Write four functions. The first two functions will translate the parameter passe

Question

Write four functions.

The first two functions will translate the parameter passed
to it into integers in the range 0-9.
- The first function will translate the letters 'A'-'J'
to the range 0-9.
- The second will translate the integer values 1-10 into
the range 0-9.

The third and fourth functions will be boolean functions
that test to see if the values passed into them are in a
specific range.
- The third function will be passed a character and will
produce true if it is in the range 'A'-'J'.
- The fourth function will be passed an integer and will
produce true if it is in the range 1-10.

Have your program read in a character and an integer.
Then print the translated results in the range of 0-9 or
print a message indicating that they are not in their
expected ranges.

Ex 1:
----

Enter a char: B
Enter an int: 12

'B' translates to 1.
12 is out of input range.

Ex 2:
----

Enter a char: Z
Enter an int: 5

'Z' is out of input range.
5 translates to 4.

Explanation / Answer

A function is similar to a subroutine (Gosub) except that it can accept parameters (inputs) from its caller. In addition, a function may optionally return a value to its caller. Consider the following simple function that accepts two numbers and returns their sum: Add(x, y) { return x + y ; "Return" expects an expression. } The nextfile statement presented in section The nextfile Statement, is a gawk-specific extension. It is not available in other implementations of awk. This section shows two versions of a nextfile function that you can use to simulate gawk's nextfile statement if you cannot use gawk. Here is a first attempt at writing a nextfile function. # nextfile -- skip remaining records in current file # this should be read in before the "main" awk program function nextfile() { _abandon_ = FILENAME; next } _abandon_ == FILENAME { next } This file should be included before the main program, because it supplies a rule that must be executed first. This rule compares the current data file's name (which is always in the FILENAME variable) to a private variable named _abandon_. If the file name matches, then the action part of the rule executes a next statement, to go on to the next record. (The use of `_' in the variable name is a convention. It is discussed more fully in section
