Consider the following declarations.

 

int    sum1, sum2;

float  number;

double total;

          Initially the values of the variables are as follows:

sum1   = 10          number = 2.5f

sum2   = 20          total  = 10.25d

 

consider only the effect of each statement on the initial values specified above. By state which is invalid and not valid?

  1. a) number = sum1; ............
  2. b) sum2 = (int) total;         ............
  3. c) number = sum1 / sum2; ............
  4. d) sum1 = number * 4;          ............
  5. e) total = number;              ............
  6. f) number = sum2 % 2; ............
  7. g) sum1 = (int) (sum2 / 3.0f); ............
  8. h) number = (float) sum1 + 2.0; ............
