Write a program that reads a C++ source-code file and reports the occurrence of each keyword in the file. Here is a sample run:

``` Enter a C++ source file name: Welcome.cpp int occurs 3 times void occurs 1 time ... static occurs 1 time ``` Suppose a set of keywords is already given as follows: ``` set s; s.insert("asm"); s.insert("auto"); s.insert("bool"); ... s.insert("while"); ``` So you don’t need to populate the set in the program.
