Solution

The question is incomplete as it doesn\'t mention the declaration of individual functions func1, func2....func6.

The value of the variable a/b/c will depend on the return value of the respective functions.

If the parameter passed is a reference, the value might as well get changed. But if it is passed as value, any changes will not reflect in the calling function.

Ex : c = func3 (a) --> a is passed by value, so the value cannot be changed globally and is not reflected in the calling fucntion.

b = func6(&a) -->  a is passed as reference, so the value,if changed in the called function will reflect in the calling function.
