What is an example of a logical procedure?

Answer 1

A logical procedure is any procedure that identifies the unknown from the known.

For example, a procedure that returns the maximum of any two given values has two known variables (the given values) and one unknown variable (the result). By logically examining the known, the unknown can be determined.

Given the values x and y, the logical process can be reduced to the following pseudocode:

If x is greater than y then return x otherwise return y.

In C++, we'd encode this logical procedure as follows:

template

T& Max( T &x, T &y ) { return( x>y?x:y ); }
