Answer:
Declare variable b in both lines
i.e. int b
Explanation:
In the given code, the parameters of both functions were not properly declared.
When listing the parameters, the data type must be clearly stated for all parameters (individually)
In the declaration of both functions, only variable a is declared as integer while b is undeclared.
So, the correction is to declare b as integer
