For Loop Statement Pattern to use in Parser

[gamer1127]

Hello, I'm creating a program that parses a for loop statement, i can do all other things that were need for a parser, now my problem is the pattern to check if the for loop statement that the user entered is correct.

Here is the pattern:

public static string forLoopPattern =
          @"([for])" +
          @"([(])" +
          @"([int]\ \\)" +
          @"([a-z])" +
          @"([=])" +
          @"([0-9])" +
          @"([;])" +
          @"([a-z])" +
          @"([>,<,=,<=,>=,=<,=>])" +
          @"([0-9])" +
          @"([;])" +
          @"([a-z])" +
          @"([++,--])" +
          @"([)])";

Is the pattern correct? If not what should i change in the pattern and how will i be able to check it if that pattern is working or correct?
