weight 2. vs weight 2
Answer=A. 2
This is because the input informat is improperly used to read the data. Since there is no period right after 2, the input statement starts reading weight at COLUMN 2. Thus, it reads “2” and then a space, so 2 is input as the value for weight. The correct statement to read the data properly would be:
input @1 height 2. @4 weight 2.;
