New problem. I dont understand how to convert a char/int to string

Lines 171 -176 are giving me problems. I dont know if im going about it all wrong. I read my book and it said to use the conversion functions that i tried using. They are not working as i intended and im sure it is because i have them being used wrong. Wondering if i could get some help on these issues?
