Detailed Description

This is a driver program to test the functions defined in numConv.h and implemented in numConv.c. The program takes up to three command line parameters and calls one of the methods, then prints the results. To see how to use the program, execute ./testConv in a terminal window. This will print a usage statement defining how to run the program. The 1st parameter of the program is always a key defining which function to run. The options are:

• i2c convert a number to a character digit (tests int2char())
• c2i convert a character digit to its integer value (tests char2int())
• dnr test the divRem() function
• a2i convert a string of characters to a number (tests ascii2int())
• i2a print the digit(s) of a number specified by a string (tests int2ascii())
• f2d convert a string representing a fraction into a double (tests frac2double())

The 2nd parameter is always the radix you work in (2..36). The 3rd parameter depends on the function.

A sample execution might be: testConv c2i 16 A

All numbers are unsigned.

Entry point of the program

Parameters

argc	count of arguments, will always be at least 1
argv	array of parameters to program argv[0] is the name of the program, so additional parameters will begin at index 1.

Returns

0 the Linux convention for success.
