A
Can you give some explanation?
Weight is assigned value of 2, instead of using a 2. informat. try it.
above explaination is worng…its is not assigning value 2…but it is selecting column 2 value from raw file which is 2…try with the different numbers….
james is correct
@3, I think your explanation is wrong, weight 2 means column input, so input value of 2, you can try weight 1, then you will find the value of weight is 7.
D is the correct answer try it
wrong explanation James, the 2 is read from the second column of the raw data file. Please check.
