[B]>how to compile c++ program when we r using two different functions which are defined in different file(s) under same directory in linux gcc???[/B] First look at Sky Diploma's post. Second: Well, I would type: [ICODE][B]g++[/B] -o [I]outputfile[/I] [I]file1.cpp[/I] [ [I]file2.cpp[/I] ] [ file[I]x[/I].cpp ][/ICODE] The square brackets indicate an …

Well, you could try using the derived maths functions: [LIST] [*][TEX]\sin^{-1}x = atan(\frac{x}{\sqrt{1-x^{2}}})[/TEX] [*][TEX]\cos^{-1}x = 2 * atan(1) - atan(\frac{x}{\sqrt{1-x^{2}}})[/TEX] [/LIST] :) Edit:: Sorry jephthah, I didn't read your post carefully :(

[CODE] #include "fstream" #include "iostream" [/CODE] has to be: [CODE] #include <fstream> #include <iostream> [/CODE] Edit:: Why are you using a preprocessor macro? [B]typedef[/B] would be a more accepted way :) Edit:: OP edited/clarified his post, so I removed some things from mine as well :P

[B]>The type of the array is int, so the size of the array is 10 * 4.[/B] To the OP: Yes, on most implementations, this is the case, but certainly not on all. In that example you assume that an integer is 4 bytes. You can get the exact size, …

Hi [B]linkingeek[/B], welcome to this forum. Could you please [URL="http://www.daniweb.com/forums/announcement8-3.html"]post using code tags[/URL]? This makes the code much more readable.

Well, my first remark is that you don't have to call a destructor explicitly, it will be automatically called when the object goes out-of-scope (this is for example when you shut down your program), so don't write: [ICODE]~Question();[/ICODE] anywhere in your code. Edit:: ^^ Actually this is just giving a …

To the OP: Don't write your code like this: [ICODE]while(os.eof())[/ICODE], instead write it like jencas did. Want to know why? Do a forum search on: feof or eof :) Edit:: I thought it was safely to assume that the 'oef' in 'os.oef()' is a typo he made.

iostream objects are usually slower than printf, but the little efficiency you gain by using printf is not worth avoiding the flexibility of the iostream classes. (remember: iostream is not only cout, cin.)

If you specify [B]%d[/B] in the format string of the [B]printf()[/B] function, you also have to specify a corresponding integer value to print. [U]General rule:[/U] For each format specifier you include in the format string, you also have to supply a corresponding value (of the same type as the format …

Yes, change [ICODE]#include <iostream.h>[/ICODE] to [ICODE]#include <iostream>[/ICODE] and put the instruction using namespace at the top of your code or use the [ICODE]std::[/ICODE] specifier for each object (in namespace std) you want to use :) ...

When running this code, variable [B]w[/B] contains an unknown value, this will nearly always cause an array override (unless you've much much luck).

To generate an executable you should 'Build' it, compiling is not enough. If you've compiled it, you still have to 'link' it to an executable file. The 'Build' menu command will do these things both: it first compiles your source, and thereafter it links your compiled object file to an …

I'll give you a small start: (assume [B]number[/B] is an integer variable) A number is odd when the modulus is not equal to 0. For example: [CODE=cplusplus] if( number % 2 ) { // The number is odd } else { // The number is even } [/CODE] BTW, What …

It's not recommended to just program it like that because you return a pointer to a local (automatic) variable, and when the function returns, the variable will be 'destroyed' (this means: it doesn't exist anymore, the memory assigned to it will be marked: "allowed to use"), but you still have …
