Question

do..the question number c......its

Answer 1

1. Operators are :
   (a) Prefix increment/decrement(++ --)
   (b) Unary plus/minus(+,-)

2. Because pointer store address which is of type int. the size of int is 2 bytes.  So the pointer will allocate 2 bytes of memory.

3.  = is called assignment operator. It is used to assign the value of right-hand side value/variable/expression to the left hand side variable.

Ex: int a = 2

== is called relational operator.It is used to check the value of left-hand variable/expression with the right-hand variable/expression.

Ex : if(a == 2). It returns either true or false.

4. Implicit type conversion is done automatically.    Conversion of smaller number to larger number is implicit.

Ex : float a=0;     
      int b=10;     
       a=b; 


Explicit Conversion is done programmatically. Conversion of the larger number to smaller number is explicit conversion.

Ex :  float b=123.456     
          int a= (int) b  


Hope this helps!
