Files ending in C are source code files in the C programming language or C ++. C files can contain the source code for entire programs or even only parts, for example classes or functions, which are referenced in another C file, dH Inclusions (so-called includes)
c files are just text files that can be processed by a C or C ++ compiler. They can be opened and edited in any text editor, however it is recommended to use editors with developer functions such as syntax highlighting for easier work.
In principle, C files can be compiled in standard C with any C or C ++ compiler. H. Convert to an executable program. However, depending on the includes used (eg certain special libraries) compilation errors can occur, since these are not included in every compiler.
Some compilers use a (small) C for source code files in the C language and a (large) C for C ++ source code files. Furthermore, C ++ files are also often suffixed with c ++ or cpp.
