I have a couple of questions from a beginner. If a program compiles correctly in VS, will it compile correctly in g++(GCC) ... s 10, will it compile correctly on Linux? Is it possible to check whether the program will compile in Linux and in g++(GCC)?

For example, there is a C code: static int add(a, b) { return a + b; } How do I compile this code into a binary file that will be executed from the beginning of the file byte by byte?

A static array with a size not known at the time of compilation. char buf[atoi(argv[2])]; And where can I read about it?

There is a task-to write a program from two modules: one in C, the second in assembly language. All sources unanimously state ... n KUbuntu OS. Question: where does this first argument hide, and how do I finally get it out and return it to the C module?

I'll tell you right away - I'm a noob in C++, but I want to learn it. I'm trying to compile this code: #ifndef UNICODE #defi ... а: выполнение ld завершилось с кодом возврата 1 No matter how the code looks, it still doesn't want to compile. What to do?

The task is as follows: you need to ask the user for a word and display it on the screen in reverse. when I use this code: # ... { printf("%c", str[i]); } printf("\n"); return 0; } Then I get everything except the first character.

Good afternoon. I mostly use Visual Studio, and for some time now Visual Studio has been insisting with maniacal persistence ... b.com/online_c++_compiler Https://ideone.com/ Localtime_s doesn't work either. Even if you define all the specified macros.

Good afternoon. I mostly use Visual Studio, but sometimes I need the code to be translated under GCC. There are many onlin ... . So the question is: Tell me the online translators of GCC C++, in which you can broadcast multi-file projects. Thanks.

Why don't I have string s = GetString(); defined? Hell.c #include <stdio.h> #include <cs50.h> int main(void) { ... hell.c:(.text+0x16): undefined reference to `GetString' collect2: error: ld returned 1 exit status make: *** [hell] Error 1

I have a project where the header files are stored in the include folder, and the implementation files are in the src folder, ... ow did not understand why separately additional rules to the template work, and if they are generated automatically, then no?

To build a program that is statically linked to .however, the following command was sufficient: $(CC) bin\main.o -L.\bin -lc ... ed, right? Do I understand correctly that the file libtstdll.a can then be simply linked to the program without any -lmyldll?
