This problem happened after a while of using Codeblocks , and I'm not able To find an answer on Google , I write whatever on the IDE and I get Always the Same message : hello World and this is the log message and you can see it at the picture , Yes you can say use Visual Studio Code , but I'm studying on Codeblocks because of the school teacher is using it .
I tried to clean install codeblocks , and I even removed Visual Studio Code , and I removed Dotnet after I got that crazy problem .
thankfully the problem was just me creating a header instead of a source C/C++ , just be careful what you are choosing in the first menu.enter image description here
