Can you have multiple returns in a function?

Even though a function can return only one value but that value can be of pointer type. If we want the function to return multiple values of same data types, we could return the pointer to array of that data types.

How many return statements are allowed?

Answer: If the given value is Zero, a ‘0’ is returned. So, only one return statement is executed at run time even though the function contains multiple return statements. Any number of ‘return’ statements are allowed in a function definition but only one of them is executed at run time.

In which case finally block will not be executed?

A finally block will not execute due to other conditions like when JVM runs out of memory when our java process is killed forcefully from task manager or console when our machine shuts down due to power failure and deadlock condition in our try block.

How many functions can a return statement?

Python functions are not restricted to having a single return statement. If a given function has more than one return statement, then the first one encountered will determine the end of the function’s execution and also its return value.

Does a function need a return statement?

NO, a function does not always have to have an explicit return statement. If the function doesn’t need to provide any results to the calling point, then the return is not needed.

Can a method have no return statements?

Any method declared void doesn’t return a value. It does not need to contain a return statement, but it may do so. The data type of the return value must match the method’s declared return type; you can’t return an integer value from a method declared to return a boolean.

What is it called when a function calls itself?

A function is called a recursive function if it calls itself again and again . Recursion can be direct as well as indirect. Direct recursion is when a function calls itself. Whereas indirect recursion is when a function calls another function and the called function in turn calls the calling function.

What is the default return type?

The default return value from a function is int. Unless explicitly specified the default return value by compiler would be integer value from function.

Can we have multiple return statements in C?

In C or C++, we cannot return multiple values from a function directly. We can return more than one values from a function by using the method called “call by address”, or “call by reference”. In the invoker function, we will use two variables to store the results, and the function will take pointer type data.

What will happen when catch and finally block both return value?

When catch and finally block both return value, method will ultimately return value returned by finally block irrespective of value returned by catch block. In above program, try block will “try”, but ultimately control will enter finally block to return “finally”.

What is difference between final finally and finalize?

Final class can’t be inherited, final method can’t be overridden and final variable value can’t be changed. Finally is used to place important code, it will be executed whether exception is handled or not. Finalize is used to perform clean up processing just before object is garbage collected. Final is a keyword.
