It is known that 1 cm is equal to 0.3937 inch and 1 inch is equal to 2.54 cm. Write a program to convert 0, 0.5, 1, 1.5, ..., 8, 8.5, 9, 9.5, and 10 from cm to inch and from inch to cm.

Click! --------------------------------------------------------------- ! This program "contains" two REAL functions: ! (1) Cm_to_Inch() takes a real inch unit and converts ! it to cm unit, and ! (2) Inch_to_cm() takes a real cm unit and converts it ! to inch unit. !

- Function
**Cm_to_Inch()**converts its formal argument**cm**to inch, which is returned as the function value. Please note that the constant 0.3937 is defined as a**PARAMETER**. - Function
**Inch_to_Cm()**converts its formal argument**inch**to cm, which is returned as the function value. Please note that the constant 2.54 is defined as a**PARAMETER**. - The main program uses
**DO-EXIT-END DO**to generate 0, 0.5, 1, 1.5, ..., 8, 8.5, 9, 9.5 and 10. For each value,**Cm_to_Inch()**and**Inch_to_Cm()**are called to perform the desired conversion.
