Function with Default Parameters

Learn about the default parameters of functions.


Write a program that defines a function that receives 5 arguments of types char, int, long, float, and double in that order. If we call this function in three different ways (once, with values for all five arguments, then with values for only the first four arguments, finally with values for only the first three arguments) the program compiles and runs fine. If the last argument is omitted, it should take on the value 6.28 by default. If the last two arguments are omitted, the fourth argument should be taken as 3.14 and the fifth argument as 6.28 by default.

Sample run

Here’s what you should see when you run the program.

1. First call with all 5 arguments:

A 12 123 0.5 -1.5

2. Second call with first 4 arguments:

B 1234 12345 4.5 6.28

3. Third call with only first 3 arguments:

C 987 9876 3.14 6.28
