Hi,
This is a simple question with if elseif....however I am having trouble
constructing the solution for some reason.
Suppose I have a data set with 3 variables, a, b and c say. Let's say c
is the sum of a and b. So:
a b c
1 2 3
2 3 5
3 4 7
. . .
. . .
. . .
Suppose that I know there have been some data entry errors and I want to
check if ALL values in c is really the sum of a and b, and if not, print
out the whole line (i.e. all values of a, b and c in that row).
Any help on how I can write this if elseif block will be apprecaited!
