 | you can not use switch with strings. >>word = getchar(); Don't use getchar() is c+++ programs. use cin.get() instead.  |
 | My first program in 1979 was in HP Basic on a HP computer that had a wapping 64K memory and used 8 Inch (203 mm) diameter glass diskettes to store data. A couple years later we also got a TI 99 programmable calculator that was pretty nice for the time. |
| | >>where can i get STL string user guide [URL="http://www.cppreference.com/cppstring/index.html"]here[/URL] use transform() to convert a string to upper or lower case, like this: [code] #include <algorithm> #include <string> <snip> std::string str = "Hello World"; std::transform(str.begin(), str.end(), str.begin(), ::toupper); [/code]  |
| | Re: quick question >>How may I clear whole array in that example code a constructor and use memset() to clear it. Line 3: conio.h is non-standard file that contains non-standard functions. You don't need it in the code you posted because there are c++ alternatives that are standard -- such as cin.ignore(). |
| | >>what do you think will happen to the values of x, y and z? why don't you just compile and run the program then you can find out for yourself instead of guessing. |
| | It might also depend on how the compiler implemented cout. Microsoft compilers cout is just a thin wrapper for printf(), that is, both cout and printf() call the win32 api function WriteFile(). I have no idea how *nix compilers implement the two functions.  |
 | can't you just translate that shell program into c? That is, write a c program that makes the same system calls ?  |

| | 1. Just parse the string. If you already know the time format then it is not very difficult to split the string into its individual parts (hours, minutes, seconds, milliseconds). 2. The milliseconds is not very useful when the time difference is greater than probably one minute. If the difference … |
| | My guess is that you do not have the list of directories set up correctly in the compiler IDE. Look at menu Tools --> Options --> Project and Solutions --> C++ Directories and make sure the path to the include directories are correct and includes the path to where you … |
| | Re: Excel and C++ Yes, and its very very complicated. I doubt you will gain anything by doing that, but will probably slow down the program even more because you are adding yet another layer. Probably C# or VBA would be better languages for that. |
| | I think you have to compile the boost libraries before you can use any of them. Did you read the readme and install files? |

| | Lines 1 and 2 only allocate one char of memory. Any attempt to use strcpy() on either pointer will normally cause memory corruption because strcpy() adds a '\0' to the end of the string that it copies. Line 4 will most definitely corrupt memory because you told getline() to accept …  |

| | Re: what is wrong line 2 in your first code snippet: use the boolean == operator instead of the assignment = operator. lines 4-7 -- you need to use braces "='{' and '}' in order to put lines 5-7 inside the else block on line 4. In the second code snippet its difficult to … |
 | The default class constructor is always called then the c++ class object is declared (except as noted below), for example on line 25 of the code you posted. On line 29 the class's operator= method is called, not the class constructor. The second example you posted works the same way …  |
| | The function that is being called requires wchar_t* instead of char* when compiling a program for UNICODE. Typecasting will not make the conversion.

 | The CWinApp-derived class contains a list of CDocTemplate objects. You can iterate through that to find the pointer to CDocument class. From CDocument iterate through the list of CView classes that are attached to the document. I know this seems a long way around to get to the CView class … |
