I'm taking my first steps in learning to code in C (using the books 'C programming Absolute Beginner's Guide (Perry + Miller)', and 'Programming in C (Kochan)') . I'm about 2/3 + 1/3 of the way through the books. Last week, using X-code 7.3's IDE, I was able to build and run the programmes I typed in, and the answers came out correct. Then on Saturday, I created a programme that built and ran but gave the result 0.0000. So I tried using the break arrows, but didn’t understand the explanations about threads. So I searched for a button that would allow me to step through the programme one instruction at a time whilst I observed the changing values of the variables and the inputs to them. I pressed a lot of buttons, but could find it.
Since then I’ve been unable to run any programme. (Did I unwittingly give a stop instruction to the IDE ?)
The build is successful, and then a pop-up appears saying - Developer Tools Access needs to take control off another process for debugging to continue. Type the name and password of a user in the “Developer Tools” group to allow this, (followed by an input box for Username and Password). I’ve tried putting in my Apple ID, Developer Forum username etc. … all to no effect.
So could someone please advise me on - What steps must I take in order to obtain a Username and Password that’s valid for the “Developer Tools” group?
Many thanks in advance for any advice offered.
