Dev-C++ is a C/C++ integrated development environment (IDE) in Windows environment. It is a free software, and the source code is distributed according to the GPL license agreement. It collects a lot of free software, such as MinGW, and can get the latest versions of various tools that support it, and all this work is done by enthusiasts from all over the world. Dev-C++ is the designated tool for competitions such as NOI and NOIP, but the disadvantage is that the debugging function is weak. Because the original development company stopped developing after developing 4.9.9.2, it is now being updated and developed by other companies, but all of them are based on the latest version of 4.9.9.2.dev-C++:5.11.
