Using same values for num1, what are the values of idiv12 and fdiv34[ to second decimal accuracy]? num2, num3, num4 idiv12 = (num1um2) idiv34 = (num3um4); fdiv12 (float) num1um2; fdiv34 = (float) num3um4 ajidiv12- fdiv34 (b) Which is more accurate value idiv12 or fdiv34? Why? Which is more faster computation? (b) Which is more accurate why. Which is more faster--- Why-- Are the following statements valid? If not what is missing? Assume variables are already defined. c) scanf ("%d%d", num1, num2) If invalid, what is correct form c) Valid or invalid .d) if (x 10) product-x'x d) valid or invalid if inval lid, what is correct form
