Description
The Greatest Common Divisor program (gcd.c) calculates and prints the largest
integer which divides two other integers.
Input Format
Two integer arguments are given when the command is invoked.
Both must be greater than zero. For example, type
% gcd 3 21
Output Format
Output is a single sentence printed on the screen such as
The gcd of 3 and 21 is 7.
Operational Considerations
There are no special operational conditions. However, errors should be
reported for numbers that do not satisfy the above constraint and for
specifying too few arguments.
Executable
Windows executable: gcd_exe.
Rename this to "gcd.exe" after downloading.
