| | It should exchange the value of the two variable parameters. The two parameters are [URL="http://www.brpreiss.com/books/opus4/html/page593.html"]passed by reference[/URL] so that swap() can change them and the calling function will see the change. |
 | Re: string program line 9: string stop, flavor, count = 0 count is a string, so why are you setting it to 0 like it is an integer? I suspect you want this: [icode]int count = 0;[/icode] line 26: >> if (flavor = 'STOP' || 'stop') strings have to be enlosed in double … |
| | Re: Linked List 1) remove conio.h -- its non'standard and not implemented by very many compilers. Code snippets should not use compiler-specific stuff. 2) delete all those global variables on lines 12 and 13. Just declare them inside the functions that use them. And you will probably have to pass the std* head … |
| | where is your code? No one here will write that program for you. |

| | >>The program is supposed to take in a file provided through standard input That means get the name of the file from standard input, not the lines of the file. You have to open the file and read each word, something like this: [code] int main(int argc, char* argv[]) { … |
| | You don't have to store all the lines, just the two lines that you want to compare. Sequentially read the file, counting lines as you go along then save only the two lines you want to compare. |

| | Re: Arrays_Grade Why did you make grades a double instead of an integer? doubles are not necessary in your program because nobody will have a grade of something like 75.123 (at least I never heard of such a thing). First thing is to make a function that takes two arrays as arguments … |

| | If you use string, then use find() to locate the space, and substr() to extract the characters from position 0 to the location returned by find(). |
| | >>The program was initially written in VC++ VC++ is not a computer language. Its an IDE/compiler. So saying you are converting from vc++ to c++ is nonsense. |

| | Modern 32-bit compilers to not support that header file because it was intended for 16-bit MS-DOS 6.X and earlier operating systems. The alternative is to use win32 api functions OpenFile() to open a comm port, ReadFile() and WriteFile() to read/write to it.

| | Its not working because thread functions must be either static alss members or functions outside any class. Address of a non-static class method can not be passed to any win32 api function. Make StartThread() static and the compiler will probably take it. |
| | Can not be done because MFC will not give you what much control over it. All the text in the edit control is displayed in the same color. You can't use html in any mfc control. |
| | >>_CRTIMP FILE* __cdecl fopen (const char*, const char*); The above is a function prototype. It has an open parentheses '(' and close parentheses ')' with or without arguments between the parentheses. |
| | >> int numbers[ARRAY_SIZE]; {10,20,30,40,50,60,70,80,90,100} That is incorrect. Here is what you want[icode] int numbers[ARRAY_SIZE] = {10,20,30,40,50,60,70,80,90,100};[/icode] The index number is nothing more than the loop counter. Therefore you can delete the line [icode]for( index=0;index<20;index++) [/icode] then cout the value of count instead of index. |

| | you can not use inport and outpout with any 32-bit or 64-bit compiler. Those functions are no longer supported by the operating system. On MS-Windows you will have to use win32 api functions, starting with OpenFile() to open the com port, ReadFile() to read from it, and WriteFile() to write … |

| | you want to use the substr() method, not erase(). And delete line 8 because length isn't needed (unless you want to use it somewhere else). [code] string type = temp.substr(0, pos); string value = temp.substr(pos+1); [/code] |
| | First you have to get a list of all the files in the folder ( see FindFirst() and FindNext() win32 api functions). Then for each of those call _stat() to get the file creation date and compare that with today's date. Finally, use remove() to delete the file. Where should … |
| | C/C++ use "libraries", and "dll"s (MS-Windows) not packages. How to create one depends on the compiler you are using. Normally the source code for a library is all in one folder, and it doesn't matter what the folder name is as long as your compiler knows. |
