Files with the extension CPP are source code files in the programming language C ++. Cpp files can contain the source code for entire programs or even only parts, for example classes or functions, which are referenced in another CPP file, so called includes
CPP files are just text files that can be processed by a 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, CPP files can be compiled in standard C ++ with any 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.
C ++ source code files are also sometimes suffixed with c, which can lead to problems because the file extension c should actually be used for C source code files. By contrast, a CPP file is clearly a C ++ source code file.
Most often resolving problems with opening CPP files is very simple. Just install an appropriate program that supports such files. All of the listed programs support CPP files, but may vary in offered function and purpose. Some programs may be capable only of viewing contents of CPP files or offer file conversion options, but may not be capable of editing such files.
It is possible that although a compatible program has been installed on user’s system, it is not used by the system to open it. This may happen because no default application was associated with this type of files. To associate CPP files with given application, select "Open with" from drop-down menu (accessed by right-clicking on the file). Then select from the list the program or application you want to be used to open this type of file. If the Apple Xcode applications is not on the list, select "Browse" option in order to manually locate the directory where Apple Xcode has been installed.
Sometimes problems with opening CPP files may not lie with the application itself, but can arise due to other causes, such as:
