Dear Miguel. Thank you for replying to my query on the forum.
I realise your role is to help with more complex problems, but I seek to offer a report.
I have written thousands of lines of source code in Basic, and in Z80 and 6809 Assemly language, but this foray into C++ with Codeblocks has got me baffled.
I have studied the information that you kindly made available.
The only response in the lower box is "checking the existence of............".
When I can get the Command line to appear, It will not accept any input.
It is regrettable that this simplest source code program does not work on Codeblocks (It works perfectly on an Online C++ Compiler). I am assuming that "build and run" means "compile and execute"
If I cannot get a simplest routine to work on Codeblocks, then I am lost.
Today`s beginner can be tomorrow`s dedicated user, but it is not working at the simplest level.
David.
