ConvertDec_to_Hex-Oct-Bin.c

ConvertDec_to_Hex-Oct-Bin.c is a simple conversion program that prompts the user for their name and the current date, followed by a prompt for an integer from 1 to 1,000,000. The integer entered will be displayed in hexadecimal, octal, and binary representation. Conversions must be computed algorithmically (i.e. NOT accomplished via format specifiers ). The user is then asked if the output should be saved to a text file. If user replies in the affirmative, a name for the text file is requested. The newly created text file will contain the users name, current date, and output results (see example below).

User defined functions:

As a minimum, include the following 2 user-defined functions: (prototypes may vary as long as the function works properly)

char *getDateAndTime();

Returns a character string with the current date and time

int getInteger()

Read user input into a character string.

x returns -1 to exit program.

Otherwise, convert the string into an integer (which will be returned to main()) using

int atoi(const char *str);

or

int sscanf(const char *s, const char *format, ...);
