 | umm, so then what's wrong with [ICODE]char map[10][10];[/ICODE] ? |
| | you want to extract part of a string from within a string. the fact that this string is in a linked list is irrelevant. ask yourself the same question, but generalized: "[I]How do i pick part of the data from the [B]string[/B]? [/I]" example: [ICODE]strncpy(&origString[10], subString, 5);[/ICODE] will get bytes … |
| | Re: Please Help Me the problem is you've got that "return" statement right near the end of the "else if (i==4)" block. if you've returned from the function, neither "bzero" nor "fclose" will be called. this is the danger of putting returns in odd places. unless you have a real reason not to, like … |

 | [QUOTE=riahc3;1187009]I personally wanted to use getch and getche[/QUOTE] forget getch and getche ever existed. the need for unbuffered terminal input has become obviated since the widespread adoption of GUIs, like, about 15 to 20 years ago. or dont, and hobble yourself with reliance on non-standard, non-portable library functions that will … |
| | you're gonna have to give us some more to work with here. lets see this window that you created using C. post the code. preferrably you will use code tags and post code that compiles. |
 | i'm having a hard time following your question... what exactly are you trying to do? one thing you should know that will help you, is you don't need to cast each char as an int just to do a comparison to a constant value. a char type is essentially just …  |

| | what Banfa said about your character array's size and the number of characters read by fgets() must match. but you don't necessarily have to allocate your "numbers" array dynamically. you can, for simplicity's sake, just declare it to be some arbitrarily large size. [code]double numbers[100];[/code] since these are "doubles" (double …  |

| | Re: RPN inputter these are warnings, not errors. meaning your program will compile and run (for a while), but probably will not work as expected because you're doing something unusual. first one is you're assigning an int (length) to the char array (input_buffer). before we can fix it, we've got to know what … |

[code] char buffer[32]; int number; do { printf("enter integer : "); fflush(stdout); // needed because no newline char fgets(buffer, sizeof(buffer), stdin); // get string input number = atoi(buffer); // converts integer found in string if (number == …  |
| | Re: winbgim help sorry you're having so much trouble. i'm afraid i have no idea about converting old borland graphics libraries. i avoid ever using them in the first place. at leas this can serve as a warning to others, to stay clear of developing on Turbo C, especially with the antiquated graphics … |
| | changing color of text is not a C-language function. if the Intel Compiler has this capability, it is a "compiler extension". you will have to find the documentation for the compiler and research how this is accomplished. be advised that any solution you find will not be portable, and will … |

| | dont use [B]float[/B] do use [B]double[/B] if you want to round up to the next single unit (one's place), then just add 1.0 and recast it as an int to drop the fractional parts. if you want to round up at a certain decimal place, then first multiply by a … |
| | [ICODE]for (;;)[/ICODE] just means "forever". typically used for a loop that will execute an indeterminate number of times, exiting with a [ICODE]break;[/ICODE] command once the exit condition is found. the corresponding while would be [ICODE]while(1)[/ICODE] or [ICODE]while(TRUE)[/ICODE]... doesnt make any sense to use '\n', even though technically '\n' is non-zero … |

| | you can copy any file, whatever the type or extension. just open the source file as a binary file and use a while loop to copy each byte one at a time to the destination, until the EOF charater is found. see [URL="http://www.cplusplus.com/reference/clibrary/cstdio/fopen"]fopen()[/URL],[URL="http://www.cplusplus.com/reference/clibrary/cstdio/fgetc"] fgetc()[/URL], [URL="http://www.cplusplus.com/reference/clibrary/cstdio/fputc"]fputc()[/URL], and[URL="http://www.cplusplus.com/reference/clibrary/cstdio/feof"] feof()[/URL] in the standard … |

| | gcc supports an extended precison "long double" type typically 10 or 12 bytes but Windows XP always maps the "long double" to the standard double (typically 8 bytes) MinGW on windows XP thinks it has a 12-byte "long double" but in fact it only has the 8 byte support on …  |

| | use fgets to read the source file one line at a time. this will take a small character array of some arbitrary length. say 80 or 120 characters. you could do it a lot smaller, but i don't see any reason why you would want to.. use fprintf to write … |

| | ncurses is the unix counterpart to DOS's conio. they both originated in the early 1980's. I beleive conio was basically a windows port of pcurses. they both are largely obsolete. ncurses does not do graphics any more than conio does. use GTK+ or OpenGL libraries for graphics. |
