88. try...catch

The code will output:

a1
b1
c1

Explanation:

• In the first try-catch block, because the catch block doesn't have an argument specified, the catch block will catch the error but not assign it to anything, so the global variable a will be assigned the value 'a1'.
• In the second try-catch block, the catch block has an argument specified as b, so the catch block will catch the error and assign it to a local variable b, which will shadow the global variable b. Then the local variable b will be assigned the value 'b1'.
• In the third try-catch block, the catch block has an argument specified as error, so the catch block will catch the error and assign it to a local variable error, which will not affect the global variable c. Then the global variable c will be assigned the value 'c1'.
