IPhone 5c screen is black

My iPhone 5c died a couple days ago so I plugged it in and realized it wasn't charging. I've left it on the charger for a sol day and still nothing it would just vibrate every 10 seconds. I also tried restarting it by hold the sleep and home button for 10 seconds but still nothing. Any ideas what happened? Also if I get this checked out by apple how much will it possibly cost to fix?

My cellular data isn't working?

I have an iPhone 6 and recently my data hasn't been working. Say I want to use Spotify without Wi-Fi, so I go into the data settings and turn on Spotify. Then I open the app and it says offline. I go back to settings and it's turned off so I tried turning it back on again then switching back to Spotify and it's turned off again! This happens with all my apps but Snapchat. I have no idea how to fix this so if someone knows please let me know it's super annoying!

Source of good tutorials on iphone apps?

Basically i'm just looking for easy to understand tutorials, i'm getting old lol, i'm using a windows based machine and to make it more complex i'm a C++ coder, (and yes i use the ultra complex notepad. ) with a command line linker and compiler of course lol. The tutorial must include socket programming - thats the bit i can't find.

The app for anyone interested is dead simple, my girlfriend takes a pic on her iphone and it saves it on her home NAS.

Added (1). Please don't provide code, i really want to understand how it works then ill be able to code a more robust program, i see too many people ask for code, and thats not the way to learn coding, whilst my skills date way back, they are still relevant. Just these days things change so fast i kind of got left in the past a bit, and would appreciate a bit of a helping hand to guide me to a tutorial.

My IPhone 5c is frozen on the lock screen, what do I do?

I haven't dropped it at all, and I've restarted it (held down the home and sleep/wake buttons) twice, but it still won't unfreeze. I've also tried charging it but that didn't work. What should I do? (I can't take it to an Apple store as they don't have one where I live)
