What is the different return type of a function?
The result of a function is called its return value and the data type of the return value is called the return type. If a function declaration does not specify a return type, the compiler assumes an implicit return type of int . The user-defined type may also be defined within the function declaration.
Can we overload functions using different return types?
No, you cannot overload a method based on different return type but same argument type and number in java. same name. different parameters (different type or, different number or both).
Can we have different return type in method overloading in Java?
In java, method overloading is not possible by changing the return type of the method only because of ambiguity.
Can we overload method with different return type C++?
No, you can’t overload by return type; only by parameter types, and const/volatile qualifiers. One alternative would be to “return” using a reference argument: void get(int, int&); void get(int, char&); although I would probably either use a template, or differently-named functions like your second example.
Which function has no return type?
Void functions
Void functions are created and used just like value-returning functions except they do not return a value after the function executes. In lieu of a data type, void functions use the keyword “void.” A void function performs a task, and then control returns back to the caller–but, it does not return a value.
What is no return value?
Function with no argument and no return value : When a function has no arguments, it does not receive any data from the calling function. Similarly when it does not return a value, the calling function does not receive any data from the called function.
Can a function be able to return different types?
You can use templates, if you know what type to return before you call the function. But you can’t have a function, which internally decide to return some type. What you can do is to create a class which will be a container for returned data, fill object of this class with desired data and then return this object.
Can a method have the same parameters and a different return type?
You can not have a Method of the same name with the same parameters and a different return type, the caller would not know which Method to call (will not be able to resolve the location in Memory of the Method to call, why the Compiler would not allow it).
Can You overload two functions with the same return type?
You cannot overload two functions with the only difference being a return type. C# uses the parameter list as the context. You could have the function return an object and typecast it in the call. You could include a dummy variable in the header to differentiate the method context.
How to call same function parameters with different return type in C + +?
It would be: AnotherFunction (RetrieveValue (dataString1)); // param of type int AnotherFunction (RetrieveValue (dataString2)); // param of type double But that doesn’t work in C++ (obviously). Right now, we’re having it set up so that they call:
