Write a program ： To count the number of following data:

1. word, consist of letter, a~z, and A~Z

2. number, consist of 0~9 and “.”, “%”, meanwhile, judge the type of it:

a) int

b) float

3. Special character, such as “@, ^,! ,? , /, &, *, (,)” etc.

A paragraph of a text, that is to be tested and analyzed, is entered from the keyboard. The text file is created by the program first. Please use struct and pointer to record statistically and, after tidy them up, please display the number of each type and the classified data.
