Menu Driven Code Compiler Errors

jaysparks (1)
New C++ student seeking assistance with reviewing the compiler errors in my code. Have done some research online and have had little success with a remedy for my errors. Currently using Dev C++ as a required compiler. Thank you in advance for any guidance provided.

line 77 : add ';' a the end

line 119: opt[ i ] <- What is it? you forgot to declare this array ..

line 9: you declare 'LoadExam()' but you have not defined this function
