 | Re: VC++ To BCB 1. Just attach the file to your post here. Nobody will download that file for fear it might contain viruses or worms. 2. Why don't you translate it yourself. |
| | It is compiler dependent. Some compilers might define DEBUG, others _DEBUG, and still others might not define it at all. IMHO the best way to do it is to define the macro yourself in command-line options, such as -DDEBUG. |
| | delete that while loop -- no loop is necessary with the code you wrote because it reads and writes the entire file in one big swoop. That isn't practical for large files, but ok for fairly small ones. And you need to open both files in binary mode -- just … |
| | line 4: move it up above liine 1 line 13: for (int Hour=1; Hour <= 24; Hour++) That is wrong. Arrays are numbered from 0 to (and including) 23, so it should be written like this: [icode]for (int Hour=0; Hour < 24; Hour++)[/icode] line 15: Emp = Cust/20 + 3; … |

| | read the two files into memory then call memcmp() to compare them. Or, if MS-Windows, use the COMP program (create a command window, then type [icode]c:>Help <Return>[/icode] and view the available commands.  |
| | Probably your compiler because it worked ok for me after correcting the header files as previously explained. |
| | Re: why not an error [QUOTE=jephthah;882237] but the memory has not been [B]allocated[/B], so if you try to modify it the resulting behaviour is undefined. .[/QUOTE] The problem is NOT that memory was not allocated for the string (actually it was), but that the string resides in (probably) read-only memory, depending on how the compiler … |
| | You might want to put code guards in that header file to prevent the problem you describe. [code] #ifndef POINTS_H #define POINTS_H struct Points { int xCoordinate; int yCoordinate; int zCoordinate; }; // end of struct Points definition #endif [/code]  |
| | you need to allocate one more byte than file size for the string's null-terminator, then add the null terminator after the read() operation. [code] char* data_block=new char[(int)size+1]; file.seekg(0,ios.beg); file.read(data_block,size); data_block[size] = 0; file.close(); [/code] |

| | I assume you want to pass the entire array to that function, then don't specify the array size. I'd also pass the element number that you want used in the sprintf() call. [code] void DisplayPoints(Point point[], int index){ sprintf(xCoordinateText,"%.0f", point[index].xCoordinate); BasicFunctionsCode.render2DBitmapText(1080, 100, font, xCoordinateText); } // end of DisplayPoints [/code] |
| | You can execute another program on PPC the same way you do it on a PC. CreateProcess() win32 api is one way. Remember, PPC does NOT have a command prompt, so system() is not available (as I recall). There is also no such concept as [b]current working directory[/b] or [b]change … |

| | [code] for ( int i=0;i<row;i++ ) { if (custn == customers[i].custno) { <snip> } else errorMsg("Invalid Option"); } [/code] It would appear the logic is wrong. Unless the very first item in the array is always the custn its looking for then the program will always display the error message. |

| | why did you bother creating that pointer just to pass to a function? All you have to do is pass string's c_str() [icode]WriteFile(str.c_str());[/icode] >>line #9: cin.widen('\n') What is that supposed to do -- unless you compile for UNICODE it will do nothing. Seems more reasonable to just do this: [icode]getline … |
| | lines 13-40 do the same thing over and over for 81 times!:icon_eek: What's the point of doing that? delete line 12 because lines 13-40 initialize the array with other numbers. lines 61 and 64: what is [b]comp false;[/b] ? There is no such thing as [b]comp[/b] |
| | Stay away from those pointers. lines 8-10: delete those lines lines 16-18: [code] p.push_back(string("s1")) ; p.push_back(string("s2")) ; p.push_back(string("s3")) ; [/code] With the above changes you don't have to worry about a destructor because the vector and string classes with destroy themselves. |

| | variable [b]password[/b] is only a single character, which means it will accept only one character. If you want it to accept many more characters then declare it as an array of characters, or a std::string object, like this: [icode]char password[255] = {0};[/icode]. That lets you type up to 254 characters …  |

| | line 6 is unnecessary. you are not null-terminating the destination string. wcslen() returns the number of characters in the string and does not include the null terminator. So add a line after line 10 to null terminate the destination string. You could also have just used wcscpy() and not bother … |
