I am using borland turbo c++ version 4.5 and for printing a coloured output i used textcolor() but it is showing error that call the undefined function 'textcolor' in main, so what can i do now to print a coloured output???
View 1 RepliesI am having a world of problems of what i thought to be rather simple.
Edit1->Text = "123401278034987120478102873401982734";
Now Edit1->Text is an AnsiString
And I would like to format this to a number value, so that i can say.
CSpinEdit1->Value = "123401278034987120478102873401982734"
In other words transferring the value from Edit1->Text to CpinEdit1->Value;
Integers won't work because the number is to big. So i tried going from String to Number like in this article Converting numbers to strings and string - C++ Articles
But that won't work because its an Ansistring, how would i go about this conversion?
I have to write a program for school that displays a random sequence of colored squares, each square is a different color. Then the squares disappear and the 5 more pop up at the bottom. The user has to guess which color was first, second, and so on. They click on the squares on the bottom that matches the first square on the top.
My question is how do you get the computer to say ok this square (that the user clicked on) matches this square here.
is there a command that says something like if this color matches this color?
I am using default richeditctrl in richeditview. My requirement is that i want to show colored traces in every10 milliseconds.

Finally got to functions. Made a simple one that adds two numbers:
Code: int add(int a, int b){
cout<<"a+b=";
return a+b;
}
It refuses to give an output unless I use cout.
If I just call the function like so: "add(12, 24);", shouldn't it print out a+b=36? It only prints out "a+b=", unless I use "cout<<" ahead of the call.
My simple question is why does it need cout ahead of the call? Shouldn't "return" do its job and print out the number?
i just started learning programming and i just wanna know how come when i try to print the last digit of a number the output always become 6?

I wanted to take the averages of the whole week and output a print statement. I've tired few ways this like assigning "temp" a pointer, or in each if statement assigning temp to a new variable like a, b , c etc. Then adding them all up at the end and dividing by 7. My issue is I am unclear how to store the number typed for each if statement while the program is running, then have it compute the simple equation. The code in question is below:
Code:
#include <stdio.h>
int main(int argc, const char * argv[]) {
int i, j = 0, temp = 0;

I was recently introduced to the fstream header file. I want to know is their a easy way to print an output with append data in a .txt file.
And secondly I am also having an error with my header file. It says error: cannot open source file "fstring" when I hover my mouse over "#Include<fstring>".
How to make it so an output for a program would print out the string in reverse/backwards? I was just curious on how to do this.
View 6 Replies View RelatedI am creating a Matrix class, and one of the constructors parses a string into a matrix. However, printing the result of the constructor (this->Print()) prints what I expect, and an <object_just_created>.Print() call returns bogus data. How is this even possible?

I am/we developing in C and we have a number of different programs. We also have problem to keep track of different versions of a specific exe file.
Is there any way to add version number when build a file so the version is added in the properties.
I doing this in a MFC c++ project in a .rc file. Is there a way (or a similar way) of doing this in C? Here its stored in the details section with product version 6.0.8:
Just wondering if there was a standard way people add a version number to their c++ code? I can just define a variable or #define and write the version number to that, but wanted to know if there is a standard method people use?

When you are creating a project or program, how do you number your versions?
Like when you release it, it becomes v1.0, am i right?
then every release or build after that might become v1.1 or v1.0001 or v1.0.1.2
Is there a certain global system for how you Number your versions or is it just up to the developer?
I have been trying to compile a static version of the boost libraries, however when I try to launch the program it says fatal error LNK1104: cannot open file 'libboost_serialization-vc100-mt-s-1_53.lib'
I have checked in the boost/stage/lib folder and that file is not there. I compiled boost with b2 link=static yet the file still isn't there.

I have a set of projects. Each one builds either a static library or an executable. What I'd like to do, is at build time I want to embed a version string representing the version of the executable as well as the version of each library. These version strings will come from an external source (in my case it's based on a "git describe" call, but that's beside the point). Embedding such strings can be highly valuable for traceability. (Versions of 3rd-party libraries are not necessary.)
I'm using qmake as my build system, but this should work more or less similarly with any build tool. What I'd ideally like to do is define this process in such a self-contained way that a an absolutely minimal amount of additional code is required in order to leverage it. Preferably, nothing more than an include(version.pri) in each project's .pro file in order to collect the versions. (Retrieving them later, such as to respond to a --version command-line flag, can be done via traditional C++ methods.)
What I've done so far is to define a singleton VersionTracker class, and then tweak the build system so that "MODULE" and "VERSION" are preprocessor symbols defined at build time. I've also tweaked the build system so that a file in each project, version.cpp, is rebuilt (and regenerated if necessary) on every build regardless of changes. This source file can capture the information in the preprocessor symbols into each static library and the executable.
Now, here's the problem. How can I get the information from those version.cpp files into the VersionTracker class? I thought I could use a global object's constructor to do it, but it turns out the symbols are stripped out when the static libraries are linked so I only get the executable's version. I also found a page on stackoverflow detailing a very clever way to call a registration function at class definition time, but again the class definition appears to be stripped out if it's defined in the version.cpp file of a static library and not referenced elsewhere.
Everything I've read basically says you either need to use linker flags to prevent symbol stripping entirely, which is probably an adoption-killer for this hack, or you need to use an explicit registration function called from the executable. I'd prefer to avoid this since it is just another thing a programmer could forget to update when a library dependency is added or removed.
My last idea, which I haven't tried yet, would be to put each version.cpp into a separate static library from the one it is describing. This version-only library could be linked without symbol stripping. I don't love this concept but it might work.
I haven't yet figured out how shared libraries can be worked into this framework at all. I'll worry about that after I get static libraries working.
Is there a way I can extract Machine / Hardware ID and OS Version using VC++?

I have a program that is reading six characters from a text file, swapping every other character(ABCD would read BADC), and then adjusting their value based on a user's adjusted value input. If the adjusted value is 5 then letter A becomes F.
The final output line should print the initial six characters followed by the final six characters after the swap and encrypt adjustment.
I can only manage to print the final characters. Am I far off thinking I need to use pointers to point to the original character values?
