Consider the following code: static void Main(string[] args) { int a; Sample1(ref a); Console. WriteLine(a); Sample2(out int b); Console. WriteLine(b); } static void Sample1(ref int value) { value = 2; } static void Sample2(out int value) { value = 4; }

Which of the following is true regarding the given code?

a. The error "Use of unassigned local variable a" will appear during compilation.
b. Line 4 will print the value of variable a as 2.
c. Line 6 will print the value of variable b as 2.
d. The error "Multiple declaration of the value variable" will occur during compilation.

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.

there is no universally accepted definition of art. although commonly used to describe something of beauty, or a skill which produces an aesthetic result, there is no clear line in principle between (say) a unique piece of handmade sculpture, and a mass-produced but visually attractive item. we might say that art requires thought - some kind of creative impulse - but this raises more questions: for example, how much thought is required? if someone flings paint at a canvas, hoping by this action to create a work of art, does the result automatically constitute art?
