Answer:

Use of unassigned local variable `a'

Explanation:

Required

What is true about the code

After declaring variable a as integer, i.e.

int a

For the program, a has to be initialized with an integer value

e.g. a = 5;

Initializing a will prevent the use of unassigned local variable error.

Since a is not initialized in the program, the program will return the above error for variable a.
