El_Farouq:
if i upload the code to the arduino will it cause a problem for me.
Not based on the warnings you posted. I can't say whether there was more output you didn't bother to post.
"deprecated conversion from string constant to 'char*'" means this was something that used to be supported and still is but they're planning to stop supporting it in some future compiler version and so they're warning people that it might be a good idea to fix the code now while it still works rather than waiting for the new compiler version to break it. Arduino is very conservative about updating to new compiler versions so it will be a long time if ever before that code is broken and even then you would have the option to revert to an older version that was still compatible with your code.
At this stage in your journey I'd advise you to just ignore it and move forward instead of letting this warning halt your progress.
