'}' - semicolon expected

I was practicing to make a simple E.A.but the following errors occurs .

"        '}' - semicolon expected                             "

"        'else' - illegal 'else' without matching 'if'       " 

Can anyone please point out my mistake in the following program  and make the correction.
