Hello All, I am trying to write a simple audit class that takes input via operator << and writes the audit after receiving a custom manipulator like this: class CAudit { public: //needs to be templated CAudit& operator << ( LPCSTR data ) { audittext << data; return *this; } //attempted manipulator s...
I've got a line of code that sets the fill value to a '-' character in my output, but need to reset the setfill flag to its default whitespace character. How do I do that? cout << setw(14) << " CHARGE/ROOM" << endl; cout << setfill('-') << setw(11) << '-' << " " << setw(15) << '-' << " " << setw(11) << '-' << endl; I thought this ...
Hi guys, I'm trying to implement my own stream manipulator inside my logging class. It's basically endline manipulator which changes state of a flag. However when I try to use it, I'll get: ftypes.cpp:57: error: no match for ‘operator<<’ in ‘log->Log::debug() << log->Log::endl’ /usr/lib/gcc/i386-redhat-linux/4.1.2/../../../../include/...
I want to define a class MyStream so that: MyStream myStream; myStream << 1 << 2 << 3 << std::endl << 5 << 6 << std::endl << 7 << 8 << std::endl; gives output [blah]123 [blah]56 [blah]78 Basically, I want a "[blah]" inserted at the front, then inserted after every non terminating std::endl ? The difficulty here is NOT the logic ma...
In my next project I will have to implement an automation solution to test a hardware device. basically, the test involves an industrial robotic arm picking a device to be tested, holding it at some specified position and then using a series of other devices like motors and sensors to exercise several areas of the product to be tested. ...
The little test program below prints out: And SS Number IS =3039 I would like the number to print out with padded left zeros such that the total length is 8. So: And SS Number IS =00003039 (notice the extra zeros left padded) And I would like to know how to do this using manipulators and a stringstream as shown below. Thank...
I have a class that is derived from ostream: class my_ostream: public std::ostream { // ... } I want to make a manipulator (for example do_something), that works specifically to this class, like this: my_ostream s; s << "some text" << do_something << "some more text"; I did the following: std::ostream &do_something(std::ostrea...
PSPS: (a Pre-scripted Post-script) It has just come to mind that a more prescient question would have included the notion of: Is this non-display of "0x"(showbase) for zero-value integers a standard behaviour, or is it just a quirk of my MinGW implementation? It all began on a pleasant Sunday morning... I want to dump some Handles i...
Is it possibile to ignore punctuacion using std manipulator on cin? For example suppose you have an input stream (in the actual case a file) like: "one, two three". I want to be able to do: f >> ignore_punct >> a; f >> ignore_punct >> b; f >> ignore_punct >> c; at the end a=="one", b=="two", c=="three". ...
