How can I return multiple values from a function in C++?
While C++ does not have an official way to return multiple values from a function, one can make use of the std::pair , std::tuple , or a local struct to return multiple values.
How many values can a function return using a C++ return statement?
A C++ function can return only one value.
Can return return multiple values?
JavaScript functions can return a single value. To return multiple values from a function, you can pack the return values as elements of an array or as properties of an object.
How can I return 2 values in return?
Returning Multiple values in Java
- If all returned elements are of same type.
- If returned elements are of different types.
- Using Pair (If there are only two returned values) We can use Pair in Java to return two values.
- If there are more than two returned values.
- Returning list of Object Class.
How can I return multiple values from a time in C++?
For returning two values I use a std::pair (usually typedef’d). You should look at boost::tuple (in C++11 and newer, there’s std::tuple ) for more than two return results. With introduction of structured binding in C++ 17, returning std::tuple should probably become accepted standard. +1 for tuple.
Can you have two return statements in a function C++?
You can have multiple return statements and it should not matter, if you are returning the same variable. However if you have multiple variables in your function and you return then differently depending on the code flow the compiler cannot perform such optimisation.
How many maximum values can a function return using return statement?
one value
Even though a function can return only one value but that value can be of pointer type.
Can a function return more than one value C++?
A C++ function can return only one value. However, you can return multiple values by wrapping them in a class or struct. Or you could use std::tuple , if that is available with your compiler.
Which data structure allows return multiple values from a function?
You can return multiple values from a function using either a dictionary, a tuple, or a list. These data types all let you store multiple values.
How many values can a function return at a time?

Is it bad to have multiple return statements?
Multiple return statements in a method will cause your code not to be purely object-oriented. Here you’ll find an example where you can use a clean OOP approach instead of using multiple returns. All arguments in favor of multiple return statements go against the very idea of object-oriented programming.
How do I return multiple values from a function?
Passing arguments By Reference is probably the most common way to return multiple values from a function. It uses the ByRef keyword to tell the compiler that the variable passed to the function is only a pointer to a memory location where the actual value of the variable is stored.
Can We return multiple values from a function?
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. So we have to pass the address of the data. In this example we will see how to define a function that can return quotient and remainder after dividing two numbers from one single function. Call By Address Example
What does return value mean?
The “return value” is the value you’re expecting to be returned. In this case the return value is the person’s name of the object you pass to the function.
