Whats the reason behind this output?

Question

My sister was typing this and found this output, then she called me , and asked "What is this in the output?"
Actually she missed out the quotes while declaring the character. But even though the output should not be this.

Answer 1

This is a random garbage value that has been assigned to a and b. Without the quotes, a gets a's value, which was not assigned yet. and results in a garbage value. Thus you get the weird output. Similar things happen with b, but since b is a char, it gets restrained to an ASCII value...

Answer 2

Before initializing i.e. allocating a value to a variable it has its own value which is called as garbage value which is happing with int a. And as I think b is pointing to null. So to get proper output replace
int a = with any number
char b = 'any character'

Answer 3

I'm not sure that b is having garbage value as it displays nothing . So , either it's value is null or it's pointing nowhere that means no value is there .
