getint

free-format input conversion to one integer per call. Section 5.2 of The C Programming Language.

About the project:

• getint performs free-format input conversion by breaking a stream of characters into integer values, one integer per call.
• Returns the value it found and also signal end of file when there is no more input.
• These values have to be passed back by separate paths, for no matter what value is used for EOF, that could also be the value of an input integer.
• In this example, getint return the end of file status as its function value, while using a pointer argument to store the converted integer back in the calling function.

getint results:

• getint can be run with the following ways to enter inputs:

  • Sequentially:
    
  • OR one a time:
    

• Last thing the function prints is the array of size SIZE (SIZE = 10 in this example)

What did I learn from this:

• Input streams in C.
• Arrays, pointers and indexing.
