int main() { return 0; }

by team

 $ gcc -o пример пример.cc && ./пример

an error is displayed

What could be the problem?

    Or rename the file as an пример.c . I remind you:

    1. C-files by default have the extension .c .
    2. C ++ - the default files have the extension .cc , .cp , .cxx , .cpp , .c++ , .C .

    Variants of such perversions as compilation of GCC, and then linking G ++, are omitted. Another way is to use the -x option of the compiler, which specifies the language to be used.

    • .c and .C are the same in my opinion. - gammaker

      William von Hagen's The Definitive Guide to GCC says the following (my translation):> GCC compilers evaluate file name suffixes to determine the type of compiler used. Table 2-1 lists the suffixes related to g ++. >> Table 2-1 C ++ file name suffixes> .C - preprocessor processed C ++ code> .cc - preprocessor processed C ++ code (this is the standard extension for C ++ source code files)> .cpp - preprocessor processed C ++ code> .cxx - preprocessor-processed C ++ code> .ii - non-preprocessor C ++ code - northerner

    It is necessary so:

     $ g++ -o пример пример.cc && ./пример
