Question
what is syntax error, logical error & data error in c language, if there is any other in thi language please tell me .

Answer
Every language has got set of rules.
If you make a mistake while using the language, then it is called syntax error.

You are writing program to solve a problem.
So, there is a set of input and you expect some output.
If there is difference between the expected o/p and actual o/p, then your program logic is wrong. This is called Logical Error.

I haven't heard about "Data Error"! Is it that, the input data itself is wrong!?
If so, then it is not related to C programming....it is the problem with the person inputting the data!
