Reasons and solutions for CodeBlocks unable to run exe files

When double-clicking the exe file generated on Codeblocks, an error (0xc000007b) that cannot run sometimes occurs

Straight to the point, this is most likely due to the inclusion of iostream in the header file.

Let's take the simplest helloworld program as an example. When the header file uses stdio.h (test1.cpp), the program can run on codeblocks, and there is no problem with double-clicking the generated exe file.

But if you change stdio.h to iostream(test2.cpp), although it can run normally on codeblocks, the exe file cannot be opened

The reason for this error is that the dll dependencies cannot be found, so I used the dumpbin tool of VS to view the dependencies of the exe file.

It can be seen that test2 has one more dependency called libstdc++-6.dll than test1, and further solutions can be referred to.

Since the school homework required uploading executable exe files, when I encountered this error at the beginning, I always thought that there was a problem when I introduced the third-party library dll (the computer did not directly tell me which dll failed to find), and searched a lot of information Still unresolved, after days of trying I finally figured out that the real problem was with the iostream.

Finally, if you are a student who wants to use codeblocks to upload large assignments like me, I recommend that you quote stdio.h and give up iostream, which can save a lot of trouble in configuration.

If it is changed to stdio.h and the error 0xc000007b still occurs, then go to see if the dll of the third-party library has not been put in.
