Main Function:
- Declares two integer variables,
aandb. - Asks the user to input values for
aandb. - Calls the
cvinterchangefunction withaandbfor Call By Value interchange. - Prints a newline for separation.
- Calls the
crinterchangefunction with the addresses ofaandbfor Call By Reference interchange.
cvinterchange Function (Call By Value):
- Displays a message indicating it's using Call By Value.
- Prints the values of
aandbbefore the interchange. - Swaps the values of
aandbusing a temporary variablec. - Prints the values of
aandbafter the interchange.
crinterchange Function (Call By Reference):
- Displays a message indicating it's using Call By Reference.
- Prints the values pointed to by
aandbbefore the interchange. - Swaps the values pointed to by
aandbusing a temporary variablec. - Prints the values pointed to by
aandbafter the interchange.
In this code, the main function is the entry point, and it calls two separate functions, cvinterchange and crinterchange, to demonstrate the difference between Call By Value and Call By Reference. The values of a and b are interchanged within these functions using different methods, and the results are printed to the console to illustrate the differences in how the two methods handle variable values.
