How do you return a statement in C++?

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.
Can you return multiple values from a function in C #? Provide some examples?
No, you can’t return multiple values from a function in C# (for versions lower than C# 7), at least not in the way you can do it in Python. However, there are a couple alternatives: You can return an array of type object with the multiple values you want in it. You can use out parameters.
Can function return multiple values?
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.
Can a function have multiple return statements?
A function can have more than one return statement, but only ever run one based on a condition.
How do you return a variable from a function?

How can I return two variables in C#?
We can return multiple values from a function using the following 3 approaches: Reference parameters….You can call the function using the following code:
- int a=10, b=20;
- MinMax results = MultipleReturns(a,b);
- Console. WriteLine(“Minimum Value: ” + results. min);
- Console. WriteLine(“Maximum Value: ” + results. max);
How many ways a function can return values?
A return value can be any one of the four variable types: handle, integer, object, or string. The type of value your function returns depends largely on the task it performs.
How many return statements can be included in a function C++?

How many values can a function return in C++?

How does return work in C++?
How to return multiple values in C?
You can’t return multiple values in C. Your options are to return a struct, or to pass in references to the variables you want to modify: struct studio_stuff { int studio; int one; int two; }; struct studio_stuff foo () { struct studio_stuff ret; ret.studio = 0; ret.one = 1; ret.two = 2; return ret; }
Is it possible to return two variables from a function?
Technically, no you are not able to return two variables in the way you would normally return a variable. You can, however, use references. That way, you can pass multiple variables to a function, and the function will assign them, rather than returning anything: Show activity on this post.

How to return multiple values from a variable in Python?
Returning multiple values using Class and Object : The idea is similar to structures. We create a class with two integer variables and store the greater and smaller values into those variable, then use the values of that structure. Returning multiple values using STL tuple : The idea is similar to structures.
