432095]Yes, I want to write my own C++ compiler [/QUOTE] Good luck :) Unless you have a Ph.D. in computer science and mathametics plan to spend the next 20 or so years writing it.  |
| | You can easily skip the first line by calling fgets() to read it, then just don't use what was read. Do any of the strings contain spaces? fscanf with %s can't read the spaces. If there are no spaces with the strings then the fscanf line you posted will probably … |

| | a+b adds the two ascii values. Look at [any ascii table](http://www.asciitable.com/) and you will see that 'a' == 97 and 'b' == 98, so a+b = 97+98 = 195. Now look again at that ascii table and find the character whose ascii value is 195. What you want to do … |
 | Other than poor formating, I don't see anything wrong with how you allocated the array. The values in the array are something else. void John_is_3D(int dimx, int dimy, int dimz) { int ***John; // pointer to pointer to pointer John = new int**[dimx]; // array of pointers to pointers for … |

| | To delete the inner list just iterate through the list and delete each node one at a time, something like this: It assumes head->item_data pointer is NOT NULL, so you should probably test for that before executing any of the code in this function. void DeleItemList(struct client* head) { struct … |
| | Do you have antivirus running on all PCs? Have you checked them for malware? |
 | line 5 is wrong -- notename[x] is a single character and c_str() returns a string. Maybe line 1 is incorrect -- `string notename[10];` which would mean notename is an array of string objects. string notename = "filename.txt"; x = 1; cout << notename << endl; if(remove(notename.c_str()) != 0) { perror( … |
 | I would be very surprised if you found any language translator that did the job 100% correct -- the .NET functions would be easy, but the rest nearly impossible due to differences in the two languages.  |
| | Re: class help create another class for those two then you can make an array of that class. See the examples posted in your other thread. |
| | Re: help in arrays If you have not yet studied structures then declare two arrays, one for 10 student names and the other for the sections. This assumes the names book1, book2, etc never change, so there's no point in storing those strings. If, however, those names can be different for each student then …  |
| | Re: loto game what exactly is your question(s) about how to write that program. You will need to use functions srand() and rand() which generates the random numbers, then save the values in an array. Each time a new random number is generated search the array to see if it's already there. If … |

 | The only time I have found recursion useful is when transversing the file system, such as in [this](http://www.daniweb.com/software-development/cpp/code/216812/searching-linux-directories) code snippet. Otherwise I try to avoid it, mainly because many years ago recursion was just too expensive in terms of memory and time. I know those aren't as critical any more … |

| | what is inarray()? You have too much duplicate code in that function. This is the recommended way to write such functions, not that it does not call feof() at all, but relies on fgets to return NULL then end-of-file is reached. else { while(fgets(word1, 30, fileIn) != NULL) { //succeeding … |

 | r/1200 is doing integer math which means all decimals are discarded. So 10/100 is 0 because 10 cannot be divided by 100. You can fix that in one of three ways (1) Declare r as float instead of int, then use scanf("%f") instead of scanf("%d") (2) Typecast either the numerator … |
| | maximum is the size of the screen and its resolution, usually 25 x 80. The 35X25 was common when PCs first came out in the early 1980s. But MS-Windows console screens have much smaller fonts and more rows. |
| | For numbers you have to do a little more processing -- convert the ascii value of the char to binary then add it to an integer. This works for English language and standard ascii character set. I have no idea what you intend to do with the number, but whatever … |

Christmas didn't become a federal holiday in America until 1870. I anticipate one day in the not-too-distant future Congress will pass a law abolishing it as … |
